The Pilz PSEN OP67-69K-105/1 is a versatile safety light curtain designed to provide dependable protection for operators working with automated machinery. As part of Pilz’s trusted PSENopt series, this model ensures that hazardous zones remain secure by forming an invisible, monitored barrier of infrared beams. When the beam field is interrupted, the curtain immediately triggers a safe machine stop, protecting personnel without impeding productivity.

Engineered with a protection class of IP67 and IP69K, the PSEN OP67-69K-105/1 is fully resistant to dust ingress, water spray, and even intensive high-pressure washdowns. This makes it particularly well-suited for industries where hygiene and frequent cleaning are essential, including food and beverage manufacturing, pharmaceuticals, and packaging. Its resilience against harsh conditions ensures consistent performance and long service life, even in environments subject to moisture and chemical exposure.

The housing is made from PMMA (polymethyl methacrylate), a material renowned for its strength, transparency, and resistance to stress. This ensures optimal beam transmission and reliable operation, while also offering mechanical durability in industrial environments where impact and vibration are common.

With a height dimension of 1278.5 mm, this model provides a medium coverage field, making it ideal for safeguarding mid-sized openings, production cells, or operator access points. It strikes the right balance between compact models used for smaller machinery and taller variants designed for large installations. The protective field ensures that any interruption to the light beams immediately halts machine activity, preventing accidental access to hazardous areas.

The solid build of the PSEN OP67-69K-105/1—evident in its net weight of 2150 g (gross 2680 g)—underscores its industrial-grade design. This ensures stable installation and reliable operation, even in demanding environments where equipment operates continuously.

Integration into automation systems is straightforward, particularly when paired with Pilz controllers and safety relays. The device’s fast response time guarantees that machinery is brought to a safe condition instantly upon beam interruption, delivering reliable protection without compromising operational efficiency.

In summary, the Pilz PSEN OP67-69K-105/1 safety light curtain offers medium-height safeguarding with high durability and environmental resistance. Its IP67/IP69K protection, PMMA housing, and 1278.5 mm protective field make it an excellent choice for industries requiring robust, hygienic, and dependable operator protection in automated production environments.
