Overview

The PT8420 series 4-20mA string pot to 60 inches is ideal for monitoring the stroke of a hydraulic cylinder and other applications requiring position data acquisition in harsh environments.

As a member of our family of NEMA 4-rated cable- extension transducers, the PT8420 series 4-20mA string pot provides a feedback signal that is proportional to the linear movement of a traveling stainless-steel extension cable. Simply mount the body of the transducer to a fixed surface and attach the extension cable to the moving object.

Benefits

Absolute Linear Position to 60 inches (1524 mm)
Aluminum or Stainless Steel Enclosure Options
VLS Option to Prevent Free-Release Damage
IP68 / NEMA 6
Hazardous Area Certification
