The PK Series Encoder is available in several configurations as defined by its complete model number:
PK2W - XX - YYV
W = Series:
3 = Bodine style (1.812" mounting centers, #40-40 screw)
4 = Bison style (1.500" mounting centers, #6-32 screw)*
YY = Input voltage (volts DC): 5, 12, 15, 24
(Other voltages may by available. Consult Factory)
XX = Pulses Per Revolution (PPR): 2, 4, 8, 10, 30, 32, 60, 64
(Other choices may be available. Consult factory)
The PK23 and PK24 Series encoders are the newest additions to
the Minarik encoder family. These encoders output a channel
square wave to provide more accurate speed indication and reg-
ulation when used with digital accessories. Their hollow shaft
design allows for easy installation without tedious alignment pro-
cedures. The accuracy and ease of installation make the PK23
and PK24 Series the ideal choice for your encoder feedback.
