## Description

#### Introduction

This 4-wire slot type photoelectric switch integrates an optical transceiver module, providing stable performance and strong anti-interference ability. Power it at 10-30V. The detection range of the module is the slot width, which is 5mm. There is an indicator onboard for feeding back device status in real-time. The 4-wire interfaces of the module can be freely switched between normally open and closed status. Also, it comes with protection mechanisms like short-circuit protection, overload protection, and reverse connection. This product is well suitable for distinguishing transparent objects, detecting high-speeding moving things, or counting materials, etc.
