  As a   Magnetic Switch China Supplier , share with you. An electromagnetic switch is a switch controlled by an electromagnet, which is a combination of an electromagnet and a switch. When the electromagnet coil is energized, electromagnetic attraction is generated, and the movable iron core pushes or pulls the switch contact to close, thereby connecting the controlled circuit. Electromagnetic switches have a wide range of applications in various industries, and the most common is the contactor in the industrial field. The electromagnetic switch is the control switch on the starter. It is one of the three major components of the starter (DC motor, transmission meshing mechanism, electromagnetic switch). Its working principle is to generate electromagnetic attraction after the coil is energized, which causes the movable iron core to move, thereby pulling on the one hand The transmission meshing mechanism makes the starter pinion move forward and meshes with the engine flywheel ring gea

  As a   Latch Type Hall Sensor Factory , share with you. Before the development of solid-state Hall sensors, magnetically actuated reed switches have been widely used for decades, providing a tried-and-tested and inexpensive solution for position sensing. With the development of Hall-effect technology, Hall-effect sensors have begun to replace reed switches in some battery-powered applications, such as mobile phones, notebooks, consumer electronics and white goods. Latch Type Hall Sensor For design engineers who use Hall switch alternatives to reduce switch size, improve switch quality and durability, and maximize battery life, the new Hall switch technology can provide them with uA switching power consumption while also having The characteristics of high sensitivity, and the cost performance is better than the reed switch. ReedSwitch, also called reed switch or reed switch, is a magnetically sensitive special switch. It was invented by Walter B. Ellwood of Bell Telephone Laboratories

  As a   China Gear Sensor Supplier , share with you. Gear Sensor  is a new type of sensor made using the principle of Hall effect. It adopts a round tube waterproof design. It senses the number of teeth of a ferrous metal gear or rack and converts it into a voltage pulse signal to measure the speed, rotation speed and other parameters of the object. It is widely used in a new generation of automotive intelligent engines, as a speed sensor for ignition timing, and used in abs (automobiles). Anti-lock braking system) as a vehicle speed sensor, etc. Gear Sensor Principle Hall gear speed sensors are widely used in the new generation of automotive smart engines, as a speed sensor for ignition timing, and used in ABS (automobile anti-lock braking system) as a vehicle speed sensor. In abs, the speed sensor is a very important component. In the braking process, the controller continuously receives and processes the pulse signals from the vehicle speed gear sensor and the wheel speed correspon

  As a   Micropower Hall Effect Sensor Manufacturer , share with you. The Hall current sensor is made according to the principle of Hall effect, applying ampere's law, that is, a magnetic field proportional to the current is generated around a current-carrying conductor, and the Hall device is used to measure this magnetic field. Therefore, non-contact measurement of current is possible. Main characteristic parameters of Hall current sensor: Hall Effect Sensor 1. Standard rated value IPN and rated output current ISN IPN refers to the standard rated value that the current sensor can test, which is expressed by the effective value (A.r.m.s). The size of the IPN is related to the model of the sensor product. ISN refers to the rated output current of the current sensor, generally 10~400mA, of course, it may be different according to some models. 2. Offset current ISO The offset current is also called residual current or residual current, which is mainly caused by the unstable working s

  As a   Bipolar Hall IC   China Factory, share with you. Before using the sensor and Hall sensor, be sure to verify the working power supply voltage level and whether the measurement range is consistent with the measured signal! Avoid misuse and mixing of different voltages. In order to facilitate the reference, the following discusses the correct use of the sensor from several aspects. 1. Use environment Sensor and Hall sensor should be free from conductive dust, metal corrosive and insulating gas. Otherwise, a secondary circuit will occur due to conductive dust and objects, or a short circuit between the secondary side power supply and the signal will burn out the sensor. 1.1 Ambient temperature The sensor's specifications will stipulate the normal working ambient temperature range of the sensor, such as -40 to 85 degrees, depending on the product model. It is recommended not to exceed the temperature range specified in the specification, or exceed the normal operating temperatu
