Optimise your safety system and establish exceptional security for your machine guard with the Sensaguard RFID rectangular non-contact safety switch by Allen Bradley Guardmaster.

The Sensaguard safety switches have advanced latest generation Radio Frequency Identification technology for coding and inductive technology for sensing, making them highly tamper resistant and dependable. They feature a wide sensing range and tolerance to door misalignment. Designed to be installed on machine guard doors, these non-contact switches offer a superior level of security and protection to reduce risk of injury, damage to equipment, and overall downtime. The Sensaguard range is perfectly suited to meet a wide range of industrial applications.

• Highly tamper-proof due to secure RFID sensing
• No dedicated controller is required
• Can be connected in series with other safety components (light curtain, E-stops, key interlock switches)
• LED is located on the switch for door status and fast diagnostics
• High IP69K environmental protection rating
• 3 PNP outputs (including 1 auxiliary)
• Multiple sensing directions offers greater flexibility
• Highly reliable due to short-circuit and over-voltage protection
• Uses the standard proximity brackets

Standards: EN 60947-5-3, IEC 61508, EN 954

The 440N-Z21SS2BN9 interlock switch has a standard code actuator, 18mm assured sensing distance, and a 10m cable. It features a magnetic hold of 9N as well as margin indication. This switch has 2 x PNP safety outputs and 1 x PNP auxiliary output. The rectangular enclosure is made of durable plastic and is red for easier visibility of the unit. This Sensaguard interlock switch is ideally suited for use with hinged, lift-off, and sliding doors.

Rockwell Automation is a global leader in industrial automation and digital transformation, and brings smart manufacturing to life. With a long legacy of creating Allen-Bradley® integrated control and information solutions, we help make you as productive as possible. Our portfolio of sensing, safety and motor control products can support your move towards smart machine applications. Allen-Bradley® IO-Link sensors are data-enabled and communicate with all field buses, providing diagnostic and health information about the device before a machine stops, and enabling quick production changeovers through fast parameter downloads from PLCs into the device. This reduces machine downtime and increases manufacturing OEE. For safety components, products with built-in diagnostics simplify the set-up of the smart device, and reduce maintenance, leading to a more efficient, machine data-driven approach.

RFID stands for Radio Frequency Identification, which is a non-contact method of transferring digital data via radio frequency waves. Equipment with this type of wireless communication usually consist of an RFID tag, an RFID reader, and an antenna. The tag transmits data when triggered by an electromagnetic pulse from the reader. This technology is used widely in many industries, for example with tracking inventory goods, personnel tracking and identification, and restricted area access. Non-contact switches with this technology are highly tamper-proof as they cannot be manipulated, providing a higher level of security.
