This Incremental Photoelectric Rotary Encoder - 400P/R is an industrial incremental photoelectric rotary encoder with aluminum material, metal shell and stainless-steel shaft. It generates AB two-phase orthogonal pulse signal though the rotation of the grating disk and optocoupler. 400 pulses/round for each phase, and 1600 pulses/round for dual-phase 4 times output. This rotary encoder supports max 5000 r/min speed. And it can be used for speed, angle, angular velocity and other data measurement.

The photoelectric rotary encoder has a NPN open collector output. It could work with Microcontroller with internal pull-up resistors directly. And it is using 750L05 voltage regulator chip, which has a DC4.8V-24V wide range power input, compatible with Arduino, STM32, PLC and other types of microcontrollers.

Works well

Haven't had any problems so far. Had only two of these, bought 3 more. Probably will expand in the future too.

Mauvaise expérience avec se produit.

Le diagramme de branchement inscrit sur RobotShop est erroné, ainsi que ceux trouvé sur le web. Les infos sur l'encodeur sont tous en caractère Chinois. Selon RobotShop: White = VCC | Black = GND | Red = Phase A | Green = Phase B. Mais en réalité: Red = Vcc | Black = GND | White = Phase A | Green = Phase B Depuis le premier branchement, l'encodeur donne de mauvais signal (branché en VCC à 9 volt dc). Est-ce dû qu'il y a eu 9 volt sur la phase A? (Commentaire: RobotShop a corrigé cela en fonction de vos commentaires.)

Good product

This worked right away. The only thing I would have liked is a differential output, i.e. A+ A- B+ B-. But this didnt cause a problem for me at the moment.
