Looking for Reed Relays?

The below manufacturers are all of our authorised partners that produce Reed Relays or related products.

Reed Relays

The reed relays comprise of reed switches and a magnetic coil within a sealed envelope and are in the circuit; this electronic switching mechanism is controlled by an electromagnet applying the magnetic field. Here at Rhopoint Components, we offer a wide range of reed relays from industry-leading manufacturers in a variety of package sizes (including non-standard), pinouts, switching currents, multi-pole configurations and other selectable properties to cater for most applications. Focused on quality and reliability, the reed relays available from us are a popular choice for many safety-critical applications, including automated test equipment and instrumentation, medical or security equipment, while the range of high voltage relays of up to 15kV is often used for high voltage power supplies.
