With our safety light curtains PSENopt and PSENopt II, you can protect your staff and capital goods – safely, efficiently and economically. An invisible infra-red protected field protects the danger zones and enables optimum access protection. Ideal for production processes requiring active intervention.

Benefit from a wide selection of safety light curtains, complete solutions in combination with Pilz safety controllers and our sound, long-standing expertise in the field of safe automation.

Safety light curtains for safe intervention in the production process

Specifically designed for applications in which material is regularly transported in and out, or where the access point is directly at the danger zone, electrosensitive protective equipment such as safety light curtains enable both safe and flexible intervention in the production process.

Installed on access and intervention points, the safety light curtains PSENopt / PSENopt II monitor the danger zone. If there is a person or object in the protected field, the light beam is broken and a safe shutdown command is triggered immediately. Using the LEDs, the operator can evaluate the main causes of the machine stop and thereby avoid downtimes. Functions such as muting, blanking and cascading open up a wide range of application options.

Pilz light curtains are therefore suitable for numerous industries and applications, such as manual workstations, access guarding on conveyors or material handling alongside robots.

PSENopt – High flexibility for individual requirements

The safety light curtains in the PSENopt series are ideal for use on machines where intervention is required as part of each cycle and they can be used for applications up to PL c (Type 2) and PL e (Type 4). In addition to the Basic light curtains, the PSENopt Advanced safety light curtains offer expanded functionalities such as muting, blanking and cascading. The slimline safety light curtains PSENopt slim have an integrated cascading function and are available for space-critical applications.

PSENopt II – Maximum safety in rugged industrial environments

Flexible application options, fast installation, absence of dead zones and shock resistance of 50g mean that PSENopt II are ideal for use in a rugged everyday industrial environment – even in extreme cold (up to -25°C) or dusty production environments. As well as the first Type 3 safety light curtains, which are suitable specifically for applications up to PL d, you also have Type 4 versions. With their 5-pin connector, they can be connected directly to the decentralised modules PDP67. There are no limits to the physical arrangement of the safety light curtains: thanks to coding, you can even position the light curtain sensors physically close to one another.

Photoelectric sensor – Reliable object detection

The photoelectric proximity sensors enable reliable object detection of a variety of packaging materials. In combination with our safe control technology, you can safely monitor the cardboard feed.
