Encoder Counter Sensor HS-S58P

1. Introduction

The shaft encoder counting sensor uses a slot type through-beam photoelectric sensor, which is composed of an infrared LED and an NPN photoelectric triode, with a slot width of 5.9MM.As long as the opaque object passes through the slot, it can trigger the output TTL low level.Using a Schmidt trigger to debounce the pulse, it is very stable and can be used for applications such as measuring the speed and distance of small cars, etc.
