Power Relays

What is a Power Relay?

A power relay is a switch which uses an electromagnetic coil in order to close or open a circuit. Power relays also contain an armature, a spring and one or several contacts. If the power relay is designed to normally be open, when power is applied, the electromagnet attracts the armature, which is then pulled in the coil’s direction until it reaches a contact, therefore closing the circuit. If the relay is designed to be normally closed, the electromagnetic coil pulls the armature away from the contact, therefore opening the circuit.

Types of Power Relays

Future Electronics has more than 1,500 power relays available, offering one of the most comprehensive portfolios of general purpose, Miniature and Sub Miniature Power Relays. The largest of all relay categories, we have every contact configuration combination, including many SPST, SPDT, DPST, DPDT as well as 3 pole, 4 pole and even 6 pole power relay solutions. Our parametric filters can refine your automotive relay search results by Contact Arrangement, Contact Current, Coil Voltage and Termination Style. Our inventory includes a huge selection of sealed and non-sealed power relays with Coil Voltages from 2.7 V to 460 V. The most common values for maximum contact current are 5 A, 10 A and 30 A. We also carry power relays with maximum contact current as high as 500 A.

Power Relays from Future Electronics

Future Electronics has a full power relay selection from several manufacturers that can be used when looking for surface mount power relays, PCB relays, relay sockets, or power relays in DPDT, SPST, DPST or SPDT combinations for any circuit that may require a power relay. Simply choose from the power relay technical attributes below and your search results will quickly be narrowed in order to match your specific power relay application needs.

If you have a preferred brand (e.g. Tyco Electronics, formerly Potter and Brumfield; or Panasonic Electric Works, formerly Aromat) you can refine your automotive relay product search results by choosing your preferred automotive relay brand below. We also offer a world-class selection of Power Relays from American Zettler, Hongfa Relays, Magnecraft and Song Chuan.

Applications for Power Relays:

Power relays are used for many different applications, including:

  • Automotive electronics

  • Etc.

Power relays are used for switching a wide variety of currents for applications including everything from lighting control to industrial sensors. At Future Electronics, you will find such a huge selection of Power Relays from 1A to 300A capacity. Simply choose the current that matches your Power Relay requirements from the Amp ratings below.

Choosing the Right Power Relay:

When you are looking for the right power relays, with the FutureElectronics.com parametric search, you can filter the results by various attributes: by Nominal Coil Voltage (2.7 V, 3 V, 5 V, 12 V, 24 V,…), Termination Style (PCB, PC Pin, Quick Connect,…) and Maximum Contact Current (from 1 A to 500 A) to name a few. You will be able to find the right PCB power relays, surface mount power relays, relay sockets, or power relays in SPST, DPDT, SPDT or DPST combinations for any circuit that may require a power relay.

Power Relays in Production Ready Packaging or R&D Quantities

We offer customers many of our power relay products in tube, tray or individual quantities that will help you avoid unneeded surplus. Many of our Power Relays are designed for specialized environments. The descriptions in the product detail overviews provide more information on High Capacity Noise Immune Power Relays or Polarized and non-Polarized Power Relay options.

In addition, Future Electronics offers a unique bonded inventory program, designed to avert the challenges resulting from the unpredictable supply of products containing raw metals and products with erratic or long lead times. Talk with your local Future Electronics branch and learn more about how you can avoid possible shortages today.
