Proximity switch selection for different materials and different sample detection distance, should use a different type of proximity switch, so that it has a high cost performance in the system, for which the selection should follow the following principles: 1.1. When the sample when the metal material should be used in high-frequency oscillation type proximity switch, the proximity switch type nickel-iron, A3 steel sample to detect the most sensitive category. Aluminum, brass and stainless steel type specimen, the detection sensitivity is low. 1.2 When a sample is non-metallic materials, such as; timber, paper, plastic, glass and water should be used in capacitive proximity switch. 1.3. When the metal body and non-metallic to conduct long-range detection and control should be used in photoelectric proximity switch or ultrasound proximity switch. 1.4 For a sample of the metal magnetic switch schneider, if the detection sensitivity is less demanding, the choice of inexpensive magnetic proximity switch or Hall proximity switches.
