Transmitting voltage: 12V ;Transmit working current: 500mA; Receive output: 5V DC. | Normal use distance: 8~23mm. | Sensing distance: Receive output 5V500mA at 8mm; Receive output 5V150mA at 15mm. | If the receiving and the rectification and voltage-stabilizing circuit are partially lost, the transmission transmission efficiency is up to 90%; | Note: Please do not use less than 8 mm when using it, otherwise it will be overpressure damaged if it is close!
