Description:
The OPE1275S and OPE2275S are designed for small shaft motors. The OPE1275S provides a single channel
analog output for speed of rotation while the OPE2275S provides a dual channel analog output for speed and
direction of rotation.
The output of the OPE1275S provides a rise and fall pulse providing the designer two slopes for each pulse
doubling the count capability. The OPE2275S provides quadrature rise and fall pulse patterns providing the
design engineer 4 times the pulse per revolution count.
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.
Frequency response is from DC to 25 kHz providing a maximum of 256 cycles per revolution (CPR) and 1024
quadrature states per revolution (PPR).
This product is designed for general encoding for low-speed applications.
The OPE1275S and OPE2275S are fully assembled and ready to be connected to your application.
Applications:
Printer motors
Machine automation
Machine safety
