Omron XS2F-D421-D80-A | M12 4-Pin Female Straight Sensor Cable — 2 m PVC / 250VDC / 4A / IP67 / Single-Ended

M12 Quick-Connect for Industrial Proximity Sensors

The XS2F-D421-D80-A is a pre-wired M12 sensor cable — a 2-metre PVC cable with a 4-pin M12 female (socket) connector on one end and bare flying leads on the other. It connects between an M12-equipped proximity sensor and the control panel or junction box, providing the quick-connect field interface that the M12 standard was designed for.

M12 4-pin A-coded connectors are the standard interface on a broad range of industrial proximity sensors, including Omron's E2E, E2E2, and E2EW series cylindrical proximity sensors. 

The female socket on this cable mates directly with the male M12 connector fitted to these sensors at the factory — no field wiring of the sensor connection is required.

The bare flying leads at the panel end connect to PLC input terminals, junction boxes, or terminal strip in the control cabinet. Standard 4-wire sensor colour coding (brown = V+, blue = 0V, black = signal output, white = additional signal or not connected) is used on the flying leads.

Key Specifications

PVC Standard Cable vs Fire-Retardant Robot Cable

The -A suffix on the XS2F-D421-D80-A identifies standard PVC cable — as opposed to the -F suffix variants (XS2F-D421-D80-F) which use fire-retardant PVC robot cable rated for use in robot trailing cable applications with repeated flexing, high-cycle movement, and applications requiring fire-retardancy certification.

For fixed installation where the cable does not flex repeatedly — sensor mounted on a static machine structure, cable routed in conduit or cable duct — the standard PVC cable of the -A variant is appropriate. For applications on moving arms, robot peripherals, or installations where fire-retardancy is required by the facility or safety specification, the -F variant is the correct selection.

FAQ

Q1: What proximity sensors is the XS2F-D421-D80-A compatible with?

Any M12 proximity sensor with a 4-pin A-coded male connector — including Omron E2E, E2E2, E2EW, and related cylindrical proximity sensor series. The M12 4-pin A-coded connector is also used by many third-party proximity sensor manufacturers, making this cable compatible with most standard industrial proximity sensors of this form factor.

Q2: What is the wire colour coding on the bare lead end?

Standard M12 4-pin sensor wiring colour convention: brown (pin 1) = positive supply (V+), blue (pin 3) = negative supply / 0V, black (pin 4) = output signal (NPN or PNP depending on sensor), white (pin 2) = not connected or second output signal. Confirm the specific colour assignment against the sensor's documentation before connecting — some manufacturers use different conventions.

Q3: What is the difference between the -A and -F suffix variants?

The -A suffix (this cable) uses standard PVC jacket — suitable for fixed cable routing in static installations. The -F suffix uses fire-retardant PVC robot cable, designed for dynamic flexing applications (robot trailing cables, moving cable carriers) and for installations requiring fire-retardancy certification. Both carry the same electrical ratings and M12 connector; the difference is cable material and mechanical flexibility specification.

Q4: Is the M12 connector end waterproof?

The M12 connector is rated IP67 when mated to a compatible M12 male connector. IP67 means the mated joint withstands temporary immersion in up to 1m of water. The connector must be fully mated and locked — a partially engaged connector does not provide the IP67 rating. The cable itself and the bare flying leads end are not independently rated to IP67.

Q5: What length variants are available in the XS2F-D421 series?

The XS2F-D421 series is available in multiple cable lengths, identified by the letter code in the part number: C = 1m, D = 2m, E = 3m, G = 5m, J = 10m, K = 15m, L = 20m. The suffix (-A or -F) then identifies the cable type. Select the length based on the distance between sensor mounting point and panel entry point, with some margin for routing.
