Draw Wire Sensor 20-3000mm Stroke String Potentiometer 12-24VDC IP67 for Rock Drill Feed Beam

The Winston draw wire sensor is a heavy-duty linear displacement transducer designed for precision position monitoring on rock drill feed beams, hydraulic cylinders, and mining jumbo boom assemblies. Covering an extensive measuring stroke from 20mm up to 3000mm, this high-performance string potentiometer delivers outstanding linearity of ≤±0.5% FS and resolution between 0.1mm and 5mm, ensuring smooth, repeatable measurement in automated rock drilling cycles. Powered by 12-24 VDC onboard cart systems, it features an adjustable output signal and a dedicated M23 6-pin IP67 waterproof connection cable to isolate moisture, dust, and hydraulic oil. The sensor incorporates an ultra-durable, wear-resistant stainless steel pull cable and a rugged aluminum/stainless steel body capable of enduring severe 100g shocks and 10-2000 Hz vibrations across a wide -40°C to +85°C operating range. Offering seamless flange or bracket mounting, it serves as a robust OEM replacement part for underground mining, tunnel excavation, and heavy-duty construction machinery.
