UNIMEASURE JX-PA SERIES RATIOMETRIC VOLTAGE OUTPUT

The UniMeasure JX-PA Series linear position transducer with analog output is primarily 
for  use in moderate duty applications in wet or dry environments. The chemical resistant 
thermoplastic case of the transducer provides optional IP-65 (NEMA 4X) ingress protection 
for applications where exposure to wash down, rain, oil and other liquids may occur. The 
sealed case is achieved through the use of o-rings and a low friction shaft seal. An integral 
dust wiper insures that the wire rope stays clear of debris as it is extracted and retracted.  
Electrical connection options include body mounted sealed plastic connector with mating 
connector  or a sealed bulkhead fitting and three conductor electrical cable of user specified 
length. If connector with mating connector option is chosen, the mating connector is available 
with or without electrical cable attached. As an installation  convenience, optional connector locations on the transducer 
body are offered. In addition, the wire rope exit direction may be specified at time of order or may be user adjusted at 
time of installation. Typical applications include but are not limited to forklift positioning, suspension travel measurement, 
valve positioning, liquid level measurement, flood and irrigation gate monitoring, and saw blade positioning.
