Description:IR switch stands for Infrared. Infrared switches can be used to operate a device in a non-contacting wire free fashion.The module has an IR transmitter and receiver pair that face each other across a U-shaped housing. An object moving through these uprights breaks the IR beam.IR switch use as an optical limit switch or to detect when something is open or closed if it causes an object to move in or out of the beam.The sensor output is normally LOW and the red LED on the module will be lit. If the IR beam between the uprights is broken, the output goes HIGH and the LED goes off.The Infrared Counting Sensor Module is used to count or detect objects that move through the U-shaped detector uprights.Application:Industry countingMotor speed testing.Features:Working voltage: DC5VWorking current: 20MA4Output current: 16MA (can directly drive the relay)Emission angle: straight line (infrared light)Receiving angle: <10 degreesResponse time: 2msWorking temperature: -25 ~ 60 degreesWorking environment: indoor (not waterproof)
