SC-2020B Proximity Switch Product Description

The SC-2020B is an inductive proximity switch designed for industrial automation applications. It operates on the principle of electromagnetic induction to detect metallic objects without physical contact. With a standard sensing distance of 20mm (±10% tolerance) and adjustable activation range up to 17mm, this device features a brass nickel-plated housing with ABS sensing surface, providing resistance to vibration and corrosion. The switch supports both AC two-wire (110-220V) and DC configurations, offering NO/NC output options. Its compact design and IP67 protection rating ensure reliable performance in harsh environments including temperature ranges from -30℃ to +65℃.18218
