Reed Sensors Eye Mechanical Switch Apps

A new series of magnetically-operated reed proximity switches are said to be suitable replacements for mechanical switches, especially in wet and dirty applications. The MK4/5/13 Series reed sensors come in three mounting versions and can be mounted almost anywhere. The devices feature fully potted, hermetically sealed construction and are totally waterproof. Available with matching actuating magnets, the devices open and close with the introduction and removal of a magnetic field. The reed sensors are offered in five sensitivity classes from 5 to 30 AT, with switching voltages up to 400V and current up to 1.25A. They are available in normally-open and normally-closed SPDT configurations. Pricing is from $1.20 each, depending on version, termination requirements, and quantity.
