CBTG2BG Push-Pull Connector for AOI Lighting Controllers 2026: 2B Series 19-Contact 5 A Plug for Multi-Channel Inspection Lighting Systems

The CBTG2BG-SMSM19 19-contact plug is a CBTG2BG push-pull connector for AOI lighting controllers — a 2B series straight low-voltage plug with 19 contacts, push-pull locking, solder termination, a rated current of 5 A, the 2B platform cable opening range of 1.5–9.7 mm, IP50 protection and shielding of at least 75 dB at 10 MHz. Every specification in this guide is backed by the machine vision interconnect engineering of Spring Technology.

Pain point: Coordinating ring lights, bar lights, coaxial lights and backlights from one controller — where channel enables, intensity control, external triggers and status feedback all share a compact interface, and the wiring runs next to switching supplies, drives and conveyors?

Core answer: Spring Technology supplies the CBTG2BG-SMSM19, a straight 19-contact low-voltage plug in the 2B series that can be evaluated for auxiliary control and signal connections in AOI lighting controller systems requiring compact, reliable and serviceable electrical interfaces. An automated optical inspection lighting controller manages illumination sources such as ring lights, bar lights, coaxial lights and backlights, and by adjusting lighting channels and coordinating trigger signals it helps an inspection system capture images under suitable illumination conditions. Inside an industrial inspection system the controller needs connections for channel control, trigger signals, status feedback and auxiliary low-voltage circuits.

2. AOI Lighting Controller Connector Design Highlights

Inspection lighting must be controlled channel by channel, cycle after cycle. The design advantages below explain why this CBTG2BG push-pull connector for AOI lighting controllers suits multi-channel lighting control interfaces:

2.1 Nineteen Contacts for Multi-Channel Control

  • Nineteen low-voltage contacts in one circular connector give designers flexibility to combine multiple compatible circuits in a single cable interface — covering lighting channel enable signals, illumination intensity control, external trigger signals, controller status feedback, auxiliary sensor signals and low-voltage power and ground circuits. The exact pin assignment depends on the controller architecture.

2.2 Push-Pull Locking for Efficient Equipment Maintenance

  • AOI production lines often require inspection recipes to be changed, lighting modules to be replaced and equipment to be serviced. The push-pull self-latching mechanism enables quick connection and release without repeatedly rotating a threaded coupling, simplifying these procedures and reducing the time technicians spend disconnecting and reconnecting compatible modules. The locking mechanism also helps maintain a secure connection during normal operation when the connector is correctly mated.

2.3 Compact Integration for Controller Cabinets

  • A multi-channel lighting controller must accommodate power electronics, channel drivers, control boards and communication interfaces within a limited enclosure. The 2B circular format provides a single multi-contact interface for compatible low-voltage circuits, helping organise wiring and reduce the number of separate connectors required for selected control functions. Supporting cable openings from 1.5 to 9.7 mm across the 2B platform gives the cable assembly a defined mechanical interface; correct panel clearance, cable bend radius, strain relief and connector orientation should be considered during integration.

2.4 Five-Ampere Rating for Suitable Auxiliary Circuits

  • A published 5 A rated current with support for conductors from AWG 30 to AWG 22 suits suitable low-voltage auxiliary circuits, subject to contact loading, ambient temperature, cable specifications and applicable derating requirements. In an AOI lighting controller the connector may be evaluated for control electronics, auxiliary circuits or other compatible low-current interfaces — not for the main current of high-power lighting channels without a detailed assessment.

2.5 Shielding for Electrically Noisy Manufacturing Environments

  • AOI systems may operate near switching power supplies, motor drives, conveyors and automated production equipment that can create electromagnetic interference affecting signal wiring. Minimum shielding performance of 75 dB at 10 MHz and 40 dB at 1 GHz supports reliable signal transmission when integrated with appropriate cable shielding, grounding and enclosure bonding. The EMC of the complete lighting controller depends on the overall system design, not the connector alone.

2.6 Mechanical Durability for Repeated Connection Cycles

  • Lighting controllers and inspection stations require repeated cable disconnection during maintenance, production-line reconfiguration or equipment replacement. Specified for up to 5,000 mating cycles with shock resistance up to 100 g and vibration resistance up to 15 g over 10~20000 Hz, the connector suits industrial equipment undergoing routine servicing. Proper installation remains important: cable strain relief and routing should prevent unnecessary mechanical stress on the connector and its soldered terminations.

3. Why Choose CBTG2BG-SMSM19 for AOI Lighting Controllers?

The connector offers several features worth considering when designing multi-channel lighting control equipment:

  • 19 low-voltage contacts: supports multiple compatible control and auxiliary circuits.
  • Push-Pull self-latching: facilitates quick connection and disconnection.
  • 5 A rated current: capacity for suitable auxiliary circuits within specified limits.
  • Shielded construction: supports EMC-conscious cable assembly design.
  • Defined cable compatibility: accommodates cable openings of 1.5–9.7 mm across the 2B platform.
  • Mechanical durability: specified for repeated mating, shock and vibration.

These features help designers create organised, serviceable electrical interfaces for AOI lighting control systems.
