8002-12-00

Reed relays are composed of a coil and a magnetic armature or "reeds". The coil creates a magnetic field when power is applied, which moves the armature to close an electrical contact. Once the power is removed, the armature will move away from the contact and open the circuit.Reed relays are used for a variety of applications, such as remote control systems, process control, automation, and motor control. They are often used in applications where contact quality is critical, and when low current/voltage switches are required. Reed relays are ideal for applications where space is a concern and require reliable operation.

8002-12-00 Application Field and Working Principle

8002-12-00 is an ultra-miniature reed relay with a 0.75 mm height and is capable of switching up to 3A. This relay is designed for use in a variety of applications, such as motor control, load switching, alarms, instrumentation, and process control. The 8002-12-00 is an ideal choice for applications where space is a concern and high reliability is required.

The 8002-12-00 comes with an 8-pin configuration with a dual circuit contact design. Each contact includes a reed switch and an associated connector. The reed switch contains a hermetically-sealed magnetically operated armature that is actuated by an electrically energized coil. When the coil is not energized, the armature remains stationary in a binary state separating both contacts and providing an open circuit. When the coil is energized, the magnetic field pulls the armature, connecting both contacts and resulting in a closed circuit.

The 8002-12-00 reed relay can be requested with a range of contact configurations such as SPST-NO (single pole, single throw normally open), SPDT (single pole double throw), and DPST-NO (double pole single throw). The contact rating is 3A (30 Vdc, 10 W). The coil resistance range is a minimum of 330 ohms and a maximum of 3500 ohms. The general purpose operating parameters are 5 Vdc, 12 Vdc, 24 Vdc, 48 Vdc, and 6 Vac. Special purpose parameters can be requested.

The 8002-12-00 reed relay is manufactured with an epoxy sealed coil enclosure, allowing its use in various harsh environments. The coil is encapsulated to protect against shock and vibration, and the entire unit is shielded to avoid EMI/RFI interference. This relay features fast response time of 10 milli-seconds and a long life of up to 30 million operations.

The 8002-12-00 is the ideal choice for applications where space and reliability are critical. With its small size, high current capacity, fast response time, and long lifetime, this reed relay is a great solution for applications such as motor control, instrumentation, and process control.
