SDC/Security Door Controls CA-UR4-8 Interface Cable

SDC CA-UR4-8 Interface Cable

Overview

The CA-UR4-8 is a dedicated interface cable engineered for the SDC UR4-8 multi-door access control controller. This cable bridges the UR4-8 unit and associated door control hardware, delivering the signal and power connectivity required in multi-door installations. Use this cable when deploying UR4-8-based systems with HID credential readers — it's the OEM connector that ensures proper signal integrity and eliminates guesswork in wiring.

Compatibility

The CA-UR4-8 is designed exclusively for the SDC UR4-8 controller. It integrates with HID reader infrastructure and door strike hardware managed by the UR4-8 unit. Security integrators and system installers deploying UR4-8-based access control systems will require this cable for complete hardware connectivity. Verify your UR4-8 model revision before ordering — cable pinouts are OEM-specific and substitutes from other manufacturers may result in wiring faults or reader timeouts.

Installation Notes

This is a factory-terminated interface cable — do not attempt field re-termination. Connect to the UR4-8 port as marked on the controller housing; incorrect orientation can prevent reader polling and door strike operation. Route cable away from high-voltage lines (120V+ AC) to avoid inductive noise coupling with reader communication. If cable routing exceeds 100 feet in noisy electrical environments, shield termination at the UR4-8 end may improve signal stability.
