SDC 482R-KIT SPDT Push Plate Actuator 4.5 Round

Overview

The SDC 482R-KIT is a momentary SPDT push plate actuator housed in a 4.5-inch round stainless steel faceplate. It mounts recessed, surface box, or bollard-mounted and operates at 28VDC, making it a direct fit for multi-door access control systems. This unit handles 1 Amp @ 28VDC (resistive load), sufficient for relay coils and strike control circuits in standard access control deployments. Use this where you need a hardwired momentary contact switch integrated into an entry door or controlled portal — not a networked credential reader, but the physical actuator that triggers the unlock signal downstream.

Compatibility

The 482R-KIT pairs with any access control panel or controller that accepts a 28VDC momentary SPDT circuit. Its push-plate form factor is designed for corridor-, vestibule-, and entrance applications where occupants must manually activate egress or request entry. The wireless-compatible design (confirmed for 482R variants) allows integration with wireless access control gateways if your system supports remote triggering. Check your existing panel documentation for available relay inputs — this is a simple hard-contact device, not a protocol-dependent reader.

Installation Notes

Faceplate depth is 7/8 inch — verify your surface box or recessed cavity accommodates this dimension. Stainless steel 18-gauge construction resists corrosion but requires standard electrical wiring (24–28VDC supply, ground, and NO/NC contact runs back to your panel). No special tools beyond a screwdriver and wire strippers. The SPDT contact rating is the limiting factor: confirm your strike or relay coil draws under 1 Amp at 28VDC — if higher, add an intermediate relay. ADA-compliant mounting heights and force thresholds are application-dependent; confirm with your local code authority and access control architect.
