As long as the non-transparent object passes through the slot type, it can be triggered (used with our car code wheel) to output TTL low level. The Schmitt trigger is used to shake the pulse, which is very stable and can be used for measuring the speed of the car, measuring the distance and the like! M3 screw mounting holes at both ends.\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e \u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:16px;\"\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e \u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003eWorking voltage: 3.3V-5V\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003eOutput form: digital switch OUT output (0 and 1)\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e \u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:16px;\"\u003e\u003cstrong\u003eInstructions for Use:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e \u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003e1.
