Rotary limit switches

Typically used on cranes, hoists, shiploaders,  and other travelling machines to provide slow-down and stop limit switching in both directions. Replaces 4 conventional limit switches in a single switch, greatly reducing cost and installation time. These rugged switches are extremely popular for long-travel and cross-travel limits on cranes.They can also be used for zone-control (go/no-go areas) for cranes, shiploaders, and other traveling machines.

Worm-drive rotary limit switches

Commonly used on the drums of wire rope hoists, there are countless other applications. The multi-turn input shaft drives a series of 4 adjustable cams through a reduction gearbox. Various reduction ratios available, as well as a range of couplings, and models with secondary output shafts.Often a simple and reliable alternative to shaft-encoders and counters when up to four switch points are needed, and simple adjustment is an asset
