KJT ring proximity switch has a variety of sensing apertures of 6mm / 10mm / 15mm / 21mm, with dynamic and static working principles. High resolution: even a small steel ball with a diameter of 0.6mm can be reliably detected, with a particularly fast response time of 0.2ms. The pulse extension and sensitivity can be set through the potentiometer. With wires and connectors, normally open and normally closed functions are optional.
The ring sensor is suitable for the detection of metal parts on automatic conveying system, such as spring screws and so on. The sensor has the characteristics of high resolution and short response time.
The proximity switch produced by Nanjing KJT Electric Co., Ltd. can completely replace imported proximity switch brands such as Turck, Omron and P+F.
