The Canfield Series 7C proximity sensors are used to sense position on pneumatic actuators equipped with magnetic pistons from 2" to 8" bore. This proven design is rugged yet cost effective. All switches feature a self-adjusting clamp that grips standard NFPA and custom cylinders eliminating stocking requirements of many clamps for different bore sizes. The Series 7C boasts the largest number of custom circuits to match applications found in the market. Examples include; 1 or 4 Amp reed switches, normally open, normally closed or SPDT switch types, reed or electronic sensing elements in the same package style, not to mention the industry’s first 120 VAC Hall sensor. The low cost 7C features a ½” conduit hub and wire lead to meet stringent electrical codes in certain regions and applications.

Compatible with IS (Intrinsically Safe) barriers

  • Temperature Range: Operational from -20° to +80°C.
  • Shock: Operational up to 30G (11 ms.) reeds only. Not applicable for electronics.
  • Vibration: Operational up to 20 G (10 - 55Hz) reeds only. Not applicable for electronics.
  • Sensitivity and orientation: 85 gauss parallel minimum required for proper operation, as measured on sensor surface. Size of sensing area depends on size and strength of magnet and thickness of cylinder wall.
