Pilz — Safety Relays

Pilz PNOZ X2 Safety Relay

The Pilz PNOZ X2 is a classic electromechanical safety relay providing failsafe switching for emergency stop circuits, guard door interlocks, and safety mat monitoring. With three normally open (N.O.) safe output contacts and one normally closed (N.C.) auxiliary contact, it directly switches loads up to 8 A per channel without external contactors in many applications. The relay monitors dual-channel input circuits with cross-fault detection and requires a manual reset after each safety-demand event, ensuring controlled machine restart per ISO 13849-1 requirements. Its 22.5 mm housing saves significant panel space in multi-relay cabinets, and the tool-required terminal screws prevent unauthorized circuit modification. The PNOZ X2 is the industry reference standard for basic safety switching, with decades of field-proven reliability in countless machine safety installations across South Africa and worldwide.
