Pilz PSEN 2.1 Magnetic Safety Switch 1NO 1NC 24V DC

The Pilz PSEN 2.1 magnetic safety switch is a robust solution engineered for the precise position monitoring of safety guards in industrial environments. Operating on a 24V DC power supply, this device utilizes non-contact magnetic technology to detect the status of doors, flaps, and protective covers. By integrating 1NO and 1NC contacts, it provides a reliable feedback signal to safety controllers, ensuring that machinery remains in a safe state during operation.

Advantages

The primary benefit of the Pilz PSEN 2.1 is its non-contact operating principle, which eliminates mechanical wear and tear, significantly extending the service life of the sensor. Its design is highly resistant to vibration and environmental contaminants, ensuring consistent performance even in demanding industrial settings. The compact housing allows for flexible installation in tight spaces, while the magnetic sensing technology offers a high degree of protection against tampering, contributing to a safer workplace.

Suitable for

• Monitoring safety gates and sliding doors
• Securing protective flaps and machine covers
• Industrial automation and robotics safety systems
• Applications requiring high reliability in harsh environments

When it may not be suitable

This magnetic safety switch may not be suitable for applications involving extremely high temperatures or environments with strong external magnetic fields that could interfere with the sensor's operation. It is also not intended for use in explosive atmospheres unless specifically rated for such conditions.

Key specifications

• Contact configuration: 1NO and 1NC
• Operating voltage: 24V DC
• Technology: Non-contact magnetic sensing
• Housing type: Compact safety switch

How to use

Installation involves mounting the sensor and the corresponding actuator on the fixed and moving parts of the safety guard, respectively. Ensure that the alignment is within the manufacturer's specified tolerances to guarantee proper magnetic coupling. Once mounted, connect the 1NO and 1NC contacts to your safety relay or programmable logic controller. Verify the switching function by opening and closing the guard to ensure the safety circuit responds correctly before putting the machine into full operation.

What to consider before purchase

• Compatibility with your existing safety control system
• Required mounting distance and alignment tolerances
• Environmental conditions of the installation site
• Compliance with local safety regulations and standards

Usage recommendations

Regularly inspect the sensor and actuator for any physical damage or accumulation of metallic debris. Periodically test the safety function to ensure the system triggers a stop command when the guard is opened.
