I searched a month ago for the part number but came up empty. I can tell you it appears to be a 24v NPN type proximity sensor with a 2mm sensing range. 3-wire connector with Gnd, sig and 24v and the signal wire is pulled low (~0.6v) when the sensor is triggered. ![20200517_184145](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/8/89334aada3ee560941495b73bd8ddff4299a50fc.jpeg)
