Experience greater dependability, security and safety with the 440N-S32032 Sipha Magnetically Coded Non-Contact Safety Switch by Allen Bradley Guardmaster. This advanced safety switch features magnetically sensitive elements which must be activated in a specific sequence to operate correctly, ensuring superior reliability and security for complex applications. It cannot be defeated by a simple magnet.

To ensure a fully monitored circuit the sensor must be connected to the Sipha control unit. It can provide a high-integrity system for high-risk applications when the control unit is used with a single sensor. It has facilities for connecting a manual reset button and monitoring external devices such as contactors. This unit is ideally suited for use with sliding, hinge, and lift-off safety guards. When the machine guard door is released the power is isolated, preventing dangerous machinery from running while personnel can access it and reducing risk of injury.

The 440N-S32032 Sipha Interlock Switch has S12 housing, 1NC/1NO Safety Contacts and 1NC Auxiliary Contacts. It comes with a 10m cable. This switch offers versatility and simplified installation due to its small size and moulded-in brackets, helping to save you valuable time. The auxiliary output switching is 300V DC, 250V AC, 0.5 A current including inrush. The housing is made of ABS plastic, in red. It is also protected to IP67 (NEMA 6P), making it highly suitable for use in wet environments. It has an operating temperature range of -10 to +55° (+14…+131°). The sensing distance is 5mm (make), 11mm (break).

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.

Non-contact safety switches are low-maintenance and endure less wear-and-tear. They are also resistant to shocks and vibrations, and they cannot be easily tampered with or manipulated. This makes them highly durable and reliable. They are a cost-effective, ideal safety solution for machine guard doors and gates, allowing you to restrict access to hazardous areas where machinery may be in motion. For this reason they are often used in industrial environments.
