Turck NI4-M12-AP6X Inductive Proximity Sensor

The TURCK NI4-M12-AP6X Proximity Sensor provides non-contact detection of metallic targets with a 4 mm sensing distance. Housed in chrome-plated brass with an M12 x 1 threaded barrel, this non-flush mount sensor is rated IP67 and is designed to withstand industrial environments. It operates on 10–30 VDC and delivers a 3-wire PNP output with a normally open contact, enabling straightforward connection to PLC inputs. A 10 m cable accompanies the unit, supporting longer-range wiring in automated lines where space constraints or routing require extended cables. With a switching frequency of up to 2 kHz, it offers reliable metal-object sensing for fast-moving equipment. Common applications include CNC machines, conveyor systems, material handling, packaging equipment, robotics, and other manufacturing lines where precise metal detection and position sensing are essential. This model is part of TURCK's NI4-M12 family, and there are common replacements such as TURCK NI4-M12-AP6X-H1141, Pepperl+Fuchs NBB4-12GM50-E2-V1, and IFM IFS204 for similar inductive proximity sensing needs.
