Explosion-Proof Photoelectric Beam Sensor TAKEX PXH-100EX
- Explosion-Proof Photoelectric Beam Sensor, 100m, double modulation, Class I & II hazardous location.
- Long-distance beam sensor for outdoor use equipped with intrinsically safe explosion-proof structure which can be used in hazardous areas of Class 1 (Zone 1) and Class 2 (Zone 2).
- Two types of the product ('L” and “H”) with different frequencies available for mutual interference prevention in case of multi-level protection and long straight line protection.
