LM12-3005NA Range 5mm Proximity Switch NPN NO Sensor

Proximity switches is the most common solution for non-contact detection. And the inductive type is the widely used proximity switches, which is through the electromagnetic waves to detect the metal abject near the sensor detection surface. In application , this is a very simple technology to detect 1”~2”metal object . YUMO Electric offer different series proximity sensor , that included inductive, photoelectrical, capacitive and etc. YUMO Electric continues to improve the performance and quality , enabling the sensors in a world-class level . If you are searching for proximity switch , YUMO will be your best choice .

Product Description

   Inductive proximity switch is composed of three parts: oscillator, switch circuit and magnified output circuit. The oscillator will generate an alternating electric field. When hemetal object approaches this electric field and reaches the induction distance, whirlpool will generate in metal object, resulting in attenuation of vibrati on and then stop. The changeof vibration and stop of oscillator is treated by begid stage magnified circuit and convertedto switching sign, triggering driving con-contact detection.
