The Pilz PSEN OP4H-A-30-045/1 (part number 631021) is a compact safety light curtain designed to protect operators working near hazardous machine zones. As part of the Pilz PSENopt family, it offers a balance of precision, reliability, and easy integration, ensuring both safety and productivity in modern industrial environments.

With a resolution of 30 mm and a protective field height of 450 mm, this model is specifically tailored for hand detection applications. Its fine resolution ensures that even small intrusions into the hazardous area are detected, triggering immediate machine stoppage and preventing operator injury. The 450 mm protection height makes it suitable for smaller access points, compact machinery, or applications where partial area safeguarding is required.

The device features two OSSD (Output Signal Switching Device) safety outputs, which provide redundant and independent switching paths. This dual-channel design enhances functional safety, ensuring that faults in one channel do not compromise system performance. The outputs can be directly integrated into Pilz safety relays, controllers, or other safety circuits, supporting compliance with international safety standards such as EN ISO 13849 and IEC 61496.

Optical performance is a key strength of the PSEN OP4H-A-30-045/1. Operating in the 950 nm wavelength range, it delivers stable and reliable detection even in environments with variable lighting conditions. This makes it suitable for use in factories and workshops where ambient light, reflections, or minor obstructions might otherwise impact performance.

The light curtain is powered by a 24 V DC supply, which ensures straightforward integration into standard industrial control systems. Its design also supports energy-efficient operation, allowing continuous use without excessive power demand.

With an operating temperature range of 0 °C to +50 °C, the device is suitable for most indoor production environments, including assembly stations, packaging machinery, and robotic cells. Its robust construction ensures consistent performance under continuous operation, making it a dependable part of any safety system.

Applications for the PSEN OP4H-A-30-045/1 include assembly machines, presses, handling equipment, and semi-automated workstations where operators need protection from hand-level access to hazardous zones. By eliminating the need for physical guards, the light curtain enhances accessibility and ergonomics while maintaining strict safety compliance.

In summary, the Pilz PSEN OP4H-A-30-045/1 is a reliable and compact safety light curtain designed for precise hand detection. With its 30 mm resolution, 450 mm protective field height, dual OSSD outputs, 950 nm optical performance, and compatibility with standard 24 V DC systems, it offers engineers a robust solution for safeguarding operators without reducing efficiency.
