Relays are electromechanical devices that are used to switch electrical circuits. They are typically used to control higher voltage or current loads with lower voltage signals. The 27E123 relay socket is a non-polarized, 8-pin socket designed for use with a miniature PC board relay. It is able to be easily mounted via self-tapping screws or mechanical fasteners.

The 27E123 relay socket provides superior electrical insulation by utilizing a unique insulation design which utilizes low-coefficient, flame-retardant insulation material. This insulation material is UL rated, allowing for long term robust circuit operation, even in hostile environments. Additionally, the relay socket provides very effective and reliable EMI/EFI shielding that eliminates unwanted radiated/induced noise and interference.

The 27E123 relay socket is composed of three parts: a mechanical housing, an electrical contact block, and a pin contact piece. The mechanical housing is made of a high quality, flame retardant plastic material and consists of a base, a front cover, and a self-locking housing. The mechanical housing mounts directly onto the chassis and provides connection terminals for attaching wires or printed circuit boards. The electrical contact block is composed of the actual contact pieces with a gold-plated contact layer. This contact layer allows for low contact resistance and reliable connection when the relay socket is engaged. Lastly, the pin contact piece is a built-in beam spring type contact which ensures reliable contact between the electrical contact block and the relay.

The 27E123 relay socket is used primarily in the telecommunications and industrial automation industries. It is designed to handle signals with voltage ratings up to 28V DC and current ratings up to 2A DC. The relay socket is also UL rated, providing reliable, secure and vibration-proof performance. Additionally, the socket is suitable for wide operating temperatures ranging from -40°C to 125°C.

The working principle of the 27E123 relay socket is based on the following: the power is supplied to the coil of the relay, which then creates a magnetic flux that is able to move the contact arm of the relay. Once the arm moves, it acts as a switch that triggers the contacts of the relay to open or close. Depending on the type of relay, the contacts may be either normally open (NO) or normally closed (NC). When the relay is activated, a contact arm completes or breaks the circuit and a change in electrical state occurs at the contacts.

The 27E123 relay socket is an essential component in the design and implementation of specialized relay based control systems. Its superior insulation properties and vibration-resistant connections make it the preferred choice for reliable, secure electrical control. Additionally, its compatibility with a wide range of relays makes it ideal for rapidly evolving industrial applications such as industrial automation, transportation, communication systems, medical equipment, and even consumer electronics.
