E2A-M12KS04-M1-B1 Inductive Proximity Sensor Switch, 12-24VDC DC 3-Wire PNP-NO, M12 Threaded Cylindrical Shielded 4mm, 4-Pin M12 Connector, 200mA Load, for Industrial Automation, Replacement

Inductive Proximity Sensor (OE#E2A-M12KS04-M1-B1)This listing is for an inductive proximity sensor replacement identified by OE number E2A-M12KS04-M1-B1. Please verify fitment by OE number and your equipment manual/datasheet before ordering.Key Specs (verify against your manual)Power supply: 12–24 VDC (operating range 10–32 VDC)Output: DC 3-wire, PNP open collector, NO (normally open)Sensing distance: 4 mm (shielded type)Connection: M12 connector, 4-pin (Pin 4 not used per datasheet)Max load current: 200 mA (32 VDC max)Function & Typical IssuesNon-contact detection of ferrous metal targets for presence/position sensing.Possible symptoms of a failing sensor: no output, intermittent detection, reduced sensing distance, or unstable switching.Installation NotesTurn power OFF before wiring or replacement.Confirm polarity and pinout; do not apply AC voltage to DC models.Use a proper load and avoid load short-circuit conditions.Mount securely (e.g., M12x1 threaded hole or matching bracket/hole) and keep the sensing face clean.Fitment reminder: Confirm fitment by OE number (E2A-M12KS04-M1-B1) / equipment manual. Do not rely on appearance alone.

• Specs: 12–24VDC power supply (10–32VDC operating range), DC 3-wire sensor, PNP open collector output, NO (normally open). M12 shielded cylindrical proximity sensor with 4 mm sensing distance; short-body brass-nickel housing and gold-plated pins. Connection: M12 connector (4-pin; Pin 4 not used per datasheet). Max load current: 200 mA (32VDC max). Main OE reference: E2A-M12KS04-M1-B1. Use for non-contact presence/position detection on ferrous metal targets; verify match by OE number.
• Install/replace with power OFF. Confirm your supply polarity and wiring before energizing; do not apply AC voltage to DC models. For M12 4-pin plug-in wiring, follow the pin arrangement and note the unused pin (per datasheet). Mounting options typically include an M12x1 threaded hole or a 12 mm mounting bracket/hole—match your machine’s mounting hardware. Set proper sensing/setting distance, keep the sensing face clean (metal chips can affect detection), and re-check switching after installation. Confirm fitment by OE number / equipment manual before purchase.
• Compatible with industrial equipment requiring a 12–24VDC DC 3-wire PNP-NO inductive proximity sensor, M12 shielded 4 mm sensing distance, M12 4-pin connector (Pin 4 not used), machine frame/bracket mount sensor replacement. Confirm fitment by OE number (E2A-M12KS04-M1-B1) or equipment manual.
• Often used with PLC/digital input modules, sensor extension cables, and terminal blocks. Choose matching PNP input type, voltage range, and connector style to avoid signal mismatch. If replacing multiple sensors, keep the same sensing distance (4 mm) to maintain consistent machine timing and detection repeatability.
