Active production — BOM-fit for M12 unshielded sensing
The E2B-M12KN08-WP-B1 2M: The Omron E2B-M12KN08-WP- 2M is an active-production inductive proximity sensor from the E2B series, listed under the Interface & Transceivers category. Rated for an 8 mm sensing distance on mild steel (unshielded mount), the sensor detects ferrous targets through a non-metallic wall or in free space — the unshielded construction gives a longer range than a shielded equivalent at the same M12 barrel size. The correction factor for stainless steel is roughly 0.7×, so budget 5–6 mm in a stainless target application.
Output, supply, and environmental envelope
PNP-NO, 3-wire output — the sensor pulls its output high when a target enters the 8 mm detection zone. The 10 V supply voltage (nominal, typically 10–30 VDC range) powers the internal oscillator and LED indicator. Switching frequency is 800 Hz, adequate for conveyor belt counting, part-present detection, and general machine automation at moderate line speeds. IP67 rating means the sensor body and cable entry withstand washdown and temporary immersion — suitable for food-and-bev lines, outdoor conveyor systems, and wet machining centres. The nickel-plated brass housing resists corrosion in industrial atmospheres. Operating temperature spans -25°C to 70°C, covering most factory-floor and outdoor cabinet environments.
Sourcing and cross-reference note
The shielded peer E2B-M12KS04-WP- 2M offers a 4 mm sensing distance with a shielded barrel — use it when flush mounting in metal is required. The unshielded 8 mm version here is the right choice for non-flush or through-wall detection where maximum range is the priority.
