The FIS Cover Cop sensor uses fiber optic technology which is highly favorable over electrical contact switches. The Cover Cop requires no electrical power at its location so it can be used in remote areas where there often is no power. It can be used in flammable atmospheres where no type of spark is allowed. Most importantly, the FIS Cover Cop sensor has NO external moving parts. The electrical contact switches typically have a lever arm that makes contact with the lid or door that it is sensing, these levers often “stick” and fail due to corrosion. The FIS Cover Cop sensor is magnetic so it does not require contact with the surface it is sensing, eliminating corrosive failure.
