BBUP21UR Push-Pull Connector for Smart Navigation 2026: Custom Cable YH-C21046-1021U with RJ45 Ethernet and 48V/3A Power for US Client

The BBUP21UR-KSM816-D720 is a BBUP21UR push-pull connector for smart navigation — a plug at the heart of the custom cable assembly YH-C21046-1021U, which pairs a 1.5-meter cable with RJ45 Ethernet and 48V/3A power connectors, and mates with the BBUR21UR-KFE816-S25E panel-mount PCB socket. The breakout RJ45 connector transmits lossless Ethernet bus data while the 48V/3A line delivers up to 144 W of continuous power. Every specification in this guide is backed by the custom interconnect engineering of Spring Technology.

Pain point: Powering and networking high-consumption navigation equipment — where a computing terminal or high-power radio unit needs lossless Ethernet bus data and up to 144 W of continuous power through one integrated cable assembly?

Core answer: For a US client in smart navigation technology, Spring Technology designed the custom cable assembly YH-C21046-1021U. It consists of a BBUP21UR-KSM816-D720 plug, a 1.5-meter cable, and RJ45 and 48V/3A power connectors. The breakout RJ45 connector transmits lossless Ethernet bus data, while the 48V/3A high-capacity power line delivers up to 144 W of continuous power to high-consumption computing terminals or high-power radio units. The mating panel-mount PCB socket is the BBUR21UR-KFE816-S25E.

This smart navigation cable is a custom assembly built through Spring Technology’s Custom Cable Assembly service, combining a push-pull plug with network and power branches in one harness. The BBUP21UR-KSM816-D720 plug mates with the BBUR21UR-KFE816-S25E panel-mount PCB socket, which mounts at the equipment side.

• Latching Mechanism: Push-pull self-latching system (anti-vibration & shockproof)
• Recommended Hardware: Spring Technology Circular Connector
• Key Metric: RJ45 lossless Ethernet + 48V/3A (144 W) power in one 1.5 m cable assembly

Modern navigation systems combine heavy computing loads with high-power radios. The design highlights below are why this BBUP21UR push-pull connector for smart navigation is specified for these platforms:

• Lossless Ethernet branch — the RJ45 branch transmits lossless Ethernet bus data to the navigation computing terminal.
• 144 W continuous power — the 48V/3A high-capacity power line delivers up to 144 W for high-consumption computing terminals or high-power radio units.
• Single integrated harness — connector, 1.5-meter cable, RJ45 and power leads are combined in one custom assembly, simplifying installation.
• Matched plug and panel socket — the BBUP21UR-KSM816-D720 plug mates with the BBUR21UR-KFE816-S25E panel-mount PCB socket for a secure equipment interface.
• Balanced data and power routing — separate branches keep Ethernet signals clean from power transients.
• Gold-plated contacts — stable signal and power transfer across the assembly.

Spring Technology’s Custom Cable Assembly service combines automatic wire cutting, crimping, ultrasonic welding, potting and EMC assembly to deliver ready-to-use interconnect solutions. Cable assemblies like the YH-C21046-1021U are built to the customer’s exact connector, length and branch requirements.

• Connector bodies: push-pull plugs and matching panel-mount PCB sockets across the B, K, F and P series families.
• Branches: network (Ethernet/RJ45), power leads, sensor lines and control wires.
• Lengths and jackets: custom cable lengths with abrasion-resistant and shielded jacketing.
• Assembly features: overmolding, potting and EMC shielding options.

• Custom part numbers (such as the YH-C21046-1021U cable with BBUP21UR-KSM816-D720 plug and BBUR21UR-KFE816-S25E socket) with matched branch configurations.
• Power rating design, including 48V/3A style high-capacity feeds.
• Data branch configuration for Ethernet and other bus protocols.
• Assembly testing before delivery.

Navigation platforms increasingly merge networking and power in single assemblies. This BBUP21UR push-pull connector for smart navigation carries both.

High-consumption computing terminals receive both lossless Ethernet bus data and up to 144 W of continuous power through the YH-C21046-1021U assembly, which docks through the BBUR21UR-KFE816-S25E panel-mount PCB socket.

High-power radio units benefit from the 48V/3A power branch, keeping transmission hardware powered from a single cable run.

For smart navigation systems, combining RJ45 Ethernet and high-capacity power in one harness reduces cable count and installation complexity.

This custom cable delivery for the US client shows how Spring Technology integrates data and power for navigation platforms — from the BBUP21UR-KSM816-D720 connector to the RJ45 and 48V/3A branches of the YH-C21046-1021U assembly, every detail was aligned with the customer’s smart navigation requirements. Spring Technology’s Custom Cable Assembly service combines automatic wire cutting, crimping, ultrasonic welding, potting and EMC assembly to deliver ready-to-use interconnect solutions.
