High/Low Temperature Proximity Switches

08/03/2010 4:29 AM

Hi all

I have a need for a small/sub-miniature magnetic proximity switch, 4 to 6mm diameter cylindrical package would be ideal, that can withstand -55 to +150degC and also some severe shock and vibration.

Anyone used something similar recently and can make a recommendation? The electrical properties of the switch aren't desperately important just at the moment as we're at the development stage - could be NO, NC or changeover. Quantities up to say a dozen at the moment, just to get us started.

Thanks very much in advance

Do you prefer a magnetic base to attach (sticks to metal) or one that detects magnets as material?

Sorry that was unclear - the proximity switch would be activated by the presence nearby of the magnet.

Hi Dan,

Have you tried DigiKey?

Look here. Looked like there might be something there for you.
