CBTG1BG Connectors for CNC Laser Interferometer Systems 2026: 1B 7-Contact Plug and Panel Receptacle for Machine Tool Calibration

The CBTG1BG-SMSM07-D720 cable plug and CBZG1BG-SFSM07-0000 panel receptacle are CBTG1BG connectors for CNC laser interferometer systems — a 1B straight plug with seven low-voltage contacts, a cable collet and a published rated current of 7 A, paired with a front-mounted 1B panel receptacle of the same seven-contact layout, both with push-pull locking, IP50 protection, solder termination, operation from -45 °C to +125 °C and 1B platform cable opening ranges of 2.2–7.5 mm. Every specification in this guide is backed by the precision measurement equipment interconnect engineering of Spring Technology.

Pain point: Keeping the measurement head, signal-processing unit and controller reliably connected while a laser interferometer moves between machine tools — where cables are mated and unmated repeatedly during calibration, the controller enclosure needs a defined panel entry point, and seven circuits must be allocated before a single measurement is taken?

Core answer: Spring Technology offers these connectors as potential connector options for precision measurement equipment of this type, subject to verification of their exact mating compatibility, supporting seven-contact connectivity, push-pull locking and panel-mounted interfaces for reliable connections. Precision CNC machine tools require accurate positioning to manufacture components within tight dimensional tolerances, and even small positioning errors in a machine’s linear axes can affect machining accuracy, repeatability and final product quality. A laser interferometer system helps engineers evaluate machine tool performance by measuring parameters such as linear positioning accuracy, repeatability, straightness and angular errors, typically including a laser source, optical measuring components, signal-processing electronics and a computer or controller for data analysis — with electrical connections between the measurement head, signal-processing unit and control equipment that must remain stable during setup, calibration and repeated measurement procedures.

Both parts are built on the 1B platform: the TG straight plug body and the ZGG fixed panel socket body.

• Latching Mechanism: Push-pull locking (quick connection and release with a compatible mating connector)
• Recommended Hardware: Spring Technology Circular Connector and custom cable assembly service
• Key Metric: 7 low-voltage contacts; 7 A published plug rating; IP50; >5,000 mating cycles

Note: the rated current should not be interpreted as permission to carry 7 A through every contact simultaneously under all conditions — permitted current depends on the manufacturer’s derating guidance, ambient temperature, conductor size, contact loading and system requirements. Seven contacts do not automatically mean a connector can carry every required laser, encoder or data signal.

Calibration equipment is set up, moved and reconnected. The design advantages below explain why these CBTG1BG connectors for CNC laser interferometer systems suit precision measurement interfaces:

• Seven low-voltage contacts accommodate multiple electrical circuits within a single connector interface, and depending on the system design these circuits may be allocated to compatible signal, control, identification or auxiliary functions. Consolidating several connections into one interface simplifies cable routing and equipment integration — with the actual pin assignment determined by the system engineer.

• Laser interferometer systems may be repositioned between different machine tools or measurement locations, and technicians may need to connect and disconnect cables several times during installation and calibration. The push-pull locking mechanism is designed for quick connection and release with a compatible mating connector, making routine setup more convenient than a coupling arrangement requiring repeated screw-thread rotation. A properly matched pair also provides a consistent connection interface during normal handling and maintenance.

• The CBZG1BG-SFSM07-0000 is a fixed, front-mounted panel receptacle. A panel-mounted interface provides a defined connection point on a laser interferometer controller, measurement electronics enclosure or calibration instrument, helping organise external cabling and simplifying access during servicing. The final panel design should follow the manufacturer’s mounting dimensions and the enclosure’s mechanical requirements.

• The CBTG1BG-SMSM07-D720 is a straight cable plug with a cable collet, suitable for cable-mounted connection designs where the cable connects to a compatible panel receptacle. In a machine tool calibration environment, a well-planned cable assembly helps technicians arrange connections between measurement components and the processing unit while keeping the interface accessible. Cable selection, strain relief, bend radius and installation routing remain important to avoid unnecessary mechanical stress during repeated equipment movement.

• The published datasheet lists a rated current of 7 A for the CBTG1BG-SMSM07-D720, relevant when evaluating the connector for compatible auxiliary or control circuits. Sensitive measurement signals should also be evaluated for electrical noise, grounding, shielding and signal-integrity requirements before the connector is selected.

• Machine tool calibration involves repeated measurement runs and periodic maintenance. A connector designed for repeated mating helps make equipment connections more consistent over its service life when installed and handled correctly. Before specifying this plug and receptacle as a pair, engineers should confirm the exact connector keying, contact arrangement, cable collet compatibility and mechanical mating dimensions with the supplier.

When evaluating these CBTG1BG connectors for CNC laser interferometer systems, equipment manufacturers should review:

• Mating compatibility: confirm that the exact CBTG1BG-SMSM07-D720 plug is compatible with the CBZG1BG-SFSM07-0000 receptacle.
• Electrical design: check contact assignments, operating voltage, current and signal requirements.
• Cable specification: confirm conductor size, cable outside diameter, shielding and bending requirements.
• Environmental protection: verify whether the IP50 rating is sufficient for the machine tool environment, especially where coolant, oil, dust or moisture may be present.
• System-level measurement performance: validate grounding, cable shielding and signal quality to avoid compromising measurement reliability.

The connector’s suitability depends on the complete measurement system rather than the connector model alone.

The 1B shell belongs to Spring Technology’s push-pull connector family for precision measurement and industrial control equipment. The same platform serves these CBTG1BG connectors for CNC laser interferometer systems and scales across plugs, sockets and contact variants.

• Plugs: TG 1B straight plugs including bend-relief versions and the 7-contact layout used here.
• Sockets: ZGG.1B fixed panel receptacles in matching contact counts.
• Pin counts: 2–16 contacts across the 1B shell.
• Keying: key G or keys A…M and R to prevent mismating across system variants.

• Custom contact allocations and part numbers (such as the CBTG1BG-SMSM07-D720 and CBZG1BG-SFSM07-0000) matched to each system’s wiring plan.
• Cable assembly builds with defined cable opening ranges, strain relief and bend relief.
• Shielding and grounding verification for laser and encoder signal circuits.
• Mating plug / receptacle selection support, including keying and contact-layout confirmation.

These are potential engineering applications for these CBTG1BG connectors for CNC laser interferometer systems, based on the connector configuration — not verified installations in specific instrument brands or models:

Laser interferometer systems for CNC machine tool calibration and linear positioning verification.

Interface connections between measurement heads, signal-processing electronics and analysis controllers.
