OPE1275H-128

Incremental Hollow Shaft Encoder OPE1275H Single Channel (Tachometer) OPE2275H Dual Channel Features: O.D. = 28mm 1.10 Motor Shaft Diameter 2 mm 0.079 Motor Shaft length 3.8 mm 0.150 minimum Pulses per revolution 256 maximum Analog Output 100 - 5,000 RPM 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 100 to 25 kHz providing a maximum of 256 cycles per revolution (CPR) This product is designed for general encoding for low-speed applications.
