SRF06 4-20mA Current Loop Ultrasonic Ranger FinderRobot Electronics
- Robot Electronics
The SRF06 is a low cost ultrasonic ranger with a 4-20mA current output. The SRF06 is powered from the 4-20mA current loop and requires no other power. Measurement range is from 2cm to 5.1mtrs. Current output is from 4mA at zero range to 20mA at 5.1mtrs (510cm), which gives a nominal current of 4mA + 31.37uA/cm. The SRF06 requires a loop driving voltage of 9v to 24v. The SRF06 automatically performs continuous ranging every 70-100mS.
The SRF06 has only two connections, the positive and negative current loop. An on-board diode protects the module in case of reversed connections.
