VRC brackets and couplers provide for a flush mounting of the positioner to the actuator, and offers some shielding to the actuator shaft and bearing area from contamination.
A single coupler (part number VM0029N-Mach) is used on all Namur style actuators with 20 mm (.787 inch) and 30 mm (1.18 inch) shaft heights.
Namur style actuators with a 20 mm (.787 inch) shaft height require Part Number VA0006-2.6 Bracket and Part Number VM0029N-Mach Coupler.
There are three brackets available for Namur style actuators with 30 mm (1.18 inch) shaft heights. The clearance required to fit over the shaft boss area will determine which bracket to use. They have 1.6 inch clearance (PN VK03), 2.6 inch clearance (PN VK03-2.6), and 4.0 inch clearance (PN VK03-4.0).
Brackets and couplers are available for Non-Namur actuators. Contact VRC with your requirements.
