Speed Measuring Sensor

1. Using imported groove optical coupling sensor, width 5mm.
2. It has the output state light, if output high level, the lights are off. if output low level, it on.
3. If it covered, it will output high level; otherwise, its output low level.
4. Good signal and waveform, with a strong driving ability for more than 15mA.
5. Equipped with a fixed bolt hole, easy install.
6. Use the LM393 wide voltage comparer.

1. On-board MAX485 chip, A low power consumption for the RS-485 communication, slew-rate limited transceiver.
2. A low power consumption for the RS-485 communication
3. Onboard then 5.08 (mm) pitch 2P terminal to facilitate RS-485 communication wiring.
4. Slew-rate limited transceiver
5. All pins of the chip have been lead to can be controlled through the microcontroller.
6. Convenient RS-485 communication wiring
7. Multiple Units can be connected to the same RS-485 bus wiring.
8. All Chip pins are brought out for proper controls
