CBZH0BG Push-Pull Connector for Thermocouple Calibrators 2026: 0B 7-Contact Panel Socket

The CBZH0BG-SFSM07-0000 is a CBZH0BG push-pull connector for thermocouple calibrators — a compact 0B fixed panel-mount receptacle with seven low-voltage contacts, a published rated current of 2.5 A, a push-pull self-latching mechanism, solder termination, nut fixing with a protruding shell, a chrome-plated brass metal housing, 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 temperature calibration equipment interconnect engineering of Spring Technology.

Pain point: Bringing several thermocouple signal lines and reference connections into a handheld calibrator — where the panel area is tiny, sensor cables are swapped between measurement points all day, and every contact pair sits in a microvolt-level signal chain?

Core answer: The CBZH0BG-SFSM07-0000 is a compact seven-contact circular receptacle designed for reliable low-voltage connections in professional electronic equipment, and can be considered for portable multi-channel thermocouple calibrators — its secure connection design supports sensor signal transmission and convenient cable management in industrial temperature measurement and calibration applications. Portable multi-channel thermocouple calibrators are used by industrial maintenance engineers, instrumentation technicians and calibration laboratories to test temperature measurement systems: these instruments can simulate thermocouple signals or measure signals generated by temperature sensors, and are commonly used to verify temperature controllers, inspect sensor performance and troubleshoot measurement circuits in industrial furnaces, heat treatment equipment and process control systems. A multi-channel calibrator may need to connect several low-voltage signal lines, reference inputs or auxiliary circuits, and this panel-mounted interface provides multiple connection paths for a suitably designed sensor or calibration cable assembly.

The CBZH0BG-SFSM07-0000 is a fixed panel receptacle on the compact 0B platform, offered with a seven-contact configuration and a protruding shell.

• Latching Mechanism: Push-pull self-latching system (secure mating during operation, quick disconnection when changing cables)
• Recommended Hardware: Spring Technology Circular Connector and custom cable assembly service
• Key Metric: 7 low-voltage contacts; 2.5 A published rating; 0B compact shell; IP50; >5,000 mating cycles

Note: IP50 indicates an indoor or otherwise protected-environment rating rather than water-ingress protection, and with a published rated current of 2.5 A this connector should be designed into low-voltage signal and compatible auxiliary circuits rather than treated as a high-power connector.

Calibration work is repetitive and precision-driven. The design advantages below explain why this CBZH0BG push-pull connector for thermocouple calibrators suits portable temperature calibration instruments:

• The CBZH0BG-SFSM07-0000 features seven low-voltage contacts, providing multiple connection paths for thermocouple signal lines, reference connections and auxiliary low-voltage circuits depending on the instrument’s electrical design. For portable calibration equipment, a multi-contact connector consolidates several signal connections into one compact interface.

• Calibration technicians frequently connect and disconnect sensor cables when testing different temperature measurement points. The push-pull self-latching mechanism helps secure the mating connector during operation while allowing quick disconnection when changing cables or performing maintenance — improving connection convenience during repeated calibration procedures.

• Portable thermocouple calibrators often have limited space for external connection interfaces, and the 0B shell size offers a compact circular connection solution — helping equipment designers integrate a multi-contact interface without requiring a large panel area.

• The CBZH0BG-SFSM07-0000 uses solder termination for its low-voltage contacts, allowing the connector to be integrated into a compatible internal wiring harness and supporting stable electrical connections when assembled according to the manufacturer’s soldering instructions.

• The connector uses a metal housing construction with a chrome-plated brass shell, providing a durable mechanical interface for portable instruments that are frequently handled, transported and connected during calibration work.

• The connector is configured with seven low-voltage contacts, and its published technical data lists a rated current of 2.5 A for this exact model — making it important to design the connection around low-voltage signal and compatible auxiliary circuits rather than treating it as a high-power connector.

Portable multi-channel thermocouple calibrators require dependable connections for sensor signals and calibration circuits, and their connectors should be compact, easy to operate and capable of supporting repeated connection cycles. This CBZH0BG push-pull connector for thermocouple calibrators combines seven low-voltage contacts, a push-pull locking mechanism, solder termination and a compact metal housing — characteristics that make it a potential choice for the external signal connection interface of portable temperature calibration instruments, offering manufacturers a practical way to organise multiple low-voltage connections through a single panel-mounted receptacle.

The 0B shell belongs to Spring Technology’s compact push-pull connector family for portable instruments and calibration equipment. The same platform serves this CBZH0BG push-pull connector for thermocouple calibrators and scales across plugs, protruding-shell sockets and standard panel sockets.

• Protruding-shell sockets: ZHG.0B fixed panel sockets, as used here, in 0B, 1B and 2B shells.
• Standard panel sockets: ZGG.0B fixed panel sockets with nut fixing and keying.
• Plugs: TGG.0B straight plugs, including a 307-series insert listed as the matching plug for this receptacle.
• Pin counts: 2–9 contacts across the 0B shell, with key G or keys A…M and R.

• Custom contact allocations and part numbers (such as the CBZH0BG-SFSM07-0000) matched to each instrument’s thermocouple wiring plan.
• Thermocouple extension cable assemblies using matched thermocouple alloys through the connector body.
• Panel cutout and mounting arrangement support for compact calibrator housings.
• Mating plug selection support, including keying and contact-layout confirmation.

The CBZH0BG-SFSM07-0000 can be considered for portable multi-channel thermocouple calibrators that require a compact and secure multi-contact connection interface — its seven low-voltage contacts, push-pull self-latching system, solder termination and metal housing support convenient integration into professional temperature measurement equipment. This connector shows how Spring Technology serves temperature calibration equipment, aligning a seven-contact protruding-shell 0B socket with the customer’s calibrator 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.

When selecting this connector, manufacturers should verify the thermocouple wiring arrangement, contact assignment, current requirements, mating plug and environmental conditions to ensure compatibility with the finished instrument.
