HS0098 Rotary Encoder 400P/R 6mm Incremental Optical Shaft Working Measurement 5-24V ED

The color of wires may vary slightly,so there are two kind of the connection method you should refer to.
one is white=VCC, black=GND, red=A phase, green=B phase, the other is Yellow = A phase, Blue = B phase, Red =Vcc power +, Black = power -
Output is NPN open collector
For measuring goods angle, acceleration, length measurements and the rotational speed
Connecting either the A or B phase to V+ will burn out the transistors.
Small size, light weight, easy to install, cost-effective
Color: Black
Size:5 x 3.7 cm
Package included: 1 x Incremental Rotary Encoder
Note:Light shooting 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 +/- 1-3 cm.
