SICK WT12-P4471 Photoelectric Proximity Switch

The SICK WT12-P4471 Photoelectric Proximity Switch is a member of SICK’s WT12 family and is designed for reliable object presence detection in tight spaces across manufacturing and packaging environments. It operates from a 10 to 30 V DC supply and draws up to 100 mA, delivering a PNP-type switched output that interfaces with standard PLC inputs and automation modules. The device typically ships with a 4-pin M12 connector, aligning with common fieldbus and sensor cabling practices used on WT12 variants, and is referenced in multiple retailer listings by its exact part number WT12-P4471. In catalog listings, the WT12-P4471 is identified as discontinued by the manufacturer, so buyers should verify current availability and consider suitable in-family replacements when planning maintenance or upgrades. As with other optical proximity switches in this line, the WT12-P4471 is intended for non-contact object sensing in environments where compact sensors and rugged operation are preferred.
