Safety Light Curtain for Finger Protection

Minimum space requirement with maximum protection

Safety Light Curtain for Finger Protection

For applications requiring very short safety distances, you can use the Pilz safety light curtains PSENopt and PSENopt II for finger protection. With their fast reaction times, they are ideal for finger protection applications and can be positioned close to the danger point. With its fine resolution, the sensor detects fingers and immediately triggers a safe shutdown command. You can position the safety light curtain very close to the danger zone. Ideal for applications with open intervention areas or where people work directly at the danger zone.

In combination with the Pilz small controller PNOZmulti 2, you have a safe and efficient complete solution for your application – from sensor to control technology, through to risk assessment and declaration of conformity.
