Shandong Zhuoxin Machinery Co., Ltd. has various types of GU5 intrinsic safety proximity sensors, including proximity sensors, photoelectric sensors, magnetic sensors, pull rope sensors, and deviation sensors. Proximity sensors, also known as contactless switches, are composed of oscillators and amplifiers. After the oscillator is activated, an alternating magnetic field is generated on the sensing head of the sensor. When the metal body approaches the sensing area, eddy currents are generated inside the metal body, absorbing the oscillator energy and causing it to stop vibrating. After amplification, it is converted into a switch signal. 1、 Main performance 1: Power supply voltage: C12V (external intrinsic safety power supply), working current 15mA. 2. Sensor output signal: Level≥ 5V； Level≤ 0.5V. 3. The action distance is 1-5mm. 4. Action performance: When the metal body moves to the sensor's action range, the sensor outputs the level, and when it returns outside the action range, the sensor outputs the level. 5 intrinsic safety parameters:& &nbp;&nbp;&nbp;&nbp;&nbp; Ui: 12V&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp;&nbp; Ci: 0μ F; The proximity sensor is used in combination with the curved turnout warning device, installed at the turnout of the locomotive running underground in the coal mine. The movement of the switch rail: distance from the sensor≤ 5mm, sensor output closed, distance sensor> 5mm, sensor output disconnected.
