Ratings and fit
The XS7C2A1MAU20: Supply voltage covers both AC and DC from 24 to 240 V, so a single part number can serve panels with different control voltages—reduces BOM line count. The 2-wire NO circuit simplifies wiring (two conductors, no auxiliary supply) but watch for voltage drop across the sensor when driving a PLC input; the off-state leakage for a 2-wire AC/DC sensor can be up to a few mA, which might not pull a standard input low. Shielded sensing face means flush mounting in metal is fine—no derating needed for embedment. Body dimensions are 40 x 40 x 70 mm (W x D x H). The 1/2-inch connector (industry standard for this size) mates with common quick-disconnect cables. Green LED indicator gives a clear on-target signal for commissioning and troubleshooting—no need to break the loop to check output state.
Sourcing note
Because the XS7C2A1MAU20 is an active, standard-catalog part, it can be quoted to order against an RFQ with normal lead times. No broker or surplus risk—this is a part the factory is still producing. For a BOM freeze, confirm the exact connector mating and cable length requirements; the sensor itself is fixed.
