CBTN1BG Push-Pull Connectors for Coating Thickness Gauges 2026: TN Body Style 1B Series 2-Pin and 3-Pin Plugs

The CBTN1BG-SMSM02-D62B and CBTN1BG-SMSM03-D62B are CBTN1BG push-pull connectors for coating thickness gauges — TN Body Style 1B Series straight plugs in two-contact and three-contact configurations, with push-pull locking, a cable collet and nut for bend-relief accessories, solder termination, a 1B platform cable opening range of 2.2–7.5 mm, IP50 protection, more than 5,000 mating cycles and operation from -45 °C to +125 °C. Every specification in this guide is backed by the portable inspection instrument interconnect engineering of Spring Technology.

Pain point: Connecting a coating measurement probe to a handheld gauge — where the probe is replaced when damaged or worn, contact count differs between instrument variants, the cable takes constant handling stress, and a straight exit is needed behind a compact housing?

Core answer: Spring Technology supplies two connector options that can be evaluated for compatible low-voltage cable connections in portable coating measurement equipment, offering compact cable interfaces, push-pull locking and flexible connection options for compatible sensor assemblies. Portable industrial coating thickness gauges measure the thickness of paint, protective coatings and other surface layers on metal components, helping quality-control teams verify coating consistency in automotive manufacturing, metal fabrication, industrial painting and corrosion-protection inspections. A typical gauge includes a probe, measurement electronics, a display and a cable or detachable interface connecting the sensor assembly to the main unit — and depending on the probe design, that interface may carry sensor signals, power or auxiliary control connections. The two-contact and three-contact configurations provide different interface options for designs with different wiring requirements.

Both of these CBTN1BG push-pull connectors for coating thickness gauges are built on the TN Body Style 1B Series, a compact straight-plug connector family for portable inspection instruments.

• Latching Mechanism: Push-pull locking mechanism (convenient connection and disconnection without a threaded coupling operation)
• Recommended Hardware: Spring Technology Circular Connector and custom cable assembly service
• Key Metric: 2 and 3 low-voltage contacts; push-pull locking; IP50; >5,000 mating cycles

Note: contact count alone does not determine whether a connector is suitable for a particular sensor. The full part number, connector dimensions, current rating, voltage rating, cable compatibility and mating receptacle must be checked before final selection, and the actual pin assignment must be confirmed from the probe and instrument schematics.

Coating probes are swapped and handled constantly. The design advantages below explain why these CBTN1BG push-pull connectors for coating thickness gauges suit portable probe interfaces:

• Different coating measurement probes have different electrical connection requirements: a two-contact interface may suit a simple circuit, while a three-contact configuration provides an additional contact for a compatible design. Having both options available gives equipment designers flexibility when developing different probe or instrument variants.

• Portable coating thickness gauges may be used at multiple inspection points across a production line or field inspection site, and a detachable connector makes it easier to disconnect a compatible probe cable for replacement, transportation or maintenance. The TN body style straight plug uses a push-pull locking mechanism which, when correctly paired with a compatible receptacle, supports convenient connection and disconnection without a threaded coupling operation — simplifying routine handling and reducing the time spent on cable changes during inspection work.

• The TN Body Style 1B Series connector has a straight plug configuration, useful when the instrument enclosure and cable route provide sufficient clearance behind the connector. A straight cable exit simplifies assembly and cable routing in certain portable measurement devices — while designers should still consider the required bend radius, strain relief, probe movement and the space available around the instrument housing.

• The plug configuration includes a cable collet and a nut intended for fitting a bend-relief accessory. These features secure the cable termination when the connector is assembled according to the manufacturer’s instructions, helping manage mechanical stress caused by repeated handling and probe repositioning. The complete cable assembly should be designed to avoid excessive pulling forces and sharp bends near the connector.

• Industrial inspection instruments require probe replacement when a sensor is damaged, worn or unsuitable for a particular measurement task. A detachable connector interface separates the probe assembly from the main instrument, making maintenance more convenient and allowing compatible replacement cables or probes to be installed without rewiring the entire device. For this benefit to be realised, the connector’s mating compatibility, contact arrangement and electrical characteristics must match the instrument design.

• The TN Body Style 1B Series .302 and .303 configurations represent different contact-count options within the 1B connector family, giving designers flexibility when specifying an interface for a particular electrical architecture. A manufacturer may evaluate the two-contact option for a simpler connection and the three-contact option when an additional circuit is required — a design possibility rather than a guaranteed application for every coating thickness gauge.

Portable coating measurement equipment benefits from practical cable connections, manageable mechanical layouts and serviceable probe assemblies. The CBTN1BG-SMSM02-D62B and CBTN1BG-SMSM03-D62B can be considered when a compatible low-voltage cable interface is required:

• Two contact-count options for different probe wiring requirements
• Push-Pull locking for quick probe cable changes
• Straight plug design for simple cable routing behind the housing
• Cable collet and nut for bend-relief and strain relief
• Detachable interface for replaceable probe assemblies
• 1B platform protection, temperature and endurance specifications

Before implementation, verify the exact connector specifications and mating receptacle. The connector should only be used within its published electrical and environmental limits.

The 1B shell belongs to Spring Technology’s push-pull connector family for portable instruments and industrial inspection equipment. The same platform serves these CBTN1BG push-pull connectors for coating thickness gauges and scales across pin counts and body styles.

• Plugs: TN Body Style straight plugs in .302, .303 and higher contact-count layouts.
• Receptacles: fixed sockets for panel mounting and cable-mount versions.
• Pin counts: 2–16 contacts across the 1B shell.
• Termination: solder with cable collet; PCB contact options on receptacle bodies.

• Custom contact allocations and part numbers (such as the CBTN1BG-SMSM02-D62B and CBTN1BG-SMSM03-D62B) matched to each instrument’s probe wiring.
• Probe cable assembly builds with defined cable opening ranges and bend relief.
• Shielding and grounding verification for measurement signal circuits.
• Mating receptacle selection support, including keying and contact-layout confirmation.

These are potential engineering applications for these CBTN1BG push-pull connectors for coating thickness gauges, based on the connector design — not verified installations in specific instrument brands or models:

Portable industrial coating thickness gauges and detachable coating measurement probe assemblies.

Protective coating inspection instruments and metal surface quality-control equipment.

Industrial paint thickness measurement systems used in automotive and metal-fabrication quality control.

This 1B connector delivery shows how Spring Technology serves portable inspection instruments — from the two-contact and three-contact options of the CBTN1BG-SMSM02-D62B and CBTN1BG-SMSM03-D62B to their cable collet, bend relief and push-pull locking, every detail was aligned with the customer’s coating thickness gauge requirements. Spring Technology also provides professional customization services for both push-pull connectors and cable assemblies, offering tailored solutions to meet your specific technical requirements.
