Any thoughts on this relay?

baggystevo82 · 3rd October 2004, 01:00 PM

hello, ive been toying with the idea of a relayed passive pre for a while now (finally got fed up with swapping cables round all the time) and wondered what you all think of these relays from Maplin? heres the description:

Quote:

A sealed reedrelay suitable for useat voltages from 3·8V to22V with single-pole make or double-pole make actions. The highresistance coil enablesthe relay to be drivendirectly by 74 seriesICs and most logic buffers. At the same time the relay can switch up to 10VA. Contact Details (per contact) Max current: 1A Max voltage: 100V Max switching power: 10VA Contact resistance: 150m ohms max Operate time: 1ms max including bounce time Release time: 0·5ms max including bounce time Life: >1 million operations at full load

I'd like to be able to use these as they seem pretty cheap (88p each if over 25 are ordered) but don't know if they'd be good enough....anyone?
Cheers,
Steve

doesn't look like a Coto. I'd avoid it.

Hi Steve
I can't see any problem.

I have used similair relais in the past, works ok. You might have to mute the input of you amplifier first before switching sources to avoid any clicks.

Of course there are people who claim that the magnetic field cause changes in the signal ....

Hmm, it will be nicely regulated dc so hopefully the electromagnet wont be a problem, sure thats probably been debated to death elsewhere though, ill go have a look. Whats a Coto Brian?
Cheers all,
Steve
