4 mm unshielded — what fits where
The E2E-S04N02-WC-B1: The 04 code in the part number means a 4 mm outer diameter barrel — this is a true sub-miniature form factor, not a standard M8 or M12. The unshielded (N) variant means the sensing field extends beyond the barrel face without a metal band, giving the full 2 mm sensing distance on mild steel. Output is DC 3-wire PNP normally open, so it sources a positive signal to the PLC input when a target enters the 2 mm window. The PVC pre-wired cable (WC) saves a connector — just route and terminate, no mating half to buy.
