The Pilz PSEN CS3.19-OSSD1&2 1 ACTUATOR – 541380 is a precision-engineered safety actuator designed for use with Pilz PSEN CS3 safety switch systems. Together with the associated switch, it provides a non-contact method of safeguarding movable guards, access panels, and machine enclosures, ensuring that machinery is immediately brought to a safe state whenever protective equipment is opened or removed.

As an actuator component, the PSEN CS3.19 does not function as a switch on its own but is paired with the corresponding PSEN CS3 safety switch. Its role is to enable and control the activation of the switch’s dual OSSD outputs (OSSD1 and OSSD2). This redundancy ensures fault-tolerant monitoring and compliance with the highest safety categories, including Performance Level e (PL e) according to EN ISO 13849-1 and SIL 3 under IEC 62061, when integrated into a properly designed safety circuit.

Designed with industrial robustness in mind, the actuator operates within a broad temperature range of -25 °C to +55 °C, maintaining reliable performance in varied conditions such as factory floors, packaging facilities, and light to medium-duty outdoor environments. It also supports installations up to 2000 metres above sea level without loss of rated performance.

In terms of environmental resistance, the actuator is tested according to EN 60068-2-14 (temperature cycling), EN 60068-2-1/-2 (storage standards), and EN 60068-2-78 (climatic suitability). These certifications confirm its ability to withstand mechanical stress, storage conditions, and prolonged exposure to humidity, making it well-suited for demanding industrial applications.

The non-contact operating principle of the PSEN CS3 system reduces mechanical wear compared to traditional keyed or hinged safety interlocks. This results in a longer service life, less frequent maintenance, and reduced downtime—all of which contribute to improved cost efficiency for plant operators. Furthermore, its compact dimensions allow for easy integration into machine frames or protective doors, even where installation space is limited.

Typical applications for this actuator include use with safety switches on sliding or hinged guard doors, access hatches, robotic cells, packaging machines, and material handling systems. Wherever safe access needs to be controlled without compromising efficiency, the PSEN CS3.19-OSSD1&2 provides a proven, reliable solution.

In summary, the Pilz PSEN CS3.19-OSSD1&2 1 ACTUATOR – 541380 is a robust and compact actuator designed for use with Pilz PSEN CS3 safety switches. With its OSSD compatibility, wide temperature range, tested environmental resilience, and maintenance-free non-contact design, it delivers the reliability and flexibility required to keep modern industrial environments safe and productive.
