BL-JGHG-2.7X14-3 Reed Switch 3Pin

BL-JGHG-2.7X14-3

Reed switch acts like a flux conductor. Before operation, the two reeds are not in contact; when the magnetic field is generated by a permanent magnet or an electromagnetic coil, the external magnetic field causes different polarities near the end points of the two reeds. When the magnetic force exceeds the elastic force of the reed itself, the two reeds will attract and conduct the circuit; when the magnetic field weakens or disappears, the reed will be released due to its own elasticity, and the contact surfaces will separate to open the circuit.

The working principle of the reed switch is very simple. Two magnetizable reeds (usually composed of two metals, iron and nickel) that overlap at the endpoints are sealed in a glass tube. The two reeds overlap and are spaced apart. There is a small gap (only about a few microns), and the contacts on the two reeds are plated with a layer of very hard metal, usually rhodium and ruthenium. This layer of hard metal greatly increases the number of switching times and product life. The glass tube is filled with high-purity inert gas (such as nitrogen). In order to improve its high-voltage performance, some reed switches will make the inside a vacuum state.

BL-JGHG-2.7X14-3 reed switch is a 3Pin reed switch with a maximum switching voltage of 100V. According to the switch state, it is divided into normally open reed switch and normally closed reed switch.
