1、Various angle sensors, tilt sensor, output with relay, direct connection to high current load, can be applied to various equipment equipment dump protection, appliance dumping protection. 2、The sensor defaults to a highly sensitive SW-520D angle sensor, which can also be used with different angle sensors to achieve different functions, such as a 45 degree angle sensor, a 90 degree angle sensor, or other angle sensors. 3、The comparator output directly drives the relay and can be connected to AC or other equipment. 4、With potentiometer to adjust sensitivity. 5、With 4pcs 3mm fixing bolt holes for easy installation. 6、Output with blue terminal block for easy wiring. Item Type: 12VDC Relay Module Current: Greater than 100mA Module instructions: 1. The initial state of the relay depends on the conduction and disconnection of the tilt sensor. When it is turned on, the relay is closed, the common terminal is connected to the normally open end, and when the tilt sensor is disconnected, the relay is disconnected, the common terminal and the normally closed state. End on; 2. The tilt sensor is generally installed in the normally open state in the initial state, so that the tilt sensor and the relay are not in the working state, and the service life is prolonged; 3. The default SW-520D sensor is used for 90 degree tilt detection of the object. For other angles, please consult the seller. 1 x Relay Module with SW-520 Tilt Sensor
