BN Series Control Devices from Pizzato, Capable, Versatile & Easy to Install

Pizzato Elettrica is one of the world’s leading manufacturers and suppliers of position switches, microswitches, foot switches, safety devices and control devices. Their comprehensive industrial automation solution portfolio contains the versatile range of BN series control devices, capable modular products that are the perfect control solution for many industrial process control applications. Kempston Controls has access to the entire Pizzato product range, so whatever you need we can get it for you at the best possible price.

BN Series – Simple to Install

The primary feature of the BN series control device range is their easy installation, the in-line holes make it simple to fit and wire and being plug-and-play, all you have to do is plug the connector in. In case the unit develops a fault or is damaged they can be replaced immediately thanks to their monolithic design, without the need for rewiring helping the user avoid any possible errors.

BN Series Control Devices

Versatile, the BN Series control device units are designed with rotatable modules that provide various installation options when mounting on the machine. After loosening the fixing screws, the upper and lower modules can be turned 90 degrees to the desired configuration. Another advantage is that the fixing modules cannot be detached from the device body.

Ingress Resistant

Disassembly of the individual parts is not necessary and there is no risk of losing parts or reassembling them incorrectly. The fixing screws are protected by push-in caps, which not only prevent dirt from accumulating, but they also block access to the screws and make it less likely someone will tamper with them.

BN Series Control Devices

The BN series control device unit is available in various configurations, designed to cater for a wide variety of installation applications: for standard applications, configurations with 3 or 4 devices are ideal, while configurations with 6, 7 or 8 devices are available for more complex applications, providing the user with more control and signalling devices in the same location.

Protected against accidental damage

Featuring recessed control devices in the outer housing means they’re protected from accidental knocks and damage leading to a longer operational life. They only protrude a little from the front face, so the BN series remains within a maximum width of just 40 mm.

BN Series Control Devices

In all of the BN series device configurations, a variety of control devices can be installed and also illuminated by integrated LEDs. The buttons feature lenses that can be laser marked for a resistant, indelible engraving, allowing the user to customise the lenses with a wide range of text and symbols

The Pizzato Elettrica BN series of modular control device units have the same shape and dimensions as the RFID safety switches with lock belonging to the Pizzato NS series, giving machine manufacturers who already use the NS series the chance to create a uniform installation that is aesthetically pleasing.

Safety Switches with RFID and Electromagnetic Security from SICK

What are Safety Switches?

Safety switches are indispensable in many industrial processing applications where safety is essential for the protection of both personnel and machinery. They are ideal for protecting and monitoring the movable physical guards, doors and access panels found on machines and production lines.

Why use Magnetic Safety Switches?

Magnetic safety switches are one solution to monitoring safety guards, with low-wear and low-maintenance. With extended service lives magnetic safety switches are also resistant to shock and vibrations and offer a high level of protection against manipulation.

Dependable, magnetic safety locking switches provide very high reliability for door monitoring and use a strong electromagnet to ensure that the safety guard is closed and the production process runs smoothly.

Industrial installation that requires protection

With the incorporation of RFID transponder technology, different coding levels can be achieved – with universal coding all actuators are accepted; with unique and permanent coding only the previously taught-in actuator is accepted.

SICK is one of the world’s leading manufacturers of sensors and sensor solutions for industrial automation applications. Here we take a quick look at their MLP1 Magnetic Locking Safety Switches, their advantages and applications.

SICK MLP1 Safety Switches with RFID and Electromagnetic Security

The SICK MLP1 safety switches main feature is  magnetic locking, specifically designed for industrial applications that require process protection and a safety function. These safety switches also feature an RFID transponder that acknowledges and monitors the semiconductor outputs, providing maximum safety for door and guard monitoring. The electromagnet ensures that the safety door stays closed and the production process is not interrupted.

The combination of these two low-wear technologies provides high door offset tolerance, increased safety and increased machine availability. The innovative mounting concept and flat actuators of the MLP1 facilitates easy integration into your installation.

MLP1 Safety Switch Features

  • Actuators with low or high coding level
  • High level of manipulation protection through the use of RFID technology
  • Discreet integration into the machine design
  • Magnetic locking force: 500 N, retaining force: 25 N
  • PL e, category 4 (EN ISO 13849), SIL 3 (EN 61508) for door monitoring
  • Increased availability thanks to the high door offset tolerance
  • Offset tolerance: ± 5 mm
  • Standardised or integrated mounting
  • Variants with two M12 plug connectors for simple cascading
  • Simple and safe series connection reduces wiring work.
  • Mount the MLP1 directly on the door frame or inside the machine
  • Save time and money with simple connections and low wear & tear
  • Enclosure rating: IP67

Safety Switches from SICKin Series

Optimal Process Protection

The MLP1’s strong electromagnet prevents interference in running processes, ensuring that the safety gate remains closed and the production process can function as planned. Further benefits come with the high level of manipulation protection provided by the RFID transponder safety switch, variants with unique coding only accept the previously taught-in actuator.

The high locking force of the electromagnet ensures that the protective door cannot be opened accidently. These safety switches have an offset tolerance of ± 5 mm and, thanks to the transponder technology and electromagnet, provide a reliable door locking function even if the door is not closed correctly.

Safety Switches from SICK

Flexible Mounting, Easy Integration

It’s simple to integrate the MLP1 into your installation, being easily and quickly mounted and barely visible. Thanks to its rugged metal housing and IP67 enclosure these safety switches can withstand harsh ambient conditions providing a long service life. They also feature various connection options and performance level (PL) e.

Safety Switch Applications

WRAS Approved Valves for the Water Industry from Burkert

What does WRAS approval mean?

In the busy water industry, WRAS approval is the simplest and most recognised way to comply with Water Supply Regulations. Approval is granted by the Water Regulations Advisory Scheme (WRAS), which aims to prevent the contamination of public water supplies and encourage the efficient use of water. This approval demonstrates UK regulations compliance of water fittings that transfer water to and from the public mains supply.

It is a legal requirement in the UK that a water fitting should not cause waste, misuse, undue consumption or contamination of the public water supply. Water fittings must also be of an appropriate quality standard. The requirements are part of the Water Supply (Water Fittings) Regulations or Scottish Byelaws and all water fittings that carry or receive water from the public mains supply must comply.

Why is WRAS approval required?

This type of approval demonstrates that the non-metallic materials or components used in the construction of a fitting, such as rubber sheet material, doesn’t itself contaminate the water.

What is WRAS material approval?

Manufacturers declaring equipment for WRAS approval must use WRAS approved fittings or WRAS approved materials and components. WRAS approval uses BS6920 material testing which verifies that the materials or components, such as a seal, does not cause water contamination.

Burkert Fluid Control System Valves with WRAS Approved Materials

Burkert, one of the leading manufacturers of fluid control systems, has designed and manufactured an exciting range of WRAS approved seals.
