Where it helps
Selection and installation checklist
- Verify that NPN normally open logic matches the connected controller input.
- Use the 2 mm non-flush version with the specified 12 x 12 x 1 mm standard iron target.
- Check that the target is magnetic metal; non-magnetic metal reduces the detection distance.
- Confirm supply voltage, protection class, connection type, wiring, and selected output configuration with XSZ before order.
