IFM IFC/IGC/IIC Series Inductive Proximity Sensor Switch

Technical Features

Extended sensing range increases the distance between the proximity switch and the target, thereby extending uptime.

Models with a rugged 316 stainless steel housing can withstand corrosive oils and coolants.

Optional models with an anti-chip ceramic sensing face are available.

K=1 sensor technology provides the same sensing range for all target materials.

Industry-standard M12 Micro DC connector.

Benefits introduce In Detail

Robust proximity switches resistant to oil and coolants

Oils and coolants used in metalworking applications can penetrate the housing of proximity switches, leading to component failure and fluctuations in the sensing range. Through research and experience, it has been found that industry-leading companies use a wide variety of oils and coolants.

ifm’s proximity switches are fully immersed in these oils and coolants at a temperature of 80°C. By measuring the sensing range after prolonged exposure in the test chamber, the zero-leakage design of the proximity switches was verified. The sensing range of these proximity switches did not change at all, and thus they passed the test.

Correction factor K=1 sensor technology

Depending on the target material, standard proximity switches have a sensing range correction factor. For example, the sensing range for an aluminum target is 60% smaller than for a mild steel target. Proximity switches using K=1 technology have the same correction factor for all metals. Therefore, these proximity switches have the same sensing range for both aluminum and steel targets.
