CBZG1BG Push-Pull Connector for Fiber Fusion Splicers 2026: 1B 16-Contact PCB Socket

The CBZG1BG-SFPM16-0000 is a CBZG1BG push-pull connector for fiber fusion splicers — a 1B circular panel receptacle with sixteen low-voltage contacts, straight PCB termination contacts, a rated current of 2 A, a published maximum contact resistance of 8.7 mΩ, published minimum shielding performance of 75 dB at 10 MHz and 40 dB at 1 GHz, a push-pull self-locking mechanism, front-panel mounting with an M12 panel drill hole, a mechanical endurance of 5,000 mating cycles and IP50 protection. Every specification in this guide is backed by the optical instrument interconnect engineering of Spring Technology.

Pain point: Landing an external control cable straight onto the main board of a handheld splicer — where the enclosure has no room for an internal harness, arc and heater circuits sit inches away, and the panel interface must survive production testing plus years of field servicing?

Core answer: The CBZG1BG-SFPM16-0000 can be considered for portable optical fiber fusion splicers. A fusion splicer joins two optical fibers by aligning their ends and applying a controlled electric arc to fuse them, using optical cameras to capture fiber images while the image processing system evaluates fiber positions and sends control signals to precision motors — after alignment the electrode system generates an arc, and a heater may protect the finished splice with a heat-shrink sleeve. A typical machine contains optical camera and image acquisition modules, image processing and main control circuits, fiber alignment and focusing motors, electrode monitoring and arc control circuits, heating module control circuits, and user interface and status monitoring electronics. The receptacle can be integrated into the front panel and connected directly to the internal PCB through its straight PCB contacts, with the sixteen contacts assigned to low-voltage sensor signals, motor status feedback, auxiliary control lines and other electronic interfaces according to the equipment circuit design.

The CBZG1BG-SFPM16-0000 is a front-panel receptacle on the 1B platform, using straight PCB contacts for direct board integration.

• Latching Mechanism: Push-pull self-locking mechanism (quick-release connection without rotating a coupling nut)
• Recommended Hardware: Spring Technology Circular Connector and custom cable assembly service
• Key Metric: 16 low-voltage contacts; straight PCB contacts; 2 A; 8.7 mΩ; M12 panel hole; 5,000 cycles; IP50

Note: the connector should be used for suitable low-voltage circuits rather than the high-voltage electrode discharge path or the high-current heater power circuit. Actual signal integrity also depends on PCB layout, grounding, cable quality and the design of the complete electronic system, and final selection should consider the PCB footprint and mechanical mounting dimensions as well as the pin assignment.

Board-level integration removes a whole harness from the design. The design advantages below explain why this CBZG1BG push-pull connector for fiber fusion splicers suits compact precision optical instruments:

• The CBZG1BG-SFPM16-0000 features straight PCB termination contacts, allowing the receptacle to connect directly to a printed circuit board and reducing the need for separate internal wire harnesses between the panel connector and the control electronics. For fusion splicers this simplifies the electrical connection between the external interface and the main control board, and supports a more organised internal layout in compact portable instruments.

• The connector provides 16 low-voltage contacts in a compact 1B configuration. A fusion splicer contains several electronic modules that exchange control and feedback signals, and the 16-contact configuration gives designers flexibility to allocate connections for auxiliary sensors, control signals, status feedback and other low-voltage circuits — reducing the number of separate connector interfaces required on the equipment housing.

• The CBZG1BG-SFPM16-0000 uses Spring Technology’s push-pull self-locking mechanism, so the compatible plug can be connected and disconnected through a simple push-pull operation — useful during equipment assembly, maintenance, cable replacement and production testing, without requiring operators to repeatedly rotate a coupling nut.

• The connector has a maximum contact resistance of 8.7 mΩ according to the published specifications, helping establish reliable electrical connections between the external cable assembly and the internal control PCB — important for electronic control and monitoring circuits that depend on consistent signal connections.

• The published specification lists minimum shielding performance of 75 dB at 10 MHz and 40 dB at 1 GHz for this connector, helping reduce electromagnetic coupling when the connector is integrated with appropriate cable shielding, PCB grounding and enclosure design — beneficial in a fusion splicer when routing low-voltage control and monitoring signals near electronic drive circuits, while overall electromagnetic compatibility must still be verified at equipment level.

• The CBZG1BG-SFPM16-0000 uses a front-panel mounting structure with an M12 panel drill hole. This compact arrangement suits portable instruments where internal space is limited, providing an accessible external interface while maintaining a direct PCB connection behind the panel.

• The published specification lists a mechanical endurance of 5,000 mating cycles for this model — useful for electronic instruments requiring regular cable connection, inspection, calibration or replacement of external accessories, and the reusable interface helps reduce maintenance complexity and supports repeated equipment testing during manufacturing and servicing.

Optical fiber fusion splicers require precise coordination between optical imaging, motor positioning, electronic control and monitoring circuits, and their internal architecture must support reliable connections while keeping the instrument compact. This CBZG1BG push-pull connector for fiber fusion splicers combines 16 low-voltage contacts, straight PCB termination and a push-pull locking mechanism — making it a potential connection solution for the external control and auxiliary signal interfaces of portable splicers, where direct PCB integration simplifies internal wiring and the push-pull mechanism makes cable connection and maintenance more convenient.
