The Pilz PSEN 2.2P-24/PSEN2.2-20/LED/8 MM/ATEX – 503224 is a robust non-contact safety switch engineered for reliable guard and position monitoring in environments where dust explosion hazards are present. With its ATEX approval and compact, durable design, this safety switch combines reliability, compliance, and ease of use to meet the highest standards of operator and machine protection.

A key feature of this model is its ATEX certification (SEV 12 ATEX 0121 X), which qualifies it for use in hazardous areas classified under ATEX Category II 3D Ex mc tc IIIC T80°C. This means it is suitable for industrial environments where combustible dusts may be present, such as food processing plants, grain handling facilities, chemical industries, or woodworking operations. By ensuring compliance with ATEX directives, the PSEN 2.2P-24 provides safe and reliable monitoring even under challenging environmental conditions.

The device operates with a 24 V DC supply and switching voltage, allowing straightforward integration into standard industrial safety control systems. Its 8 mm sensing distance enables precise non-contact monitoring of guard doors, flaps, and protective covers. Non-contact operation significantly reduces mechanical wear compared to traditional switches, leading to longer service life and lower maintenance costs.

Adding to its usability, the PSEN 2.2P-24 is equipped with an integrated LED indicator. This provides clear visual feedback on the switch’s status, allowing operators and maintenance staff to quickly assess functionality and troubleshoot potential issues. The LED feature reduces downtime by enabling immediate detection of alignment problems or faults.

Designed for industrial robustness, the switch is engineered to withstand harsh conditions, ensuring stable performance even in environments with dust, vibration, or frequent machine operation. Its compact design allows easy installation in confined spaces while still delivering reliable monitoring performance.

Typical applications include safeguarding of safety gates, access panels, covers, and hatches in industries where dust-related explosion hazards must be managed safely. With its ATEX approval and diagnostic LED, the PSEN 2.2P-24 is particularly suited for installations where both compliance and operational visibility are essential.

In summary, the Pilz PSEN 2.2P-24/PSEN2.2-20/LED/8 MM/ATEX – 503224 is a specialised safety switch designed for ATEX dust-hazard environments. With its 24 V DC operation, non-contact 8 mm sensing, integrated LED display, and certified ATEX compliance, it provides a reliable and efficient solution for ensuring machine and operator safety in demanding industrial conditions.
