our engineer team has newly developed the P series encoders, from the original P48 to the later PN35,PC48, PN58, PC58, PN72. More and more models are available to meet the needs of customers. First, let's briefly introduce the P series. The P series is also an incremental type encoder, but in terms of thickness, compared to the original K series, the P series is lighter and thinner, and can be applied to robots, servo motors, etc. After the customer purchases our P series, installation may become the first challenge the customer faces. So how do customers install it after receiving the goods? Here we will explain in detail.

PN58 has a mechanical soft connection structure, which is unique designed with photoelectric induction and ultra-thin overall. 

With an LED to indicate the zero position of the encoder. Its also easy to install and debug, various of shaft holes available, dust-proof protection, and can solve problems for encoders in high run-out motor shaft and installation in limited spaces.

 With outer diameter 58mm, thickness 14mm and hollow shaft up to 24mm. All P series will be equipped with a wrench, which is convenient for customers to install.

If you ordered the PN58 with UVW signal. 

First you need to confirm the starting zero position of the motor and lock it tightly before installing the encoder to ensure that motor shaft is not moving until the encoder is finished installation, otherwise the encoder and the motors zero position cannot be aligned. 

Then put the encoder (2) directly on the motor shaft and gently push it to the motor platform by hand. Screwed the two M3*6 bolts (3) at the same time, but do not tighten, just enough to rotate the encoder by hand. 

The second step is to fix the spanner (A) on the slot of the encoder shaft sleeve (outer ring) and then use the spanner (B) to tighten the lock nut (recommended tightening force is 13-16nm). 

Finally powering on after checking all are correct, please confirm again that the motor is in the zero locked state, and then turn the encoder (2) left and right by hand, observe the LED on the encoder, when it is on, the zero signal is aligned, then tighten the two M3*6 bolts (3) and keep the LED on.


If you chose the PN58 without UVW signal, 

the first step is to put the encoder (2) directly on the motor shaft (1) and gently push it to the motor platform, then tighten the two M3*6 bolts(3) at the same time. 

The second type is to fix the spanner (A) on the slot of the encoder shaft sleeve (outer ring) and then use the spanner (B) to tighten the lock nut (recommended tightening force is 13-16nm).


At last, thank you for buying Hengxiang encoder, here I will have a short introduction of our company. Hengxiang encoder factory, located on Shanghai, set up in 2001, is a professional manufacturing high-tech corporation, provides research and manufacturing, entity integrating opticalmechanical and electronic design. After development for many years, rotary encoders now have 10 series and over 100 sorts, both popularly sale around the world. Our rotary encoders are widely used for automation field, such as, Office equipmentWater conservancy equipmentElectrical equipment and so on.
