Push-Pull Connector for Geophysical Exploration 2026: CBTG3FN-SMSM03-D720 and CBTG4FN-SMSM02-D720 Plugs for Field Survey and Industrial Power for Russian Customers

The CBTG3FN-SMSM03-D720 is a 3F push-pull connector for geophysical exploration — a compact 103F cable plug (approx. 13 mm) with 3 thick pins carrying up to 12 A of continuous current in handheld field instruments, joined in this order by the CBTG4FN-SMSM02-D720 4F plug (approx. 15 mm) with 2 pins rated 14-22 A for industrial power jumpers, both with rugged brass shells and gold-plated contacts. Every specification in this guide is backed by the field and factory interconnect engineering of Spring Technology.

Pain point: Connecting instruments that work where cables get dragged through mud or flexed beside CNC machines — where handheld environmental meters, portable spectrometers and laser distance measurers need compact rugged power links, and factory floors need modular power jump-cables that survive oil-mist and continuous flexing?

Core answer: For Russian customers, Spring Technology supplied two push-pull connector for geophysical exploration and field power links: the 3F CBTG3FN-SMSM03-D720 plug and the 4F CBTG4FN-SMSM02-D720 plug. The 103F 3-pin plug serves geophysical exploration and field surveying, built into flexible cable lines of handheld environmental meters, portable spectrometers and laser distance measurers, carrying up to 12 A of continuous current in a rugged brass shell. The 4F 2-pin plug serves industrial automation and heavy machinery power jumper lines, rated 14-22 A with massive dielectric isolation for modular power jump-cables on factory floors.

1. Technical Parameters & Engineering Standards

This field-and-factory pair combines the TGN.103F and TGN 4F waterproof plug platforms. The 3F plug packs thick 12 A contacts into a compact 13 mm body; the 4F plug uses a larger 15 mm frame for 14-22 A loads with strong dielectric isolation.

  • Latching Mechanism: Push-pull self-latching system (anti-vibration & shockproof)
  • Recommended Hardware: Spring Technology Circular Connector
  • Key Metric: 3F 12 A compact field plug (13 mm) + 4F 14-22 A power plug (15 mm)

2. Field and Factory Connector Design Highlights

One order, two worlds: mud-caked field instruments and oil-mist factory floors. The design highlights below are why this push-pull connector for geophysical exploration and power links is specified for both:

  • 3F compact field plug — the 103 size is a versatile, compact cable plug (approx. 13 mm outer diameter), easy to handle in the field.
  • 12 A continuous rating — squeezing only 3 pins into the 103 housing leaves relatively thick contacts that carry up to 12 A of continuous current.
  • Rugged brass shell — survives being dragged through mud on handheld environmental meters, portable spectrometers and laser distance measurers.
  • 4F high-current power plug — the mid-sized robust body (approx. 15 mm) splits its larger frame among only 2 thick pins, optimized for extremely high voltage or massive current loads (14-22 A) with massive dielectric isolation.
  • Industrial power jumper lines — bridges raw 24V/48V master DC current over heavily jacketed, shielded cables that withstand continuous automated mechanical flexing and factory oil-mist.
  • Gold-plated contacts — stable power delivery across field and factory environments.

3. 3F and 4F Series Connector Family Overview

The 103F and 104F shell sizes are part of Spring Technology’s waterproof TGN connector families. Together they cover compact field instruments and larger power equipment on a proven platform.

3.1 Available Configurations

  • 3F (103F) plugs: straight plugs in the compact 103 size, from 2 to 16 pins.
  • 4F (104F) plugs: straight plugs in the mid-size 104 frame, from 2 to 19 pins.
  • Termination: solder contacts across both sizes.
  • Keying: key N standard, with additional key options for segregation.

3.2 Customization Services

  • Custom pin allocations and part numbers (such as the CBTG3FN-SMSM03-D720 / CBTG4FN-SMSM02-D720) matched to each instrument’s power plan.
  • Heavily jacketed, shielded cable assemblies for factory power jumpers.
  • Flexible cable constructions for field instruments.
  • Key orientation selection to keep power circuits segregated.

4. Applications: Geophysical Survey and Industrial Power

From handheld field instruments to CNC spindle units, this push-pull connector for geophysical exploration and industrial power covers both ends of the cable.

4.1 Geophysical Exploration and Field Surveying

Built into the flexible cable lines of handheld environmental meters, portable spectrometers and laser distance measurers, the 3F plug survives mud and rough handling while the 3-wire layout handles standard low-voltage DC power.

4.2 Industrial Automation and Heavy Machinery Power Jumper Lines

The 4F plug fabricates modular power jump-cables for factory floors, automated sorting conveyors and CNC spindle units, bridging raw 24V/48V master DC current.

4.3 Flexing and Oil-Mist Resistance

The heavily jacketed, shielded cable paired with the 4F plug withstands continuous automated mechanical flexing and exposure to factory oil-mist.
