The Pilz PSEN1.1B-22/PSEN 1.1-20/8MM/10 M/IX1/1U (part number 504229) is a robust safety switch from the Pilz PSEN series, designed to deliver dependable safety monitoring in industrial environments. With its combination of non-contact technology, wide environmental tolerance, and straightforward integration, this switch is a reliable solution for machine builders and operators who prioritise both safety and efficiency.

Operating at a 24 V DC supply voltage, the PSEN1.1B-22 ensures stable performance in standard industrial control applications. Its 24 V switching voltage provides compatibility with widely used automation and safety systems, making it straightforward to integrate into existing infrastructures. This low-voltage operation reduces electrical risk while maintaining the reliability needed for safety-critical functions.

A notable advantage of this safety switch is its ability to perform in diverse environmental conditions. It operates within an ambient temperature range of –10 °C to +70 °C, covering both cold storage areas and warmer industrial environments. Additionally, the device maintains full functionality up to 2000 m above sea level, demonstrating its robustness in elevated or geographically challenging installations. This resilience makes it suitable for industries such as manufacturing, automotive, packaging, and renewable energy.

The switch is built for durability and versatility. As part of the PSEN series, it uses non-contact safety technology, which eliminates wear and tear associated with mechanical switches. This ensures a longer service life, reduced maintenance needs, and reliable operation even in applications with frequent actuation or vibration. The non-contact principle also enhances system safety by reducing the risk of tampering or mechanical failure.

Installation flexibility is supported by the 10-metre connection cable supplied with the unit. This extended cable length allows the switch to be positioned exactly where it is needed, even in larger systems or machines with decentralised layouts. By reducing the need for additional extensions or connectors, the cable also minimises potential failure points, ensuring consistent signal integrity.

In practical applications, the PSEN1.1B-22 is commonly used to monitor the position of safety gates, covers, or access points, ensuring that hazardous machinery cannot be operated while protective barriers are open. Its robust design and stable operation make it a trusted choice for safeguarding both personnel and equipment.

In summary, the Pilz PSEN1.1B-22/PSEN 1.1-20/8MM/10 M/IX1/1U (504229) is a dependable and versatile safety switch that combines non-contact operation, 24 V DC compatibility, wide temperature tolerance, and extended cable length. Purpose-built for demanding industrial environments, it provides engineers and system designers with a durable, flexible, and standards-compliant solution for machine safety applications.
