Pull Rod Linear Position Sensor

Shanghai Zhaohui Pressure Apparatus Co., Ltd. is one of the leading manufacturers and suppliers of pull rod linear position sensor in China, also supports customized service and 1 year warranty. Welcome to wholesale bulk durable pull rod linear position sensor in stock here from our factory.

This externally mounted pull rod linear position sensor translates mechanical linear motion via a spring-retracted or captive stainless-steel rod connected to a wiper or core moving along a resistive, inductive, or magnetostrictive element. The pull rod linear position sensor's fundamental strengths lie in simplicity, passive operation (no onboard active electronics), and direct analog output (voltage divider or Wheatstone bridge). The rod's pivoting eyelet or threaded tip accommodates minor angular misalignment between moving and fixed machine parts. Typical response time is sub-millisecond, offering virtually infinite resolution limited only by the readout circuitry. The housing is usually anodized aluminum or zinc-plated steel, rated IP67 for wash down environments. Electrical termination options include M12 connectors, cable glands, or terminal strips, enabling rapid field replacement without reprogramming. Cost-effective for stroke lengths from 50 mm to 1000 mm, the pull rod linear displacement sensor excels in applications where non-contact technology is over-engineered and budget constraints exist.

Widely deployed in packaging machinery, conveyor sorting systems, textile looms, woodworking equipment, and agricultural sprayers. Also found in valve feedback, damper controls, automotive test benches, and injection-molding clamp units where external mounting and cost efficiency are prioritized over extreme environmental resistance.

Features direct mechanical coupling, simple wiring, and passive resistive or inductive elements requiring no internal electronics. Offers infinite resolution, short response time, and compact external footprint. Tolerates mild misalignment via pivot mounts. Cost-effective for moderate-stroke applications, with easy field servicing and visual stroke indication.
