Impedance 7.9” [200 mm] 5.3” [135 mm] The PT9420 is a great value for demanding long-range applications requiring a 4 - 20 mA linear position feedback signal. Sealed to meet NEMA 4 standards, this Cable-Extension Transducer will perform even under the harshest of environmental conditions. As a member of our innovative family of NEMA-4 rated cable-extension transducers, the PT9420 offers numerous benefits. It installs in minutes, functions properly without perfectly parallel alignment, and when its cable is retracted, it measures only 6”. 100M ohms @ 100 VDC, min.

The VLS option prevents the measuring cable from ever reaching a damaging velocity during an accidental free release. This option is ideal for mobile applications that require frequent cable disconnection and reconnection. It prevents expensive unscheduled downtime due to accidental cable mishandling or attachment failure. How To Configure Model Number for VLS Option: VLS 9420 - R - A B C - D E F G creating VLS model number (example)... 1. select PT9420 model 2. remove “PT” from the model number 3. add “VLS” 4. completed model number !
