The Pilz PSEN CS2.1N 1 SWITCH – 540153 is a non-contact safety switch designed for monitoring protective devices such as safety gates, doors, and covers. As part of the proven PSEN CS series, this compact and durable switch ensures operator protection and machine safety by preventing access to hazardous zones until the system is in a safe state.

Engineered for simplicity and reliability, the PSEN CS2.1N operates with a 24 V DC supply voltage, making it directly compatible with modern industrial control systems. Its low power consumption of just 2 W ensures energy efficiency, particularly important in production environments where multiple safety devices are used simultaneously.

The switch is equipped with two OSSD (Output Signal Switching Device) outputs, designed for fail-safe signal transmission to connected safety controllers or relays. OSSD technology continuously monitors the outputs, detecting cross faults, shorts, or wiring errors. This ensures that if a fault occurs, the system automatically transitions into a safe state, preventing hazardous machine operations.

Unlike some other models in the series, this version does not include potential isolation between supply and outputs, which simplifies wiring and reduces installation complexity. It is intended for direct integration into safety systems where shared potential designs are acceptable.

The PSEN CS2.1N’s compact housing makes it suitable for installations with limited space while maintaining robust performance. Its non-contact operating principle eliminates mechanical wear, extending service life and reducing the need for maintenance. This makes it particularly advantageous in high-cycle applications where doors or guards are opened frequently.

Typical applications include monitoring access doors, swing gates, sliding guards, and removable panels on machinery in industries such as packaging, food and beverage, robotics, and general manufacturing. By ensuring that hazardous machine functions cannot be initiated until guards are closed and locked, the switch protects operators while supporting compliance with international safety standards.

Integration with Pilz safety controllers, such as PNOZ relays or PNOZmulti configurable control systems, allows the switch to be part of a comprehensive safety architecture. This ensures flexibility, scalability, and complete compliance with machine safety requirements.

In summary, the Pilz PSEN CS2.1N 1 SWITCH – 540153 provides compact, efficient, and reliable safety monitoring with dual OSSD outputs and low power consumption. Built for long-lasting performance in industrial environments, it is a practical and effective choice for safeguarding operators and machinery while maintaining high productivity levels.
