Hekatron ORS-142-EX Optical Smoke Switch (5000590-0201)

The Hekatron ORS-142-EX (5000590-0201) Optical Smoke Switch works on the principle of scattering light. A light source and light sensor inside the sensing chamber are arranged in a way that light normally does not reach the sensor. Only when particles are suspended in the air, light is scattered on the receiver. The evaluation electronics in the ORS-142-EX monitors the smoke component of the sensor for mild contamination, serious fouling and for faults. The optical indicator shows the current operating status of the ORS-142-EX.
