450 AC DC Parker Hannifin Corporation Fluid Control Solutions Europe General Catalogue FCSE/0112/UK V2.2 07/2022 EXPLOSION PROOF ELECTRICAL PARTS INCREASED SAFETY ELECTRICAL PARTS "nAc nCc" 495915 - ELECTRICAL PARTS 50 mm To Order a Coil choose Coil Ref + Voltage Code, example: 495915 for 24 VDC = 495915C2 This coil can be mounted with every Parker ATEX solenoid valves corresponding to the specified Coil Group. See column "Coil Group" within valve pages. Application: Control of solenoid valves in dangerous areas where explosion-proof protection - Ex nAc nCc IIC T3 is required. Benefits: Rotatable housing 360°, epoxy vernished steel with internal and external screw terminals for earth connection. Small size for ease of mounting in confined space. Simplifies conversion of existing equipment to hazardous area requirements.

This magnet retains the plunger in place. It stays in position even without current. Only an electrical impulse given to terminals A-C reserves the magnetic field. This magnetic field demagnetises the reversible magnet enough to allow the return spring to bring the plunger back to its initial position and close the valve. Switch: Switch on (terminals A-B): Minimum 50 ms (maximum 1 s) AC: Switch off (terminals A-C): Minimum 35 ms (maximum 1 s) Schema 4.0 COIL GROUP ZONE 2/22
