Reed switch sensor, in cooperation with programmable logic controller (PLC) and microcontroller with a wide working voltage range, has a high running speed. When weak magnets are used, the dry spring sensor can also detect any ferrous metal parts.

Reed switch (also known as reed switch, magnetically controlled switch, etc.) is an electronic component that uses magnetic field to control its switch. When choosing and distinguishing the quality of reed switch, you can refer to the following aspects:

Dry reed relay is composed of reed switch (dry reed switch tube) and durable magnet or stirring coil. It consists of two magnetic and conductive reeds sealed in parallel in a glass tube filled with lazy gas to form a switch element.

The plastic-sealed reed switch consists of a pair of tongue springs made of magnetic materials, which are sealed in a glass tube filled with inert gas. The end faces of the tongue springs overlap with each other but leave a small gap.

Matters needing attention in using reed switch

Danish electronic reed switch, relay and sensor products are especially suitable for green applications that need environmental protection, sustainable development and reduced energy consumption.

Reed switch is also called magnetic reed switch, magnetic switch, etc. Lets explain the manufacturing steps of reed switch.

In 1936, Walter B. Ellwood of Bell Telephone Laboratory invented the magnetic reed switch, and applied for a patent in the United States on June 27th, 1940, with the patent number of 2264746.

The small float level switch is a liquid level control part with simple structure and convenient use. It is equipped with complex circuits and will not be disturbed. As long as the material is selected correctly, any liquid, pressure and temperature can be used.

Like other products, reed switch can be divided into domestic products and imported products. At present, reed switch used in our liquid level switch industry is imported, while most of the domestic products are used in toys.

Let me introduce some technical knowledge about reed switch

1. When using reed switches, they are rarely used directly. Generally, cutting and bending are carried out. Matters needing attention in these processes are as follows: (1) The size of cutting or bending shall be calculated from the center of contact or the end of magnetic spring. If calculated f
