TER Position Limit Switches

TER Position Limit Switches — Linear Travel Limit Control for US Overhead Crane and Hoist Applications

TER position limit switches provide precise control for hoists, winches, and other industrial applications, ensuring safe operation by preventing over-travel. Where TER rotary limit switches mount to a rotating shaft and measure angular rotation, TER position limit switches are physically actuated by contact with a moving machine component — a crane bridge, trolley, hoist hook block, or runway stop — triggering a switching action at a defined physical position along the travel path. OSHA 1910.179(g)(5)(iv) requires that the hoisting motion of all electric traveling cranes be provided with an overtravel limit switch in the hoisting direction — and TER position limit switches are the standard electromechanical solution for satisfying this requirement across US overhead crane and hoist installations.

Crane-Controls.com stocks three TER position limit switch categories for US crane and hoist applications — DIN Limit Switches, Standard Limit Switches, and Cross Limit Switches — covering the full range of physical travel limit and end-of-travel protection requirements encountered across US overhead crane, hoist, monorail, and industrial machinery installations. All TER position limit switches feature positive opening NC contacts for safety functions, wear-resistant internal components, and water and dust resistant construction for reliable performance in demanding US industrial crane environments.

Crane-Controls.com's technical team provides pre-sale application support for TER position limit switch selection and application specification for US crane and hoist installations. OSHA 1910.179, CMAA, and ASME B30 compliant installations supported across the full TER position limit switch range.
