Anyone know of of a low cost idea for driving a reed switch? (The switch only, not an integrated switch+coil called a reed relay)
I'm thinking about some standard SMT coil like thingy. Maybe an air core inductor with 1000's of turns of very fine wire...
I plan on placing reed switches on one PCB and driving them from another physically close PCB. I briefly entertained the idea of making a coil inside the PCB but this is not a low cost approach and I can't get huge numbers of turns to meet the Ampere-Turn spec.
Any ideas? Think low cost! Anyone know of a standard inductor part with lots of turns that will possibly create a strong enough field?
The MFG's also offers the standard "test coils" but I've no idea about their cost but it would certainly work. Looking for novel/wacky ideas here that are low cost..
Thanks!
