Sensor is a kind of device used to sense the outside world. There are many types of sensors in the market. What are the structural features of the thread break sensor of our sewing machine today? Now let ingor electronic technology give you a brief introduction.

　　1. Persistence

　　Close to the service life of the switch can reach more than one million times. The reason for such a long life is that the switch is elastic from the vertical direction of the elastic membrane. Although the elastic membrane peristalsis millions of times, but the creep speed is very small, only 0.1 ~ 0.3 mm (including the travel switch), coupled with reasonable material selection, far less than the yield limit of the membrane, so the membrane material can withstand more than one million times of life and maintain its shape. On the other hand, the contact of the switch is vertical contact, with little wear. Contact with screen printing can form enough thickness, and contact a layer of conductive carbon on the silver paste, so as to achieve high wear resistance and self lubrication, so that the service life of proximity switch is ten times longer than that of mechanical contact switch.

　　2. Good sealing performance

　　Because the proximity switch sensor is an integral sealed structure, the contact of the switch is not eroded by harmful gas, and is not easy to be oxidized. It has the characteristics of waterproof and dustproof, and is suitable for various environments.

　　3. Small volume, light weight and reliable structure

　　The design of proximity sensor switches can be arranged and combined into a film keyboard with set density. It is a multi-layer film composite seal structure. All switches between connecting wires and wires are screen printed at one time with a total thickness of 1-3mm. Therefore, the size is reduced, the quality is reduced, and the reliability is improved.

　　4. Rich colors and beautiful appearance

　　The proximity switch can be designed according to the user's design concept, reflecting the color personality in the design, and reflecting the characteristics of material beauty, decoration beauty and comprehensiveness in the decoration effect.

　　5. Reduce the matching cost of mechanical and electrical products

　　The traditional mechanical switch needs to be welded in the installation process, and even use a fixed bracket. Using proximity switch sensor mounting paste, as long as the adhesive tape is removed, it can be firmly adhered to the surface of the machine, so that the circuit can be connected immediately at the outlet of the whole rear circuit socket. Save labor, save materials, reduce support costs.
