Incremental Photoelectric Rotary Encoder - 400P/R

This is an outstanding industrial incremental photoelectric rotary encoder crafted from aluminum, featuring a sturdy metal shell and a stainless - steel shaft. It cleverly generates AB two - phase orthogonal pulse signals through the rotation of the grating disk and optocoupler. Each phase produces 400 pulses per round, and with dual - phase 4 - times output, it reaches 1600 pulses per round. Capable of supporting a maximum speed of 5000 r/min, it's perfect for measuring speed, angle, angular velocity, and other data. The encoder has an NPN open - collector output, which can directly work with microcontrollers having internal pull - up resistors. It uses the 750L05 voltage regulator chip, offering a wide DC 4.8V - 24V power input range and is compatible with Arduino, STM32, PLC, and other microcontrollers. Note that the NPN open - collector output requires pull - up resistors for oscilloscope display. Specifications include a supply voltage of 4.8V - 24V, an encoder body size of φ39x 36.5mm, an output shaft diameter of φ6 x 13mm, an outside shaft platform of φ20 x 4.85 mm, M3 fixing hole screws, and a weight of 234 g. The shipping list contains an encoder, an encoder mounting bracket, a 6mm coupling, screw accessories, and two 10K resistors.

Using this industrial incremental photoelectric rotary encoder is easy. First, install it properly with the included mounting bracket and screw accessories. Connect it to your microcontroller, like Arduino or STM32, using the 6mm coupling. Remember, since it has an NPN open - collector output, if you want to use an oscilloscope to display the signals, you'll need to add the provided 10K pull - up resistors. The encoder can handle a wide power input range from 4.8V to 24V, so you can choose a suitable power source. When it comes to maintenance, keep it clean and avoid exposing it to extreme temperatures or moisture. Check the shaft and connections regularly for any signs of wear or damage. With proper use and care, this encoder will serve you well for speed, angle, and angular velocity measurements.
