Product Description

The IFM DI5004 is a compact speed monitoring unit designed to detect and evaluate rotational and linear movements, ensuring reliable underspeed and blockage detection in industrial applications. Featuring a PNP output with a normally open function, it operates within a sensing range of 10 mm and is adjustable via a multiturn potentiometer. The device supports a wide operating voltage range of 10–36 V DC and offers robust protection with an IP67 rating, making it suitable for harsh environments. Its brass housing with a special coating and PBT material ensures durability, while the integrated LED indicator provides clear switching status feedback.​
