Safety Light curtain Finger Protection

Infra systems, offers new generation Safety Light Curtains / Safety Guards based on advanced micro controller technology. For the same protected height, Cross Beam Light Curtains are more sensitive as there are more number of active beams in the same area.

Ø Safety Light Curtain Finger Protection. – 20mm pitch
