Comparison of sensing ranges with non flush proximity switches

Benefits introduce In Detail

Extended sensing range reduces failures caused by mechanical damage

ifm’s inductive proximity switches perfectly combine function, performance, and value. They use a unique design with smaller temperature drift and a wider operating temperature range, improving the sensing range tolerance to ±5%.

These proximity switches are resistant to shock, vibration, and electrical noise. With a protection rating up to IP68/IP69K, they can prevent water ingress and withstand oil and coolants in harsh applications.

ifm’s all-new proximity switches have an extended temperature range and can be installed further away from the target, thereby preventing damage from physical impact.
