Inductive Sensors

Inductive sensors detect ferrous and non-ferrous metal targets without contact via a damped LC oscillator. Switching occurs when a metal object enters the active face's electromagnetic field. Typical use covers position feedback on cylinders, end-stop detection on conveyors, and tool monitoring in machining centers.

Sensing distances cluster around short-range targets, with 0…3 mm, 1…3 mm, and 2…3 mm being the most common. Versions with extended switching distance cover applications where standard barrel sensors fall short.

Operating temperature is dominated by the -25…+100 °C class with over a thousand devices, followed by -30…+100 °C and -40…+100 °C for outdoor and cold-store use.

Switching frequencies span low-speed targets at 0.25 kHz up to high-speed counting at 800 kHz and 1000 kHz. Cabled variants ship with fixed leads of 2 m, 5 m, or 10 m.

The standard supply is 10…30 VDC, with narrower 20…30 VDC variants for stabilized rails. The assortment also includes IO-Link-capable models for parameterizable diagnostics, plus hygienic stainless-steel versions for food and beverage lines.
