CBTG1BG Connectors for Electrostatic Spray Coating Controllers 2026: 1B 4-Contact and 5-Contact Cable Plugs

The CBTG1BG-SMSM04-D52B and CBTG1BG-SMSM05-D620 are CBTG1BG connectors for electrostatic spray coating controllers — 1B straight cable plugs with four and five low-voltage contacts, published rated currents of 10 A and 9 A respectively, push-pull locking, cable collet fixation, a specified cable outside diameter range of 4.30–5.20 mm, IP50 protection, solder termination and a published mating endurance of 5,000 cycles. Every specification in this guide is backed by the industrial coating equipment interconnect engineering of Spring Technology.

Pain point: Wiring the low-voltage control and signal side of a spray coating controller — where circuit counts vary between machine variants, cables are replaced during servicing, the cable must stay clearly separate from the applicator’s high-voltage circuits, and the interface must never be mistaken for a spray-voltage connection?

Core answer: Spring Technology offers these connectors as potential options for suitable low-voltage control and signal interfaces, supporting push-pull locking, multiple contact configurations, compact cable connections and convenient maintenance for industrial coating equipment. Industrial electrostatic spray coating systems are used in automotive manufacturing, metal finishing, furniture production and other industrial coating processes, controlling spraying parameters and coordinating spray applicator operation to help achieve consistent coating quality. A typical controller manages spray voltage settings, operating modes, system status and communication with other equipment — and depending on the system architecture, electrical interfaces may connect the controller to external control panels, monitoring devices or compatible auxiliary modules. These connectors should only be used in circuits for which their ratings and environmental characteristics are suitable, and they are not intended to replace the dedicated high-voltage connections required by electrostatic spray applicators.

1. Technical Parameters & Engineering Standards

Both connectors are built on the TG 1B straight plug platform, a compact circular connector family for industrial control equipment.

  • 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: 4 and 5 low-voltage contacts; 10 A and 9 A published ratings; IP50; 5,000 mating cycles

Note: the published ratings should not be interpreted as a guarantee that every contact can carry the maximum rated current simultaneously under all operating conditions — actual current capacity depends on the manufacturer’s derating guidance, conductor dimensions, ambient temperature, contact loading and the electrical design.

2. Connector Design Highlights for Spray Coating Controllers

Coating lines run hard and are serviced on schedule. The design advantages below explain why these CBTG1BG connectors for electrostatic spray coating controllers suit low-voltage control interfaces:

2.1 Multiple Contacts for Control and Signal Connections

  • Four low-voltage contacts in the CBTG1BG-SMSM04-D52B and five in the CBTG1BG-SMSM05-D620 let equipment designers choose a connector based on the number of electrical circuits required. For a coating controller, suitable circuits might include auxiliary control signals, status feedback or other low-voltage connections: the four-contact version suits a simpler interface, while the five-contact version provides an additional contact for designs needing another circuit. The actual pin assignment must be defined by the equipment manufacturer.

2.2 Push-Pull Locking for Convenient Maintenance

  • Industrial coating equipment requires regular inspection, cable replacement and maintenance. The push-pull locking mechanism lets a compatible plug be connected and released without repeatedly rotating a threaded coupling, simplifying routine cable handling and helping technicians disconnect suitable interfaces during servicing. Correct mating and proper operating procedures remain essential for reliable use.

2.3 Cable-Mounted Design for Flexible Equipment Layouts

  • Both models are straight cable plugs with cable collet fixation and a specified cable outside diameter range of 4.30–5.20 mm. This construction supports organised cable routing between a controller and compatible external equipment, and a suitable cable assembly keeps connections accessible during installation and troubleshooting. Engineers should confirm cable dimensions, conductor size, strain relief and routing requirements before choosing the final assembly.

2.4 Different Current Ratings for Different Circuit Requirements

  • The published rated current is 10 A for the four-contact model and 9 A for the five-contact model — useful reference values when evaluating compatible low-voltage circuits, provided the derating guidance, conductor dimensions, ambient temperature and contact loading are respected.

2.5 Repeatable Connections During Equipment Service

  • The published specifications list a mating endurance of 5,000 cycles for these models — useful where compatible cables are connected and disconnected repeatedly during maintenance or configuration changes. A properly selected connector interface helps standardise cable connections across compatible controller assemblies, while installation quality, handling and adherence to the specified operating conditions remain important for long-term performance.

2.6 Shielding Support for Industrial Control Interfaces

  • The published specifications list shielding performance for both models. In an industrial control system, suitable shielding and grounding help manage electromagnetic interference affecting compatible signal circuits; the actual result depends on the complete cable assembly, connector termination, grounding arrangement and equipment layout. In electrostatic spray systems, engineers must also follow the controller manufacturer’s electrical safety instructions and separation requirements for high-voltage circuits.

3. Four-Contact vs Five-Contact Models

The primary difference between these models is the number of contacts and the corresponding electrical ratings. The four-contact model may be considered where a compatible four-contact interface is sufficient, while the five-contact model suits circuit designs requiring an additional contact.

  • CBTG1BG-SMSM04-D52B: four contacts, rated current of 10 A, and documented USB 2.0 capability.
  • CBTG1BG-SMSM05-D620: five contacts, rated current of 9 A.

Although the four-contact model is listed for USB 2.0, this capability should not be assumed for the five-contact model or for a complete system without checking the relevant device documentation.

4. Important Design Considerations

Before integrating either of these CBTG1BG connectors for electrostatic spray coating controllers into a coating controller, engineers should verify:

  • The required contact count and electrical pin assignment
  • Compatibility with the exact mating receptacle
  • Operating voltage, current and conductor specifications
  • Cable outside diameter and cable collet compatibility
  • Environmental protection requirements for dust, moisture and cleaning procedures
  • Grounding, shielding and separation from high-voltage circuits
  • Whether the IP50 rating is suitable for the installation environment

These checks help ensure that the selected connector is appropriate for the intended interface and does not compromise the safety requirements of the coating system.
