Tie Rod and Round Cylinder Proximity Sensors

7000 - High Current

The Canfield Series 7000 proximity sensors are used to sense position on cylinders. They accommodate 2 to 8 inch bore tie rod cylinders or 3/4 to 4 inch round cylinders. This proven design is rugged yet cost effective.
The Series 7000 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, and the industry’s first 120 VAC Hall sensor.
Awide range of enclosures and connector options are available. To reduce stocking requirements, two clamp options feature a self-adjusting clamp for NFPA and other tie rod cylinders from 2 to 8 inch bore. Another clamp option features a band clamp from 3/4 to 4 inch round cylinders.

7C - High Current

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.

7GL - General Location

The Canfield Connector 7GL is an expansion of the popular series 7000 “floating” clamp design, which adapts to NFPA tie rod linear actuators with 2 to 8 inch bore. this rugged magnetic proximity sensor can sense actuator position in stringent, general location applications. The switch features a robust, aircraft aluminum body, epoxy-filled, vibration and shock resistant, electronic circuit. Available in a normally open contact, the 7GL can switch current up to .5 Amps and has a voltage range of 0-120VAC/VDC 50/60 Hz.

7HL - Hazardous Location

The Canfield Connector 7HL is a rugged magnetic proximity sensor designed to sense actuator position in stringent, hazardous location applications. The switch features a robust, epoxy-filled, aircraft aluminum body, and has a vibration and shock resistant, electronic circuit. The 7HL is an expansion of the popular Series 7000 “floating” clamp design and will clamp on 2 to 8 inch bore NFPA tie rod linear actuators. This product is designed to operate in hazardous locations, this switch is CSA approved for Class I, Division 2, Groups A, B, C, and D; Class II, Division 2, Groups F and G; and Class III.

8000 - Low Current

The Canfield Connector Series 8000 Reed and Electronic sensors are compact units designed for sensing applications on round cylinders from 9/16" - 4" and tie-rod pneumatic cylinders from 3/4" - 8" bore. These sensors offer a wide voltage range from 0-120 VAC/VDC 50/60 Hz and high current capacity up to 0.5 Amps. They include high intensity indicator lights and a wide viewing angle. The sensor's small package can fit easily on the smallest cylinder without appearing too large. The Series 8000's design promotes ease of installation with a tight fit. Options include 9ft. PVC or 8mm quick connect male pigtail.

8WF - Weld Field Immune

The Canfield Connector Series 8WF weld field immune electronic sensors are compact magnetic sensors designed for sensing position magnetic pistons on pneumatic actuators while ignoring electro-magnetic pulses generated from AC weld fields. Designed for round type cylinders with diameters from 9/16" - 4" and tie-rod type cylinders from 3/4" - 8" bore, the 8WF features a rugged stainless steel and nylon enclosure and high current capacity up to 0.2 Amps and 24VDC input. Included in the sensor is a high intensity indicator light that can be seen from a wide viewing angle. The sensor's small package can fit easily on the smallest cylinder without appearing too large. The Series 8WF design promotes ease of installation with a tight fit. Options include 9ft. PVC or 8mm quick connect male pigtail.
