CBTG1BG Connectors for Multi-Angle Spectrophotometers 2026: 1B 6-Contact Cable Plug and Panel Receptacle for Color Measurement

The CBTG1BG-SMSM06-D52B cable plug and CBZG1BG-SFSM06-0000 panel receptacle are CBTG1BG connectors for multi-angle spectrophotometers — a 1B straight cable plug with six low-voltage contacts, a cable collet, a specified cable outside diameter range of 4.30–5.20 mm and a published rated current of 7 A, paired with a 1B fixed front-mounted panel receptacle of the same six-contact layout, both with push-pull locking, IP50 protection, solder termination and a published mating endurance of 5,000 cycles. Every specification in this guide is backed by the precision optical measurement equipment interconnect engineering of Spring Technology.

Pain point: Interfacing a handheld spectrophotometer’s optics, electronics and accessories — where the housing must hold optical components, a display and a battery, the instrument travels between paint lines and laboratories, and every contact allocation affects a measurement chain that has to stay repeatable?

Core answer: Spring Technology offers these connectors as potential options for suitable electrical interfaces in this equipment category, supporting six-contact connectivity, push-pull locking and panel-mounted integration for industrial color measurement equipment. Portable multi-angle spectrophotometers evaluate the color and appearance of metallic paints, pearlescent coatings and other special-effect finishes by measuring reflected light at different observation angles, helping manufacturers identify color variations that may not be apparent from a single viewing angle. In automotive manufacturing, multi-angle color measurement helps quality-control teams assess painted body panels, bumpers, mirror housings and door handles — supporting paint matching, production inspection and communication of color specifications between suppliers and manufacturers. A typical instrument combines an optical measurement system, light source, detector, signal-processing electronics, a display and a data interface, and the actual application must be validated against the instrument’s wiring, signal and mechanical requirements.

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 mechanism (a compatible plug connects and releases without repeatedly rotating a threaded coupling)
• Recommended Hardware: Spring Technology Circular Connector and custom cable assembly service
• Key Metric: 6 low-voltage contacts; 7 A published plug rating; IP50; 5,000 mating cycles

Note: the 7 A rating should not be interpreted as a guarantee that every contact can continuously carry 7 A at the same time under all operating conditions — actual current capacity depends on derating guidance, conductor size, ambient temperature and the number of simultaneously loaded contacts. Six contacts do not automatically guarantee compatibility with a particular sensor, communication protocol or data interface.

Color instruments travel and are recalibrated. The design advantages below explain why these CBTG1BG connectors for multi-angle spectrophotometers suit portable optical measurement interfaces:

• Both models feature six low-voltage contacts, accommodating multiple electrical circuits through a single connector interface. Depending on the instrument design, these circuits may be allocated to compatible power, control, status or auxiliary signal functions; combining suitable circuits in one connection simplifies cable routing and helps organise the internal layout of a portable spectrophotometer. The contact assignment must be established by the equipment manufacturer.

• Portable color measurement instruments are frequently moved between inspection stations, production areas and laboratories, so a convenient connector interface helps technicians manage cable connections during setup and maintenance. The push-pull locking mechanism lets a compatible plug be connected and released without repeatedly rotating a threaded coupling — simplifying routine handling when an instrument uses detachable cables or serviceable external modules. Correct mating compatibility and appropriate handling are essential for dependable operation.

• The CBZG1BG-SFSM06-0000 is a fixed, front-mounted panel receptacle providing a defined electrical connection point on a suitable instrument enclosure or control unit. For portable spectrophotometers, a dedicated panel interface keeps external connections organised and accessible — useful when designing compact housings that must accommodate optical components, electronic circuits, a display and battery or power connections. The final enclosure design should follow the manufacturer’s panel-mount dimensions and mechanical requirements.

• The CBTG1BG-SMSM06-D52B is a straight cable plug with a cable collet and a published cable outside diameter range of 4.30–5.20 mm. This provides an option for cable-mounted connections between compatible equipment interfaces, and a suitably designed cable assembly supports orderly routing and easier access during service. Engineers should verify actual cable diameter, conductor size, bend radius and strain-relief requirements before specifying the assembly.

• The published datasheet lists a rated current of 7 A for the CBTG1BG-SMSM06-D52B — relevant when evaluating the connector for suitable auxiliary or control circuits, subject to derating guidance, conductor size, ambient temperature and the number of simultaneously loaded contacts. Sensitive optical measurement electronics may also require careful grounding, shielding and signal-integrity evaluation.

• The published specifications list a mating endurance of 5,000 cycles for this plug — useful where a compatible connector interface is disconnected and reconnected during routine servicing. For color measurement equipment, a well-designed detachable connection simplifies cable replacement and access to serviceable modules, though long-term reliability still depends on correct installation, compatible mating components and operation within the manufacturer’s specified conditions.

Before using these CBTG1BG connectors for multi-angle spectrophotometers, equipment designers should confirm:

• Mating compatibility: verify the exact plug and receptacle keying, contact arrangement and mechanical dimensions.
• Electrical requirements: check voltage, current, contact assignment and any applicable derating requirements.
• Cable specifications: confirm cable outside diameter, conductor size, shielding and strain relief.
• Environmental conditions: evaluate dust, moisture, cleaning procedures, vibration and handling requirements.
• Signal integrity: validate grounding and shielding where sensitive optical measurement electronics are involved.
• System performance: confirm that the complete instrument meets its color measurement repeatability and accuracy requirements.

The connector can support the electrical interface, but the accuracy of color measurement depends on the optical system, calibration, electronics, software and overall instrument design.

The 1B shell belongs to Spring Technology’s push-pull connector family for precision optical measurement and industrial inspection equipment. The same platform serves these CBTG1BG connectors for multi-angle spectrophotometers and scales across plugs, sockets and contact variants.

• Plugs: TG 1B straight plugs with cable collet, including the 6-contact layout used here.
• Sockets: ZGG.1B fixed front-mounted panel receptacles with nut fixing and keying.
• Pin counts: 2–16 contacts across the 1B shell.
• Keying: key G or keys A…M and R to prevent mismating across instrument variants.

• Custom contact allocations and part numbers (such as the CBTG1BG-SMSM06-D52B and CBZG1BG-SFSM06-0000) matched to each instrument’s wiring plan.
• Cable assembly builds with defined cable opening ranges and strain relief.
• Shielding and grounding verification for detector and data signal circuits.
• Mating plug / receptacle selection support, including keying and contact-layout confirmation.

These are potential engineering applications for these CBTG1BG connectors for multi-angle spectrophotometers, based on the connector configuration — not verified installations in specific instrument brands or models:

Color and appearance measurement instruments for metallic paints, pearlescent coatings and special-effect finishes.

Quality-control stations assessing painted body panels, bumpers, mirror housings and door handles.

Color difference measurement instruments used for paint matching and specification communication between suppliers and manufacturers.
