CBZE2BG Push-Pull Connector for Programmable DC Power Supplies 2026: 2B Series 2-Contact 20.5 A Output Socket for High-Power Power Equipment

The CBZE2BG-SMSM02-0000 is a CBZE2BG push-pull connector for programmable DC power supplies — a 2B series fixed panel-mounted receptacle with 2 low-voltage contacts, a 2 mm contact diameter, 22–14 AWG wire compatibility, a 20.5 A rating, maximum contact resistance of 3.3 mΩ, rear-panel mounting with an M15 panel drill hole and a PPS insulator. Every specification in this guide is backed by the high-current power equipment interconnect engineering of Spring Technology.

Pain point: Building a high-current DC output interface onto a programmable power supply — where the connector sits in the output power path, so resistance, voltage drop, heat and mechanical stability all limit what the instrument can deliver to a device under test?

Core answer: Spring Technology supplies the CBZE2BG-SMSM02-0000, a 2B series fixed panel-mounted receptacle serving as a CBZE2BG push-pull connector for programmable DC power supplies. These supplies are used in laboratories, automated test systems, electronics manufacturing, power electronics development and industrial testing to provide controlled DC voltage and current to a device under test, and they require a reliable interface between internal power circuitry and the external output cable or test fixture. The two-contact configuration suits a dedicated positive/negative DC output interface, while fixed rear-panel mounting lets the connector become an integrated part of the power supply enclosure rather than a loose cable connection.

This power supply connector is built on the ZEG.2B fixed socket platform, a mid-size circular connector family for professional equipment power and signal interfaces.

• Latching Mechanism: Push-pull self-latching system (quick connection and release without threaded coupling)
• Recommended Hardware: Spring Technology Circular Connector
• Key Metric: 2 low-voltage contacts at 2 mm; 20.5 A rated current; max. 3.3 mΩ contact resistance; M15 panel mounting

The output interface is the last component in the power path — and often the most thermally stressed. The design advantages below explain why this CBZE2BG push-pull connector for programmable DC power supplies suits high-current output interfaces:

• A 20.5 A rating suits power supply applications requiring significantly more current than ordinary instrumentation or signal connectors — including power semiconductor testing, motor controller development, battery-related test systems, industrial electronics testing, DC motor testing and power module evaluation — giving designers substantial current capability for the external DC output interface.

• For a conventional DC output, the two contacts can be assigned to the positive and negative paths. This simple configuration avoids unnecessary signal contacts and suits cases where the primary requirement is reliable power transmission rather than multi-channel signal connectivity.

• Because the connector forms part of the output power path, connector resistance directly affects performance. A low-resistance interface helps reduce voltage drop, connector power dissipation, localised heating and additional resistance in the output circuit — especially relevant at higher output currents.

• As a fixed panel rear-mounted receptacle with an M15 panel drill hole, the connector suits bench-top and rack-mounted supplies and integrates directly into the rear panel, leaving the front panel free for display, voltage and current controls, status indicators, communication ports and protection controls.

• A supply may be connected to different test fixtures or devices under test during laboratory development and production testing. The push-pull mechanism connects and releases the output cable quickly without a threaded coupling operation, improving operator convenience when test configurations change frequently.

• Support for AWG 22 to AWG 14 conductors with a maximum solid conductor size of 1.5 mm² makes higher-current power cable assemblies practical, so connector and cable can be designed together as part of the external power-output path. The actual allowable current must still be determined by the complete connector, cable, thermal and system design.

• Programmable supplies are frequently used in engineering laboratories and automated test environments where output cables are connected and disconnected repeatedly, so a 5,000 mating cycle endurance rating helps support long-term serviceability when the equipment is regularly reconfigured.

• Minimum shielding performance of 75 dB at 10 MHz and 40 dB at 1 GHz helps designers manage electromagnetic coupling around the external connection interface where high-power supplies operate alongside sensitive measurement equipment, control systems and communication interfaces.

• Specifications include 100 g shock resistance and 15 g vibration resistance over 10~20000 Hz, useful when equipment is transported between laboratories, production areas or automated test stations, and adding mechanical margin for equipment subjected to repeated handling.

• The PPS insulator is an important part of the connector’s electrical performance, providing electrical separation between contacts and the connector housing while supporting the specified voltage-test performance.

The 2B shell is part of Spring Technology’s push-pull connector family, used in power equipment, test and measurement, industrial and professional applications. The same platform serves this power supply socket and scales across pin counts and contact variants.

• Sockets: ZEG.2B fixed socket variants, including rear-panel versions with M15 panel mounting.
• Pin counts: 2 to 26 contacts across the 2B shell, including the 2-contact high-current layout.
• Termination: solder and cable-mount options with cable collet.
• Conductor range: high-current configurations supporting up to AWG 14 with 1.5 mm² solid conductors.

• Custom contact configurations and part numbers (such as the CBZE2BG-SMSM02-0000) matched to each supply’s output path.
• High-current DC output cable assembly design with the required conductor size.
• Rear-panel and rack-mount integration support, including M15 panel preparation.
• Verification support for output safety and insulation requirements.

Laboratory power equipment lives on detachable output connections. This CBZE2BG push-pull connector for programmable DC power supplies serves those interfaces.

The primary application: a programmable supply providing controlled DC voltage and current to electronic devices under test through a dedicated positive/negative output interface.

Rear-panel mounting suits rack-mounted power equipment with the output cable at the rear of the chassis, and industrial programmable DC sources use a two-contact high-current connector for detachable output connections.

Engineering platforms developing power converters, semiconductor systems and industrial controllers benefit from a compact detachable high-current power interface.

This 2B connector delivery shows how Spring Technology serves laboratory and industrial power equipment — from the 20.5 A contacts and 3.3 mΩ resistance of the CBZE2BG-SMSM02-0000 to its M15 rear-panel mounting and PPS insulation, every detail was aligned with the customer’s programmable DC power supply requirements. Spring Technology also provides professional customization services for both push-pull connectors and cable assemblies, offering tailored solutions to meet your specific technical requirements.
