Industrial SI12-C2PNP Inductive Proximity Switch

The AECO SI12-C2PNP inductive proximity switch is a compact, non-contact sensor designed to detect metal targets within a 2 mm switching distance, powered from 10–30 V DC with a PNP output. The SI12-C2PNP version features a 2 mm switching distance Sn, with a real sensing distance Sr of 2 mm ± 10% and an operating distance So of 0 to 1.62 mm, enabling precise position sensing in tight spaces. Electrical specs specify a supply voltage of 10–30 V DC, current consumption under 15 mA at 24 V, a maximum output current of 200 mA, and a switching frequency up to 1,000 Hz, with short-circuit protection built in. The device is rated for industrial environments with IP65, IP66, and IP67 protection ratings and an operating temperature range of -25 to +70 °C. The SI12-C2PNP designation places it in the C2 family with PNP logic, a configuration commonly used for automation tasks requiring non-contact metal detection. This sensor provides robust, relay-free switching suitable for direct interfacing with PLC inputs and other control electronics in manufacturing and machine automation.
