The Turck NI20NF-CP40-VP4X2 is a selective inductive proximity sensor designed to detect only non-ferromagnetic metals (aluminum, copper, brass) while ignoring steel and iron. Using Turck's uprox technology, it provides 20mm rated sensing distance in a non-flush CP40 rectangular housing (114×40×40mm). The 4-wire PNP complementary output (NO+NC) operates from 10-65 VDC at up to 200mA with IP67/NEMA 4/6/13 protection. The active face can be oriented in 9 directions for flexible mounting. Applications include aluminum part detection on automated assembly lines, non-ferrous material sorting, copper/brass component presence sensing, and selective metal detection in recycling and packaging industries.
**Q: Will the NI20NF-CP40-VP4X2 detect steel objects?**
A: No. The "NF" designation means it selectively detects only non-ferromagnetic metals (aluminum, copper, brass, etc.) and ignores ferrous metals like steel and iron. This is the opposite of standard inductive sensors.
**Q: Can the active face be rotated for different approach directions?**
A: Yes, the CP40 modular design allows the active face to be oriented in 9 different directions, providing flexible mounting options.
