Definite-reflective fiber unit combines emitter and receiver in one head, simplifying installation compared with thrubeam setups.
Flat beam emitting direction suits surface detection and installations where the fiber must sit flush against a surface.
2 m fiber length can be shortened to fit the routing distance required in the machine.
Minimum bend radius of R5 mm allows compact cable routing in constrained equipment.
Rated for ambient temperatures from -40°C to +70°C.
