Inductive Proximity sensors Principle

Inductive sensors detect metallic objects at an operating distance of up to 50mm. They are insensitive to external influences and are durable for all applications. They offer high speed, no contact sensing with an extremely long life.

Basic Mode of Operation:

The essential component of the inductive sensors is its oscillator with open coil. When a metallic object approaches the sensor, the oscillation is initially attenued and ultimately interrupted. This effect is detected by a trigger circuit and is forwarded as an output signal
