Schmersal Non-Contact Door Handle Safety Switch, 24V DC, Coded - BNSB20 Series - BNS-B20-12zG-ST-R
Keep operators safe around moving machinery with this door handle safety switch from Schmersal. When a machine guard opens, the switch automatically breaks the circuit to protect personnel against potential hazards. When the guard is secured, the switch restarts the circuit and the machine resumes normal operations. The switch has a wide operating temperature range of -25°C to +70°C, so it's suitable for use in hot or cold environments. Its non-contact operation ensures minimal wear for an enhanced service life.
