IFM IG6086 Inductive Analogue Sensor

The IFM IG6086 is a precision-engineered inductive analogue sensor designed for reliable object detection and accurate distance measurement in industrial environments. Featuring a threaded M18 housing with flush mounting capability, the IG6086 offers a measuring range of 0.5 to 5 mm, a fast response time under 10 ms, and parameterisable PNP/NPN outputs alongside a linear 4–20 mA analogue output. Its IO-Link communication, rugged brass housing with white bronze coating, and extensive EMC and shock resistance certifications make it ideal for demanding automation and sensing applications.
