Fastronix 40/60A Waterproof Relay 6 Pack

I used this as a control from my Ignition switch for aftermarket TBI Fuel Injection. I have bought other relays here as well that fall apart and needed glue but this one is superior, The wire alone seems to be real copper.

I got these relays to replace the nitrous solenoid relays on my drag bike. The nitrous express relay costs triple what these cost, and as far as I can tell these are just as good a quality. I can use one now, and have the others for spares since they are fairly universal for a lot of things.They came really quickly, they work, and again the price was right!

Saved my soft wash pump.

I chose this device because I needed a relatively cheap, high transient load current relay. When I read that the coil resistance was “4096”, I was skeptical because that value happens to be 2 raised to the power of 12 (important for digital hardware folks and what are the odds?) - the actual value is significantly less. Although this might not be of concern if your application use’s automotive power systems, there are some applications where this may be important. Just FYI.For the record, the coil resistance is 80 ohms (not really surprising since most power relays of this type have that value), with an operating voltage of >6.3V and release voltage of <2.5V (your mileage may vary). Very low contact resistance, which is critical for the relatively high load currents.

Best relays I’ve ever used, hands down! I did a wiring setup in my truck for a daytime running light cutoff using the parking brake. Parking brake grounds the relay. I initially did it with another relay I had on the shelf from a wiring kit I never used. It was sending some weird backfeeding up the parking brake wire to the instrument cluster when I would deactivate the relay. I used a diode to fix that problem but then I noticed it was also causing flickering in my backup camera when the camera was on and I worked the parking brake. Tried another relay from a different brand, same thing.Grabbed one of my fastronix relays and problem solved. Quiet operation, very fair price, good quality piece, really can’t ask for more.

Good product and good price

They do exactly what they were made to do.

To replace failed oem parts on a Kawasaki Mule tilt bed hydraulic system.
