Description:
The OPE1275H and OPE2275H are designed for small shafted motors with a shaft diameter of 2 mm [0.079”] and
a minimum length of 3.8 mm [0.150”]. The OPE1275H provides a single channel analog output for speed of
rotation while the OPE2275H provides a dual channel analog output for speed and direction of rotation.
The output of the OPE1275H provides a rise and fall pulse providing the designer two slopes for each pulse
doubling the count capability. The OPE2275H provides quadrature rise and fall pulse patterns providing the
design engineer 4 times the pulse per revolution count.
The OPE1275H and OPE2275H are very easy to assemble on your motor shaft using a #1 Phillips screwdriver.
Power requirements are 5 volts ± .5 volts.
Electrical connection is achieved with a 4-pin Molex 53048-0410 connector providing V+, Ground and Output pins.
The mating connector is a 4-pin Molex 51021-0400 (Terminal pin 50058 or 50079)
or equivalent.
Mounting of the hollow shaft version of the OPE1275 and OPE2275 is achieved with a stick-on transfer adhesive
pre-applied to the back of the housing. Just peel off the protective base and press the encoder to your motor.
Frequency response is from DC to 25 kHz providing a maximum of 256 cycles per revolution (CPR)
This product is designed for general encoding for low-speed applications.
Applications:
Printer motors
Machine automation
