Celesco PT1MA-30-UP-420E-MC4 Transducer Cable

PT1MA-30-UP-420E-MC4 is TE Connectivity’s PT1 series cable-actuated industrial string potentiometer, delivering a 30-inch (762 mm) travel and a 4–20 mA output for direct process-control feedback. As a cable-extension displacement sensor (no encoder), it uses an aluminum plus polycarbonate enclosure that is IP65 rated for dust and water resistance in rugged environments. The full stroke is 762 mm (30 in), and the device offers an accuracy of ±0.15% of end value with a repeatability of 0.05% of end value, ensuring repeatable position feedback across cycles. The MC4 designation refers to the cable-connected interface used to integrate with control systems. This model is well suited for long-travel position sensing in automation, such as monitoring actuator rods, linear slides, or other equipment where a current-loop signal provides robust feedback to PLCs, PID controllers, DCS, data acquisition systems, or other industrial controllers. The rugged housing and the straightforward operation of a string potentiometer make it a reliable choice for systems requiring direct 4-20 mA scaling without external analog-to-digital conversion.
