Universal Vibration Sensor for Motorcycles and Cars, Alarm and Anti-theft Device, Motorcycle Alarm Universal Vibration Sensor for Motorcycles and Cars, Alarm and Anti-theft Device, Motorcycle Alarm Parameters: Material: ABS + Electronic Components Output Current: ≤100mA (Maximum Load Current) Sensitivity: -105dB Silent Current: ≤6mA Rated Operating Voltage: 12V Minimum Operating Voltage: >5V Trigger Pole Number: Single-pole trigger output Interface Type: XH2.54 or 2510 three-wire interface (interface socket), 2.543P is the common model. If you need the 25103P interface, please contact us. Trigger Method: Negative trigger grounding or positive 12V trigger Operating Voltage: DC 10V-16V Sensitivity: Rotatable adjustment Indication Method: LED red light indicator Notes: 1. The blue wire is the signal output of the 358 operational amplifier. If the signal has no amplitude, it is high (the IO port should be pulled up); if the signal has amplitude, it is low (the signal is grounded). 2. Red wire: +12V power supply. 3. Black wire: Ground. **Caution!** If the output is connected to a high level, a 100-ohm or smaller resistor must be connected in parallel. This resistor cannot be replaced if powering the wireless transmitter module. Connect the two black wires to the positive and negative power input terminals of the module, respectively. (DC alarm horn) It is best to use an external relay control to avoid high current damage to the internal components of the sensor (for reference only). **List:** 1 x 1-meter/39.37-inch black sheathed cable + anti-theft device 1 x instruction manual View more product information 1.
