CBTG1BG Push-Pull Connector for Acoustic Imaging Cameras 2026: 1B 7-Contact Shielded Plug

The CBTG1BG-SMSM07-D52B is a CBTG1BG push-pull connector for acoustic imaging cameras — a 1B straight cable plug with seven low-voltage contacts, a push-pull self-locking mechanism, published minimum shielding performance of 75 dB at 10 MHz and 40 dB at 1 GHz for this connector configuration, a nut for fitting a cable bend relief, a supported cable outside diameter of 4.30–5.20 mm, wire sizes from AWG 30 to AWG 22, a shielded construction, IP50 protection, operation from -45 °C to +125 °C and more than 5,000 mating cycles. Every specification in this guide is backed by the industrial inspection equipment interconnect engineering of Spring Technology.

Pain point: Wiring a microphone array to the processing unit in a handheld camera — where the array needs power, control and synchronisation, the instrument is carried from compressor rooms to switchgear, and the signal electronics sit next to motors and variable-frequency drives?

Core answer: The CBTG1BG-SMSM07-D52B can support reliable electrical connections in portable industrial acoustic imaging cameras for leak detection and predictive maintenance. These cameras are advanced inspection instruments used to locate compressed air leaks, gas leaks, vacuum leaks and partial discharge in electrical equipment — and unlike conventional ultrasonic detectors that mainly provide sound measurements, an acoustic imaging camera uses a microphone array and beamforming technology to identify the direction and location of abnormal sound sources, displaying the acoustic information as a sound map overlaid on a visible-light image. A portable camera generally consists of a microphone array, signal acquisition electronics, an image-processing unit, a display and a power supply, and the connector can be considered for the electrical interface between the microphone array assembly and the main processing unit.

The CBTG1BG-SMSM07-D52B is a straight cable plug on the 1B platform, offered with a seven-contact configuration.

• Latching Mechanism: Push-pull self-locking mechanism (secure connection, quick release during setup and maintenance)
• Recommended Hardware: Spring Technology Circular Connector and custom cable assembly service
• Key Metric: 7 low-voltage contacts; shielded; 75 dB / 40 dB; cable 4.30–5.20 mm; AWG 30–22; IP50

Note: the shielding figures are connection-level references — combined with properly shielded cables and suitable grounding the connector can contribute to electromagnetic compatibility, but signal integrity depends on the complete assembly. IP50 is not a waterproof rating.

Acoustic cameras listen to faint sources in loud electrical surroundings. The design advantages below explain why this CBTG1BG push-pull connector for acoustic imaging cameras suits portable inspection instruments:

• Portable acoustic imaging cameras integrate microphone arrays with electronic processing modules that require reliable connections for power distribution and control signals. The seven low-voltage contacts allow multiple circuits in one circular connector, simplifying the wiring arrangement between internal modules — but for arrays with dozens or hundreds of MEMS sensors the connector must be used according to the actual interface architecture, since it is not intended to replace the complete high-channel-count microphone data interface.

• Acoustic imaging cameras are frequently carried between production lines, compressor rooms, substations and other inspection locations. The push-pull self-locking mechanism maintains a secure connection while allowing technicians to connect or disconnect the cable quickly during equipment setup and maintenance — particularly useful for portable instruments that require repeated connection cycles.

• Industrial acoustic imaging equipment contains sensitive signal acquisition and processing electronics, and interference from motors, variable-frequency drives, switchgear and other electrical equipment may affect the measurement environment. The published specification lists minimum shielding performance of 75 dB at 10 MHz and 40 dB at 1 GHz for this connector configuration — contributing to electromagnetic compatibility and helping protect signal integrity when combined with properly shielded cables and suitable grounding.

• Portable inspection instruments are frequently handled during field operations, and their cables may be bent or repositioned as technicians move around industrial equipment. The D52B configuration includes a nut for fitting a cable bend relief, protecting the cable exit area from excessive bending and mechanical stress — a suitable bend-relief accessory helps improve the durability of the cable assembly during repeated handling.

• The CBTG1BG-SMSM07-D52B belongs to the 1B connector series and has a straight cable plug configuration. Its compact circular design helps engineers organise cable connections in portable acoustic imaging instruments where internal space and cable routing are important design considerations, and it supports cable outside diameters of 4.30–5.20 mm with wire sizes from AWG 30 to AWG 22.

Reliable electrical connections are important for portable acoustic imaging cameras because their microphone arrays and processing electronics must work together during real-time inspection. This CBTG1BG push-pull connector for acoustic imaging cameras offers:

• Seven low-voltage contacts: supports multiple low-voltage power and control circuits.
• Push-pull self-locking: allows quick connection and disconnection during field maintenance.
• Shielded construction: helps reduce electromagnetic interference when properly integrated into the cable assembly.
• Cable bend-relief provision: helps protect the cable termination from mechanical stress.
• Compact 1B design: supports organised wiring in portable inspection equipment.

These features make the connector worth evaluating for internal electrical interfaces and detachable cable assemblies in industrial acoustic imaging cameras.

The 1B shell belongs to Spring Technology’s push-pull connector family for industrial instruments and inspection equipment. The same platform serves this CBTG1BG push-pull connector for acoustic imaging cameras and scales across plugs, panel sockets and PCB sockets.

• Plugs: TG 1B straight plugs with cable collet, including the seven-contact layout used here.
• Panel sockets: ZGG.1B, ZEG.1B and ZCG.1B fixed panel sockets.
• PCB sockets: ZX 1B sockets with PCB contacts.
• Pin counts: 2–16 contacts across the 1B shell, with key G or keys A…M and R.

• Custom contact allocations and part numbers (such as the CBTG1BG-SMSM07-D52B) matched to each camera’s array interface.
• Shielded array and module harness builds with 360° screen termination and bend relief.
• Grounding and EMC support for microphone array and synchronisation circuits.
• Mating receptacle selection support, including keying and contact-layout confirmation.

Portable industrial acoustic imaging cameras help maintenance teams locate compressed air leaks, vacuum leaks and partial discharge without relying solely on conventional sound measurements — and to support reliable connections between the microphone array assembly and the main electronic unit, a suitable circular connector is an important part of the system design. With seven low-voltage contacts, push-pull locking, shielding performance and a cable bend-relief provision, the CBTG1BG-SMSM07-D52B is a potential connector solution for portable acoustic imaging equipment, subject to electrical and environmental compatibility checks. This connector shows how Spring Technology serves predictive maintenance equipment, aligning a shielded 1B plug with the customer’s camera requirements, and the company also provides professional customization services for both push-pull connectors and cable assemblies, offering tailored solutions to meet your specific technical requirements.
