LS-800-5 Series Single-Point Level Switches are ideal for large or small tanks or where access to the inside is impractical or impossible. LS-800-5 Series units mount completely outside of the tank at the level actuation point and is offered in brass or stainless-steel housing 3/4" NPT ports.
Yes, very low currents (< 5ma) can prevent “cleaning” of the contacts or not have enough energy to maintain low contact resistance. 5ma is likely a good minimum for our standard 20 VA switch. But you also want enough voltage. Approximately, 5V, 5ma is a good minimum. For low current switching we recommend a 10 VA reed switch which can better handle lower loads. (1ma for example).
What is the life expectancy of a reed switch?
A reed switch is extremely rugged and designed to operate reliably for many years, under ideal conditions, up to about 2 million cycles. To achieve maximum service life, reed switches benefit from protected electrical supply.
LS-800 Series Multi-Point Level Switch is capable of supporting larger, more buoyant floats, and is physically stronger than other metallic models for better reliability in contaminated or turbulent media. LS-800 offers SPST or SPDT switches, and...
