Valcom VC40R-4 4 Position Backplane Cable
Overview
The VC40R-4 is a 4-position backplane cable used inside Valcom rack-mount paging enclosures to interconnect card slots without discrete point-to-point wiring. It solves the internal wiring problem on multi-card paging racks: instead of running individual jumpers between each card position, the VC40R-4 provides a single harness that ties four backplane positions together, cutting install time and reducing wiring errors during rack build-out. At 0.03 lb, it adds negligible weight to a rack chassis assembly.
Compatibility
Built for Valcom rack-mount paging systems that use backplane card architecture, including installations pairing with Valcom Universal Paging Interface cards such as the VIP-4122-A12 and VIP-4122-A12-IC, and horn speaker deployments using the V-WGHORN-2 wire guard. Confirm your rack chassis uses a 4-position backplane slot layout before ordering — this cable is specific to that configuration and is not a universal card jumper.
Installation Notes
This is an internal rack component, not a field wiring harness — it connects backplane positions inside the enclosure rather than running to end devices. No tools or torque specs are specified for this cable; it is a factory-terminated harness intended for direct backplane connector engagement. Country of origin is the United States, which matters for installers on government or NDAA-scoped paging projects sourcing every rack component domestically.
Pair this with a broader Valcom paging catalog review when specifying a full rack build, and check the paging and intercom systems category for compatible interface cards and horn speakers. For projects speccing PoE-connected paging endpoints alongside rack hardware, a PoE switch planning guide is worth reviewing before finalizing the bill of materials. If you're building out a full enclosure, browse Valcom accessories for wire guards and mounting brackets that complete the rack.
