The vendor has modified the sensors with its Quickon connector so that they can handle two wires. As a result, the user can connect multiple sensors with each other—similar to a bus—which is designed to make cabling easier than connecting each sensor individually. All that is needed is a two-wire cable that is simply cut wherever the sensor must be mounted. With the Quickon connectors, only the coating of the two-wire cable must be shortened, not the insulation of each wire. The contact is established by tightening a coupling ring, which creates a gas-proof electrical connection that is designed to be impervious to shock and vibration.
