Reed Relays

Reed relays are one of the oldest and most basic forms of electronic switch, which are used to electrically control an appliance or system. A reed relay is simply a switch that uses a magnetically operated, or sometimes optically operated, reed to act as its switch. When the relay is energized, the magnetic field generated by the reed causes the reed to move and make or break a contact. This contact then allows the relay to open or close a circuit, depending on the desired logic.

SLR412SD Application Field and Working Principle

The SLR412SD is a high current reed relay capable of continuously handling current loads up to 3 Amps at 24 Volts DC (36V DC Peak). It is a compact size, open frame type of relay and it is ideally suited for use in panels, junction boxes and wiring harnesses. It is also suitable for use in automotive and other applications requiring low load switching and power reliability.

The SLR412SD is a single form A (SPST) type of reed relay. The actuating element used in this relay is a reed which is made up of a pair of small ferromagnetic strips. When the input voltage is supplied to the reed, it moves due to the magnetic force generated by the applied magnetic field. When the reed moves, it pushes the contact and makes or breaks the switch. The switch is reset by the reed’s return spring, once the input voltage is removed.

The SLR412SD is also designed with an external magnetic shield. This magnetic shield helps to protect the magnetic field coming from the reed during switching operation. This helps to prevent undesired response due to external magnetic fields.

In addition, the SLR412SD is also designed with a special feature that allows it to operate in conditions with high shock and vibration. It uses mechanical dampers that reduce contact bouncing and chatter, providing a reliable switching performance even under extreme conditions.

The SLR412SD reed relay is versatile and can be used in a variety of applications such as sensing, current conduction, data transmission, and switching. It can be used to switch a large number of loads, from home appliances to industrial and automotive applications.

These relays are very reliable and can withstand high switching currents and loads. They are also designed to have a low contact resistance, which helps to reduce the power consumption of the device. The relays are also designed to be long-lasting and have a wide operating temperature range. This makes them ideal for use in industrial and high-temperature applications.

The SLR412SD reed relay is an ideal choice for applications requiring a reliable and durable low-current switch. It is also very cost-effective and has a wide range of applications. With its highly reliable performance and efficient operation, the SLR412SD is one of the best reed relays available in the market.
