Model: 400,600,360P/R incremental rotary encoder, AB two-phase. Through the generation of 90 phase between phase A and phase B, the positive and negative directions can be identified to complete the counting pulse signal. Performance: 400,360,600 pulses per revolution. Working voltage: DC5-24V, maximum mechanical speed 5000rpm, electrical response frequency 20K/ s, comprehensive speed 2000rpm. Size: encoder body size: 38 mm; 6x 13mm; Off- platform: 5mm high, 20 mm; The fixing holes are M3 screws, three mounting holes are on the circle of 30, and the other three mounting holes are on the circle of 28; Side outlet. Connection mode: green =A phase, white =B phase, red =Vcc positive power supply, black =V0 ground, please connect the wires according to the above method. Another metal shielding mesh layer is anti-interference. Output: AB two-phase output rectangular orthogonal pulse, and the circuit output is NPN open collector output type. This output type can be directly connected with single-chip microcomputer or PLC with internal pull-up resistance, such as 51 single-chip microcomputer or PLC (the input mode of PLC should be that the switch is connected to 0V to work). Note: If the encoder is not connected to the equipment, it is impossible to directly display the wave on the oscilloscope (open collector output has no voltage output when there is no pull-up resistance). If you want to display the wave, please add two pull-up resistors to AB two-phase output; Usage: used to measure the rotation speed, angle, acceleration and length of objects. Note: Phase A and Phase B output lines must not be directly connected to VCC, otherwise, the output diode burn out. (Due to different printing batches, if there are slight differences in the actual words, it not affect the use) Color: Black Material: Metal Package Contents: 1 * incremental rotary encoder Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
