Canfield Connector's Series 7000 proximity switches
Series 7000 proximity sensors sense the position on 2 to 8 in. bore tie rod cylinders. They feature a self-adjusting clamp that grips standard NFPA as well as custom cylinders, which eliminates the need to stock individual clamps for different bore sizes. Custom circuits include 1 or 4 A reed switches, NO, NC or SPDT switch types, reed or electronic sensing elements and 120 Vac Hall sensor.
