The Pilz PSEN SL-1.0 2.1 1 Actuator (Part Number: 570621) is a safety switch with guard locking, designed to provide effective protection for operators and equipment in industrial automation. As part of the PSEN safety switch family, this device ensures that access to hazardous machine areas is securely controlled, preventing premature entry until dangerous movements have ceased.

At its core, the PSEN SL-1.0 2.1 operates as a guard locking actuator, working in tandem with machine safety control systems to prevent unintended access. When integrated into protective enclosures such as safety doors, gates, or hoods, it guarantees that hazardous energy sources remain locked until it is safe to disengage. This functionality is critical in industries where machinery continues to pose a risk after stop signals are issued, such as in robotics, conveyor systems, or rotating machinery.

The device is built to endure harsh environmental conditions, complying with international standards including EN 60068-2-14 for temperature variations, EN 60068-2-1/-2 for storage requirements, and EN 60068-2-78 for climatic suitability. It operates effectively in ambient temperatures ranging from -25 °C to +55 °C, making it suitable for use in both refrigerated and heated industrial environments. Additionally, its proven performance at 93% relative humidity (at 40 °C) ensures reliable operation in areas prone to condensation or fluctuating humidity levels.

With its compact design, the PSEN SL-1.0 2.1 1 Actuator is easy to integrate into control panels and machine frameworks without requiring extensive space. This makes it an ideal solution for both new installations and retrofit projects, where flexibility and efficiency are crucial. Its robust construction ensures a long service life, reducing downtime and maintenance costs while delivering continuous protection.

As part of a complete Pilz safety architecture, the PSEN SL-1.0 2.1 can be combined with safety relays or PNOZmulti configurable controllers to deliver comprehensive safety coverage. This ensures compliance with global machine safety regulations, giving manufacturers confidence in meeting legal requirements while protecting personnel.
