Question:
Explain the LED input signal and output sampling time for the analog output model of the light convergent reflective type Optical Sensor B5W-LB.
Answer:
Refer to the Explanation below for the recommended LED input signal and the recommended sampling time of this Optical Sensor.
Explanation:
Relatively large current flows through the LED of the B5W-LB series to detect an object with low reflectivity. In order to reduce the load on the LED (for longer life), it must be designed to be pulse-driven rather than DC-driven. The internal circuit and external connection diagrams are shown below.
The following figure shows the recommended pulse signal input to the sensor input terminal: 1 and the sampling time of the sensor output. For details, see B5W-LB: User’s Manual.
Quick tips
By designing to be pulse-driven, the effect of external light can be canceled by the external circuit. For details, see B5W-LB: User’s Manual.
