RFID or Radio Frequency Identification, to use the full terminology, is a technology that uses a digitally encoded tag whose information can be read and captured by a reader using radio waves. A basic RFID system consists of the tag, a reader and an antenna.
Typically, an RFID tag contains a circuit and an antenna which transmit digital information to an RFID reader, which then converts that information into usable data for interpretation and possibly a system response from another piece of equipment (such as an alarm). Apart from the more obvious applications such as a security door pass card or a supermarket clothing tag, RFID has found multiple uses within industry, including the safety aspect of machine guarding.
Pizzato Elettrica are a global name in the realms of industrial process control and automation components including a broad range of machine access and safety control products such as Safety Hinges, Emergency Stop devices, Safety Modules and Limit Switches to name just a few.
Utilising their industrial knowhow and combining that with RFID technology the busy design engineers at Pizzato Elettrica have expanded the range of ST series RFID Safety Sensors with the extremely versatile and capable ST-H versions. The ST-H series Safety Sensors are equipped with all the advanced technical and operating features that you would find in the original Pizzato ST-G series, including:
- M12 plastic or stainless-steel connector
- Multicolour signalling LED, visible from both sides of the housing
- Multi-tag programming
- Versions for wide temperature ranges from -35°C to +85°C
The ST-H series Safety Sensors can be configured with a permanent magnet incorporated inside the housing which will generate a holding force between the sensor and actuator. Using this method, a safety guard can be kept closed even in the presence of vibrations such as those found after a recoil during the closing of a safety door, or in areas where air turbulence caused by fans, air lines or ventilation can open lighter safety guards.
The magnetic holding force of the ST-H range of RFID enabled safety sensors can be selected among three different levels to adapt to any safety gate and guarding application. Cleverly designed, the symmetrical housing with standard hole spacing allows the same safety sensor to be used on both the left and right-hand doors by simply rotating the sensor onto itself. The 78 mm mounting hole spacing facilitates the replacement of the traditional Pizzato SR-B magnetic sensors with an advanced ST-H RFID Safety Sensor.
RFID ST-H Series Features
- Uses existing technology from the ST-G Series Safety Sensors
- User configurable magnetic holding force of the actuator
- Easy to mount symmetrical housing
- Same mounting hole spacing (78 mm) as for SR-B series Magnetic Safety Sensors
- Compatible with all ST series actuators
- Protection ratings of IP67 and IP69K for use in the toughest conditions
