The ICB series of four-wire complementary output inductive proximity sensors includes a normally open and normally closed output in the same package. Sensors are offered in short or long barrel, flush or nonflush mounting and NPN or PNP type. Features include an M12 plug for quick disconnect or 2-m prewired cable, standard or extended sensing distances (reaching up to 22 mm), integrated diagnostics LED, IP67 rating to protect against water and humidity penetration, built-in microcontroller for accurate and repeatable operation and conformance to global standards such as UL 508 and IEC 60947-5-2.
