CBTG3FN Push-Pull Connector for Medical Endoscopes 2026: CBTG3FN-SMSM12-D720 and CBZL3FN-SFPM12-S000 for 4K/8K Endoscope Cable Assemblies for Russian Client

The CBTG3FN-SMSM12-D720 is a CBTG3FN push-pull connector for medical endoscopes — a 3F 12-pin plug with extremely fine 0.5 mm pin spacing, mated to the hermetic CBZL3FN-SFPM12-S000 socket to carry video differential signals, LED cold light power, temperature feedback and reset bus lines in one lightweight 4K/8K endoscope harness, with gold-plated contacts. Every specification in this guide is backed by the medical imaging interconnect engineering of Spring Technology.

Pain point: Building the cable assembly between a 4K/8K high-definition endoscope and its cold light source handle — where video differential signals, LED power, temperature feedback and reset bus lines must all fit into one lightweight harness with fine-pitch contacts that survive repeated reprocessing?

Core answer: For a Russian client, Spring Technology supplied a CBTG3FN push-pull connector for medical endoscopes: the CBTG3FN-SMSM12-D720 plug and the CBZL3FN-SFPM12-S000 socket, used in cable assemblies connecting 4K/8K high-definition endoscopes to cold light source handles. With their 12 pins featuring extremely fine spacing and diameters (only 0.5 mm), these connectors are ideally suited for integrating video differential signals for medical HD cameras, power supply lines for LED cold light sources, temperature sensor feedback logic and reset bus lines into a single, lightweight cable harness.

1. Technical Parameters & Engineering Standards

This endoscope cable connector pair combines the TGN.103F straight plug and the ZLN.103F hermetic socket, two 3F-family designs built for precision medical imaging links. The fine-pitch 12-pin layout packs video, power and sensing into one slim connector.

  • Latching Mechanism: Push-pull self-latching system (anti-vibration & shockproof)
  • Recommended Hardware: Spring Technology Circular Connector
  • Key Metric: 12 pins, 0.5 mm fine pitch; video + power + sensing in one lightweight harness

2. Medical Endoscope Connector Design Highlights

Modern endoscopy moves 4K/8K video, lighting and sensing through one slim cable. The design highlights below are why this CBTG3FN push-pull connector for medical endoscopes is specified for HD imaging systems:

  • 0.5 mm fine-pitch pins — 12 pins with extremely fine spacing and diameters (only 0.5 mm) pack a full signal set into a slim connector.
  • Video differential signals — supports differential video signal integration for medical HD cameras at 4K/8K resolution.
  • LED cold light power — power supply lines for LED cold light sources ride the same harness.
  • Temperature feedback and reset bus — temperature sensor feedback logic and reset bus lines complete the single lightweight cable harness.
  • Hermetic socket side — the ZLN hermetic socket protects the instrument connection from moisture and reprocessing fluids.
  • Gold-plated contacts — stable signal paths for high-bandwidth video and precise sensing.
