The Pilz PSEN SL-1.0 1.1 Actuator (Part No. 570620) is a purpose-built actuator for safety switches with guard locking, designed to provide dependable position detection and secure operation in industrial safety systems. As an integral component of the Pilz PSEN safety range, this actuator ensures that protective doors, guards, and access points are reliably monitored and locked to prevent accidental access to hazardous machine zones.

Engineered for environmental resilience, the PSEN SL-1.0 1.1 is certified to meet international testing standards, including EN 60068-2-14 for temperature cycling, EN 60068-2-1/-2 for storage temperature conditions, and EN 60068-2-78 for climatic suitability. These certifications confirm the actuator’s robustness and ability to function consistently under demanding industrial conditions.

The actuator operates across a wide ambient temperature range of -25 °C to +55 °C, making it suitable for environments subject to both cold and heat extremes. This broad range ensures reliable performance in industries such as food processing, automotive, packaging, and heavy manufacturing, where varying temperatures are common. In addition, the actuator’s storage temperature resilience ensures it remains fully functional even after long periods of storage or transport under fluctuating conditions.

Another key advantage is its resistance to high humidity levels, rated for up to 93% relative humidity at 40 °C. This ensures dependable operation in environments where condensation or elevated moisture levels may otherwise compromise performance. Such resilience makes it suitable for industries that require frequent cleaning, operate in damp environments, or face seasonal variations in climate.

The PSEN SL-1.0 1.1 is designed specifically to work with Pilz guard locking safety switches, providing a secure interlock between the actuator and the switch. When integrated into a machine safety circuit, the actuator ensures that hazardous functions are immediately disabled when protective guards are opened, preventing operators from entering dangerous areas while machinery is in motion. By enabling secure locking and monitoring, it plays a crucial role in protecting personnel from injury and ensuring machines meet international safety compliance requirements.

Compact and easy to integrate, the actuator is straightforward to install on machine doors, hatches, or safety guards. Its durable build guarantees long service life with minimal maintenance, making it a cost-effective solution for machine builders and plant operators alike.

In summary, the Pilz PSEN SL-1.0 1.1 Actuator (570620) combines robust guard-locking functionality, environmental resilience, wide temperature tolerance, and high humidity resistance. As part of a Pilz safety system, it ensures reliable access monitoring, operator protection, and compliance with international safety standards in demanding industrial environments.
