ST-G RFID Sensors with Multi-tag Ability for Industrial Process Control and Safety Applications

RFID or Radio Frequency Identification uses a digitally encoded tag with information that can be read and captured by a reader using radio waves. A basic RFID system consists of the tag, and an RFID reader. Typically, an RFID tag transmits digital information to an RFID reader within close proximity, which then converts that information into usable data for interpretation and a system response from another piece of equipment. RFID has found multiple uses within industry, including process control and the increasing the safety of machine guarding.

Pizzato are a well-known manufacturer of process control equipment including a broad range of machine access and safety control devices including Safety Hinges, Safety Modules and Limit Switches.

RFID Sensors – Positional Accuracy

The Pizzato’s ST-G RFID sensors extend all the technology used in their traditional ST-D series sensors, and do that in an even more compact housing.  The RFID technology within provides each actuator with different coding, making it impossible to tamper with a device by using another actuator of the same series. Ultimately, this means millions of different coding options are possible for the actuators, classifying them as high-level coded actuators according to EN ISO 14119.

Versatile, these RFID sensors are suitable for a host of process control applications and the clever housing design allows the same sensor to be used on both left and right-hand safety doors by simply rotating the sensor onto itself. The industry standard 22 mm fixing pattern and compact external dimensions means traditional magnetic sensors can be easily replaced with these more sophisticated RFID Sensors, providing maximum reliability and safety. The robust monolithic housing allows the ST-G RFID Sensors to be used in even the most aggressive industrial environments and the signalling LEDs providing immediate diagnostics of the input and output operating states.

ST-G RFID Sensors and Actuators

Within this range of industrial sensors is an extended temperature version that is certified by ECOLAB, this ensures that these sensors are ideal for machines used in the food and pharmaceutical industry. Constructed with redundant electronics means that the maximum PL e and SIL 3 safety levels can be obtained via the use of a single device on a guard, avoiding expensive wiring and speeding up installation.

ST-G RFID Sensors and Actuators

Multitag Programming

What sets the ST-G series of RFID sensors apart from the competition is an exceptional feature which Pizzato has called Multitag. Multitag is the ability of the sensor to recognise 2 or more actuators in a processing environment. The internal firmware can be factory programmed, memorising up to 16 actuators and associating a different device behaviour to each once the actuator has acknowledged the sensor. This ability allows the user to activate or deactivate the sensor outputs and send information regarding which actuator is in front of the sensor via an O3 signalling output. This signal can be sent to a PLC and processed.

ST-G RFID Sensors and Actuators

This Multitag function is ideal for machines and industrial processes with several workstations that require various operating modes based upon the recognition between different actuators and the sensor – such as during the change-over of machine parts, robot positioning during manufacturing, industrial process rotary tables control and so on.

For safety gate applications the combination of a sensor and 2 actuators can fully monitor safety guard opening and closing by acknowledging when the guard is fully open and again, fully closed, eliminating the uncertainties caused by incomplete guard positioning and ultimately increasing intrinsic safety.

Safety Door Switches with Highly Visible Indicators – The Panasonic SG-P Series

Over the years within your typical industrial production installation staff and processing machines have traditionally worked separately.  Today, with the growth of smart factories and people and machines working in unison the equipment’s ability to recognise interaction with their human counterparts becomes ever more apparent.


process line

Switches and actuators that can disable safety guards and doors are still being used at production facilities, which has proven to be one of the contributing factors in causing serious workplace accidents. However, there was another problem. Machines could not be operated immediately when using switches with small indicators because it took time to check the open/closed status of the doors of the entire production installation.

safety door switches

To try and solve this problem the engineers at Panasonic developed the SG-P Series Safety Door Switches. These durable safety switches enable operators and engineers to view the open/closed state of safety gates, guards of an entire production installation at-a-glance. These clever safety switches incorporate a switch unit and a paired actuator. During operating the switches only detect their matching actuator, this prevents the intentional disabling of the safety interlock and increases the safety of workers during operation and servicing. Other advantages include reducing machine downtime and improving productivity and through-put.

Prevention of the disabling of interlocks

During the maintenance of industrial production installations, intentionally disabling interlocks when opening equipment doors can be a major cause of accidents in the workplace, such as when another user operates the machine without noticing someone is still inside. The SG-P safety door switches prevent intentional disabling by utilising RFID that detects only the actuator that has been paired with the safety door switch.

safety door switches

Large and bright indicators show the open/closed state of the safety doors

These safety door switches are equipped with a bright and highly visible indicator, despite their small stature. Open safety doors and guards display a bright red light, other safety doors linked to the open doors are identified with green flashing lights to show that there is an unsafe status.

safety door switch, illuminated version



Traditional switches with a small indicator light are not easy to see when mounted on the inside of safety doors, making it hard for staff to identify which doors are open. Overcoming this problem, the Panasonic SG-P visible type features an actuator and switch that are both illuminated, while the switch body of the compact version illuminates on both sides, the actuator has no lighting. This highly visible status identification allows operators to ascertain the switch status and rapidly identify which doors are open, improving safety, reducing machine downtime and increasing through-put.

Short Circuits, Shocks and Overloads? Not a Problem with a CBR!

Dangerous short-circuits and overloads can occur at any time within an electrical system and for a variety of reasons. Therefore, it makes perfect sense that your installations are as safe as possible for everyone using them and for every device involved. Ensuring your electrical system and installations are kept as safe as possible from overloads and short circuits relies upon on a variety of devices including RCDs, MCCBs, Circuit Breakers and many others.

Space Saving Solution

To help you save valuable space and to protect your valuable installations and the people using them the busy team from Terasaki have created the TemBreak 2 CBR – Circuit Breaker with Integral Residual Current Protection range. This clever series of devices has been designed to provide protection against electric shock, overloads and short circuits giving the user three types of protection.

Circuit breakers with integral residual current protection (CBRs) are designed to protect against the hazards presented by earth leakage. Before the TemBreak 2 CBR was designed CBRs were only available as combined units, meaning that the circuit breaker was mechanically and electrically coupled to an earth leakage module.

Integral Earth Leakage

The Terasaki 2 CBR differs from this as the earth leakage function becomes an integrated feature of the device and is physically based on their popular TemBreak 2 MCCB range. The CBR is the first integral ELCB which complies with IEC 60947.2, Annex B, incorporating residual current protection. Switchboard manufacturers can use standard MCCB assemblies for dimensions and mounting, and no ampere de-rating is necessary. Reduced electrical and mechanical connection complexity ensures a higher reliability and lifespan, while the common dimensions of the unit means it is easy to replace the standard Terasaki range of MCCBs with the CBR units.

Short Circuits protection TemBreak 2 CBR

This capable CBR range features advantages such as adjustable residual current tripping thresholds, adjustable time delay, adjustable overload protection and a built in trip indicator and separate test button. Space saving, the TemBreak2 CBR has the same physical dimensions and mountings as the popular Tembreak 2 MCCB and eliminates the need for an external relay with current transformers and add-on block. Ideal for controlling overloads, short circuits and preventing shocks within numerous industries including the mining industry, temporary site supplies, heavy industry and commercial building use.

TemBreak 2 CBR Features and Specifications

• Number of poles 3 and 4 pole versions
• Nominal current ratings from 20 to 250A depending on the model
• Rated operational voltage 525V
• Voltage presence LED
• Trip Indicator – yellow button pops up to indicate tripping due to residual current
• Type A tripping is ensured for residual sinusoidal AC in the presence of residual pulsating DC
