Connection is via a male M12 4-pin connector, which is the standard quick-disconnect for photoelectric sensors in industrial automation — no hardwiring required, just plug and tighten. The supply range covers 24 V DC nominal, so it drops into existing 24 V control circuits without a separate regulator. The M12 male connector makes panel integration straightforward: mates with standard M12 female cordsets, 4-pin, A-coded. The PNP output is sourcing — typical for SICK sensors feeding into PLC input modules that expect a positive-switched signal. The 100 mA output current drives small relays or indicator lamps directly, though for larger loads you'd buffer through an interposing relay.","metaTitle":"SICK WT12-P4181 Photoelectric Sensor, PNP, 10-30 V DC","metaDescription":"SICK WT12-P4181 photoelectric sensor, PNP output, 10-30 V DC supply, max 100 mA, M12 4-pin connector.
