Features: Proximity switch, also known as contactless proximity switch, is an ideal electronic on-off sensor. It has sensing performance, reliable action, stable performance and fast frequency response. Shockproof, corrosion resistance, strong anti-interference capability. Non-contact detection, does not affect the operating conditions of the measured object. Sealed structure, good moisture and dust resistance, strong work reliability. No mechanical wear and fatigue damage, long working life. Widely used in machine tools, metallurgy, chemical, textile and printing industries.
