DI-Soric LR 21 K 4000 P3-K-T4, Retroreflective light barrier O-20, P\n: 207264

The transmitter and receiver are in one housing. The emitted light is reflected back by a reflector and evaluated in the retro reflective sensor. Polarization filters also allow the detection of reflecting objects. Retro reflective sensors make long ranges possible, with simple assembly and a high degree of system availability.

• Long ranges with a small design
• High resolution
• Visible red light with small light spot
• Sensitivity is adjustable
• LED switching status display
• Reflector included
