Overview

The NBX‑966 is a passive open-style junction. Three labelled connector banks (A / B / C) sit on a single mounting platform with through-hole flanges at each end — the box is screwed straight onto a bracket or panel inside a cab or enclosure and harness branches plug into A, B and C in any combination the program needs.

Engineering details

  • Three connector banks, labelled A / B / C, individually keyed
  • Open-style platform — no top cover, no gasket; sealing is provided by the surrounding enclosure or harness boot
  • Pure passive construction — no fuse holders, no relay sockets
  • Through-hole mounting flanges at both ends of the platform
  • 9–32 VDC compatible — voltage rating set by the wiring inside, not by the box itself
  • Working temperature −40 to +85°C

Because the NBX‑966 is open, it is intended for placement inside a vehicle cabin, dashboard, control box or larger sealed enclosure — not for direct outdoor or chassis-bottom placement. For chassis-bottom or wheel-arch use, specify the sealed NBX‑965 sealed junction box or the NBX‑968 sealed electrical box instead.

Configuration notes

Each connector bank accepts a small family of compatible automotive housings and terminals; program-specific housing P/N, terminal P/N and pin-out are confirmed against the customer harness drawing at quotation. The NBX‑966 platform itself is one stable mechanical part — what runs through it is set by the customer's wiring plan.

Choosing the NBX‑966: open three-bank block or sealed junction

When the junction already sits inside a protected space — a cab, dashboard or control-box interior — the choice between the NBX‑966 and the sealed-cover NBX‑965 comes down to branch density and how often you expect to re-open the point. The NBX‑966 carries three keyed connector banks (A / B / C) against the NBX‑965's two inlets, so it consolidates more harness branches at one place, and its open platform lets a technician plug or unplug a branch during build or service without lifting a gasketed cover.

The trade-off is that the NBX‑966 provides no sealing of its own and leans on the surrounding cabin or enclosure for ingress protection. If the same junction needs its own cover, or has to move toward the chassis rail or outdoors, specify the sealed-cover NBX‑965 (IP54) or the IP65 NBX‑968 sealed electrical box instead. Whether the point should also carry fuses or relays is a separate decision — see the junction vs fuse vs relay box guide.
