LINEAR AND ROTARY POSITION
WPM Series
Rotary position transducer, servo mount
Available in servo mount styles, the WPM Series rotary transducer provides
long life by utilizing the proprietary MystR
®
conductive plastic film, precious
metal wipers and shielded ball bearings on the stainless steel shaft.
The MystR
®
film provides exceptionally long rotational and dither life without
sacrificing microlinearity or resolution. The shielded ball bearings ensure long
life even with side load conditions.

Supply voltage (max.): 60 Vdc
Total resistance: 5000 Ohm
Backlash (max.): 0.01 %
Shaft Ø: WPM5KA4* 3,175 mm (0.125 in)
WPM5KB1* 6,35 mm (0.25 in)
Termination: Gold plated solder terminals
Bearing type: Ball bearings
Mechanical travel: Continuous rotation
Approvals: MIL-PRF-39023 qulaified
