MS05-2A87-78D

Reed relays are a form of electromechanical switch used in many applications in which it is necessary to control electric current with a low-power signal. The MS05-2A87-78D Reed relay is a popular choice due to its low cost, small size, and reliable performance.

Introduction

A Reed relay is an electromagnetic switch composed of two parts: a coil and a number of small reed contact blades or strips. The coil is energized by an electrical current, which will cause the reed strips to be magnetically drawn towards it. This creates an electrical connection between the two parts that can be used to control electric current in a circuit.

Construction and Working Principle

The MS05-2A87-78D Reed relay consists of a glass-encapsulated coil and a magnetically coupled contact assembly. The contact assembly contains three reed strips that are arranged in a hermetically sealed stainless steel container. When the coil is energized, it produces a magnetic field which causes the reed strips to magnetically align with the coil and create an electrical connection.

The MS05-2A87-78D Reed relay has a maximum contact rating of 6A 250V AC/DC. It is capable of switching both AC and DC current and has a switching time of less than 20 milliseconds. The relay is available in several different contact configurations such as SPST normally open, SPST normally closed, and SPDT.

Applications

The MS05-2A87-78D Reed relay is typically used in applications such as solid-state circuit breaker panels, automotive relays, and telecom switching systems. It is also used in low-voltage protection systems to ensure safe electrical connection during emergency situations. Other applications include home and commercial security systems, fire alarm systems, industrial control panels, and various forms of motion control.

In addition, the MS05-2A87-78D Reed relay is often used in conjunction with electronic timer circuits, logic devices, and other types of circuitry. It can be used to switch a variety of different signals, including digital ones, as well as provide a secure connection when powering electric components. The small size of the MS05-2A87-78D Reed relay makes it easy to fit into tight spaces and can help to reduce the overall cost of an electrical system by saving on labor costs.

Conclusion

The MS05-2A87-78D Reed relay is an inexpensive and reliable electromechanical switch used in a variety of applications due to its low cost, small size, and reliable performance. The relay is available in various contact configurations, can handle both AC and DC current, and has a switching time of less than 20 milliseconds. The MS05-2A87-78D Reed relay is typically used in solid-state circuit breaker panels, automotive relays, telecom switching systems, and low-voltage protection systems for safe electrical connection during emergency situations.
