Telco Sensors IPS18-S12NO79-A12 Inductive Proximity Sensor

The IPS18-S12NO79-A12 Inductive Proximity Sensor from Telco Sensors senses metal targets up to 12 mm away, delivering non-contact position and presence sensing in industrial automation and machine control systems. With semi-flush shielded mounting, an NPN normally open output, and a 10–30 VDC supply, it suits conveyor lines, packaging machinery, CNC equipment, material handling, and automated production lines, and is a reliable choice for system integrators. The device draws under 8 mA, switches up to 200 mA, and maintains a voltage drop below 1.5 V at full load, with a 300 Hz switching frequency, repeatability under 1% of distance, and hysteresis between 3% and 15% of sensing distance; it uses a nickel-plated brass housing, a PBT sensing face, and measures 79 mm long with IP67 protection, operating from -20°C to +70°C, plus built-in reverse polarity and short-circuit protections and an integrated LED indicator. Common replacements include IPS18-S12NC79-A12, IPS18-S12PO79-A12, and IPS18-S12PC79-A12.
