Reed relays, such as the 7142-05-1010, function by using an electromagnetic coil to draw a thin metal reed closer to its switch contacts. Once the reed is closed, electricity can flow between the switch contacts. In addition to switch contacts, reed relays also contain a sealed glass envelope, often oval or rectangular, and the coil itself. The sealed envelope is designed to protect the contacts from the environment by sealing them off with an inert gas and blocking out dust and moisture.

Reed relays are most commonly used in environments where low power loads (< 500 mA) need to be controlled precisely. They are especially attractive for applications where long life, low power consumption, and fast switching times are needed; e.g. USB, Ethernet, data transmission, test instrumentation, audio, and video. Highly reliable reed relays with quiet switching performance can also be used where switching with minimal interference is essential.

Reed relays work on the principle of electro-magnetic induction. When current is applied to the coil, it causes the reed contacts to close or open depending on the direction of the current. The force generated by the coil is proportional to the amount of current it receives, and thus the reed contacts can be opened or closed as required. The advantage of using a reed relay is that it can be switched rapidly as the coil does not need to energize for the contacts to move. This also means that the amount of power used to operate the relay is relatively small.

The 7142-05-1010 is a low-profile reed relay perfect for applications where space is a concern. It is extremely reliable due to its gold-plated contacts and hermetically sealed glass envelope. In addition, it has a built-in diode for protection across the coil, as well as multiple mounting options.

The 7142-05-1010 is capable of switching resistive loads up to 500mA with switching speeds as fast as 0.2 ms. The operating temperature range is -55°C to 105°C, making it suitable for a variety of industrial applications. The maximum voltage rating is DC 200V and the insulation resistance is above 10GΩ. This makes the 7142-05-1010 robust and reliable, making it well suited for communication systems, home appliances, automotive electronics, and various other applications.

The 7142-05-1010 is one of the many types of reed relays available on the market, each with its own advantages and disadvantages. Reed relays are highly reliable and very durable, and they offer quick and quiet switching. This makes them ideal for many applications, particularly where space is at a premium. For these reasons, they are increasingly becoming the go-to choice for many electrical engineers.
