Allen-Bradley 802X-WS17 Limit Switch

The Allen-Bradley 802X-WS17 is a watertight limit switch from Rockwell Automation designed for harsh industrial environments. It features a cat whisker actuator housed in a rugged metal enclosure intended to withstand washdowns and exposure to oil and moisture. The WS17 variant is specified as watertight and is offered in the 802X family with NEMA 4 and NEMA 13 oil-tight protection for indoor use, providing a sealed solution where splash, spray, or damp conditions are present; other members of the 802X line extend to hazardous-location configurations (NEMA 7 and 9) in related models. The switch is designed for reliable mechanical travel sensing and is rated to carry up to 10 A per pole, supporting typical control circuits and moderate industrial loads. Its simple actuation mechanism and robust construction make it suitable for monitoring travel on equipment such as conveyors, processing lines, and other automated machinery that operates in challenging environments. The 802X family is a longstanding line of Allen-Bradley limit switches, and the WS17 designation identifies a specific watertight, cat whisker variant within that lineage.
