Delock Fork Light Barrier 5 mm Type U with 4 Open Cable Ends NPN L/D Switchable 2 m

Fork photoelectric sensor with a 5 mm gap, delivering high-speed through-beam detection with NPN open collector output and switchable Light-ON/Dark-ON logic. Its robust PBT housing and IP67 rating ensure reliable operation in demanding industrial environments.

Advantages

The compact fork design simplifies mounting and alignment, while the 5 kHz switching frequency and <0.1 ms response time enable precise detection of fast-moving objects. The L/D switchable output provides flexibility for integration into various control systems, and the short-circuit and reverse polarity protection enhance durability.

Suitable for

• Object detection in assembly lines and packaging machines
• Edge detection for printing and labeling equipment
• Position verification in automated handling systems
• Counting and sorting applications in material handling
