4 mm non-flush — the mounting constraint that decides fit
The E2BS08KN04MCB1OMI: The 4 mm sensing distance is specified for non-flush mounting, meaning the sensor face must extend beyond any surrounding ferrous metal by at least the sensing distance itself to avoid false triggering. In a steel bracket, that means the barrel tip needs about 8 mm of clearance from the bracket face. The M8 barrel and M8 connector (3-pin) mate with standard M12 cordsets via an adapter or direct M8 pigtail — the IP67 rating holds only when the mating connector is fully seated and the O-ring is compressed.
PNP NO output and switching speed — PLC input compatibility
PNP normally-open output sources 200 mA at 10–30 VDC, matching standard sinking PLC inputs. The 1 kHz switching frequency means the output pulse width is about 0.5 ms at the rated speed — verify the PLC input filter time constant is set below that to avoid missed edges on fast-moving targets. Current consumption is 10 mA from the sensor itself, leaving the full 200 mA for the load.
Stainless steel housing — washdown and corrosion resistance
The stainless steel barrel resists corrosion from caustic washdown chemicals and food-processing environments better than nickel-plated brass. The IP67 rating covers the sensor body and connector face when mated — the barrel thread itself is not the seal boundary. Operating temperature range is -25 °C to 70 °C, covering most indoor industrial and cold-chain applications.
