Connectors for Ultrasonic Flow Meters 2026: CBTN1BA-SMSM06-D52B Six-Contact Lanyard-Release Plug

Spring Technology supplies connectors for ultrasonic flow meters — the CBTN1BA-SMSM06-D52B is a six-contact straight cable-mounted plug in the TN body style, with a push-pull coupling mechanism and lanyard-release design, solder termination, cable collet fixation, a 2.2–7.5 mm cable opening range, IP50 protection, key G or keys A…M and R, operation from -45 °C to +125 °C, vibration resistance of 10~20,000 Hz at 15 g and more than 5,000 mating cycles. Every specification in this guide is backed by the flow measurement equipment interconnect engineering of Spring Technology.

Pain point: Moving a clamp-on flow meter from pipe to pipe — where transducer cables are connected and released dozens of times per survey, the release mechanism must work while wearing gloves, and an IP50 interface has to be kept clear of dripping water and condensate?

Core answer: Spring Technology offers the CBTN1BA-SMSM06-D52B for evaluation as a potential cable-interface component for portable ultrasonic flow measurement equipment, supporting reliable sensor connections, convenient cable handling and efficient industrial flow measurement, subject to confirmation of the exact electrical and mechanical requirements. Portable ultrasonic flow meters are widely used in industrial maintenance, water management, HVAC commissioning and process monitoring, measuring fluid flow through a pipe using ultrasonic signals and often allowing technicians to inspect flow conditions without cutting into the pipeline when a suitable clamp-on measurement system is used. Reliable connections between the meter, sensor cables and external transducers are important for efficient field operation.

As one of Spring Technology’s connectors for ultrasonic flow meters, the CBTN1BA-SMSM06-D52B is a TN body style cable plug in the 1B shell size, offered with a six-contact configuration and lanyard release.

• Latching Mechanism: Push-pull coupling with lanyard release (connect and release without a threaded-coupling operation)
• Recommended Hardware: Spring Technology Circular Connector and custom cable assembly service
• Key Metric: 6 low-voltage contacts; IP50; 2.2–7.5 mm cable opening; >5,000 mating cycles

Note: IP50 is a protected-environment rating and does not indicate protection against water ingress — the exact configuration and the complete mated assembly must be verified before use in wet environments.

Field flow surveys are repetitive and hands-on. The design advantages below explain why these connectors for ultrasonic flow meters suit portable flow measurement equipment:

• The CBTN1BA-SMSM06-D52B provides six low-voltage contacts and, depending on the meter’s circuit design, a multi-contact interface accommodates several signal or auxiliary circuits within one connector. For a portable ultrasonic flow meter these circuits may relate to sensor signals, auxiliary connections or control functions. The actual pin assignment must be designed according to the instrument manufacturer’s electrical architecture.

• The TN body style connector uses a push-pull coupling mechanism with a lanyard-release design, making connection and disconnection of a compatible cable assembly convenient during routine instrument setup and maintenance — with the exact release and mating arrangement verified for the selected configuration. Field technicians often move measurement instruments between pipelines and inspection locations, so a convenient interface reduces unnecessary handling steps when changing cables or servicing the instrument.

• The CBTN1BA-SMSM06-D52B is a straight cable-mounted plug, and the related standard configuration supports solder termination so the cable assembly can be configured for the intended electrical interface. A dedicated cable-mounted connector helps equipment manufacturers create a defined connection between the meter enclosure and external sensor cable — with proper cable termination, strain relief and assembly workmanship remaining essential to long-term reliability.

• Ultrasonic flow measurement relies on appropriate sensor placement, correct instrument configuration and reliable signal acquisition, and a properly selected connector helps maintain the intended electrical connection between the meter and its compatible sensor assembly. This matters when technicians perform repeated measurements at multiple points along a pipeline — although the connector alone does not determine measurement accuracy, since sensor installation, pipe conditions, calibration and the meter’s signal-processing design also affect results.

• Portable flow meters must accommodate electronic circuitry, a display, controls and sensor connections within a manageable enclosure, and a compact circular connector helps organise the external cable interface and simplify equipment integration. Before selecting the CBTN1BA-SMSM06-D52B, manufacturers should confirm its exact cable diameter range, mating compatibility, contact ratings and environmental protection requirements.

The proposed application of these connectors for ultrasonic flow meters may be considered in portable instruments used for:

• Industrial water pipeline inspection: connecting compatible transducer cables to instruments used to evaluate water flow.
• HVAC system commissioning: supporting cable connections in portable instruments used to check water circulation in heating and cooling systems.
• Process equipment maintenance: providing a detachable interface for flow measurement equipment used during routine industrial servicing.
• Building utility monitoring: helping organise sensor connections for field measurements in water distribution and facility management systems.

These are potential equipment-design applications — not claims that the exact CBTN1BA-SMSM06-D52B model has been confirmed in a particular commercial flow meter.

The TN body style belongs to the push-pull connector family behind these connectors for ultrasonic flow meters, serving portable instruments and field equipment. The same platform serves these connectors for ultrasonic flow meters and scales across shell sizes and contact counts.

• TN body plugs: lanyard-release plugs in the 0B, 1B and 2B shells, including the six-contact 1B layout used here.
• TG body plugs: standard straight plugs where a conventional push-pull release is preferred.
• Receptacles: ZGG fixed panel sockets and ZGG free sockets for the mating side of the interface.
• 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 CBTN1BA-SMSM06-D52B) matched to each instrument’s wiring plan.
• Transducer cable assemblies with defined cable openings and strain relief for clamp-on sensors.
• Shielding and grounding support for low-level ultrasonic signal circuits.
• Mating receptacle selection support, including keying and release-arrangement confirmation.

The CBTN1BA-SMSM06-D52B connector may be evaluated for portable ultrasonic flow meters that require a multi-contact cable interface — its six low-voltage contacts and push-pull lanyard-release design support organised sensor connectivity and convenient field servicing when correctly integrated. This connector shows how Spring Technology serves flow measurement instrumentation, aligning a compact 1B lanyard-release plug with the customer’s field 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.

Before production, equipment manufacturers should verify the complete part number, connector mating compatibility, cable diameter, contact configuration, electrical ratings and environmental protection requirements — these checks help ensure the selected connector meets the needs of the specific flow measurement instrument.
