CBTG2BG Push-Pull Connector for DC Motor Armature Testers 2026: 2B 2-Contact 20.5 A Cable Plug

The CBTG2BG-SMSM02-D82B is a CBTG2BG push-pull connector for DC motor armature testers — a 2B straight cable plug with two low-voltage contacts, male solder contacts, a published rated current of 20.5 A, a push-pull locking system, solder termination, a cable collet supporting cable outside diameters of approximately 7.30–8.20 mm, a metal housing with PPS insulator, IP50 protection and a specified endurance of up to 5,000 mating cycles. Every specification in this guide is backed by the motor test equipment interconnect engineering of Spring Technology.

Pain point: Pushing a controlled test current into an armature winding through a detachable lead — where the cable is heavy, the technician moves between motors all shift, and the joint must stay low-resistance while the fixture is swapped for different motor sizes?

Core answer: The CBTG2BG-SMSM02-D82B is a two-contact cable plug that can be used in portable DC motor armature testing equipment — its two low-voltage contacts, 20.5 A rated current and push-pull locking system provide a practical connection solution for detachable electrical test cables. DC motors are widely used in industrial machinery, material handling systems, manufacturing equipment and transportation applications, and during maintenance and quality inspection technicians need to evaluate motor armature winding resistance, electrical continuity and other winding-related characteristics — a portable armature test instrument lets maintenance engineers perform these electrical inspections without relying on a large stationary test system. The connector can be considered for the detachable cable interface between the portable instrument and an external motor test fixture, with its two contacts assigned to a compatible two-wire test-current circuit or auxiliary connection; test systems requiring separate voltage-sensing leads must provide those sensing connections independently.

The CBTG2BG-SMSM02-D82B is a straight cable plug on the 2B platform, offered with a two-contact configuration for dedicated test circuits.

• Latching Mechanism: Push-pull locking system (mating and release without threaded coupling operations)
• Recommended Hardware: Spring Technology Circular Connector and custom cable assembly service
• Key Metric: 2 low-voltage contacts; 20.5 A published rating; cable range 7.30–8.20 mm; IP50; up to 5,000 mating cycles

Note: the 20.5 A rating supports compatible higher-current test circuits only when the cable size, operating temperature, duty cycle and complete electrical design remain within the specified limits — IP50 is not a water-immersion rating.

Motor test leads carry real current and get handled daily. The design advantages below explain why this CBTG2BG push-pull connector for DC motor armature testers suits portable test equipment:

• The CBTG2BG-SMSM02-D82B features two low-voltage contacts, a configuration suited to a dedicated two-wire electrical connection between the tester and an external motor test fixture. Equipment manufacturers can assign the contacts according to the instrument’s circuit architecture, creating a straightforward and organised cable interface.

• Some DC motor testing procedures require controlled electrical current to evaluate winding characteristics. With a published rated current of 20.5 A, the connector can support compatible higher-current test circuits when cable size, operating temperature, duty cycle and the complete electrical design remain within the specified limits — making it a potential option for portable motor testing equipment requiring a robust detachable electrical connection.

• Maintenance technicians may need to inspect multiple motors or connect different test fixtures during a working shift. The push-pull self-latching mechanism enables convenient mating and release without threaded coupling operations, simplifying repeated connection procedures and supporting efficient field maintenance.

• The connector uses solder termination, allowing manufacturers to integrate it into customised motor testing cables, with wiring configured to match the instrument’s output circuit, external test fixture and measurement requirements — valuable when designing specialised test leads for different DC motor models.

• The CBTG2BG-SMSM02-D82B supports cable outside diameters of approximately 7.30–8.20 mm, and its cable collet secures the cable within the connector assembly, reducing the risk of cable movement placing excessive mechanical stress on the soldered connections — particularly useful for portable test instruments whose cables are frequently handled and repositioned.

• The connector features a metal housing and a PPS insulator, and its push-pull design is specified for up to 5,000 mating cycles — characteristics that support repeated connection and disconnection in suitable industrial testing environments.

Portable DC motor armature test instruments require reliable cable connections for electrical testing and routine maintenance. This CBTG2BG push-pull connector for DC motor armature testers offers:

• Two low-voltage contacts for dedicated electrical test circuits.
• 20.5 A rated current for compatible higher-current applications.
• Push-pull locking for convenient cable connection and removal.
• Solder termination for customised test cable assemblies.
• Cable compatibility with an outside diameter of 7.30–8.20 mm.
• Metal housing and PPS insulation.
• IP50 protection for suitable indoor and controlled environments.
• A specified mechanical endurance of up to 5,000 mating cycles.

These features make the connector a potential solution for detachable test cable assemblies used in portable DC motor armature testing equipment.

• Free sockets: DHG.2B free sockets for cable-to-cable extensions, also listed as a matching option.
• Pin counts: 2–26 contacts across the 2B shell, with key G or keys A…M and R.

• Custom contact allocations and part numbers (such as the CBTG2BG-SMSM02-D82B) matched to each instrument’s output circuit.
• High-current test lead assemblies sized to the required conductor cross-section, with collet clamping.
• Kelvin (four-wire) sensing arrangements built as separate leads where the instrument requires them.
• Mating receptacle selection support, including keying and contact-layout confirmation.

The CBTG2BG-SMSM02-D82B is a two-contact, straight cable plug that can be considered for portable DC motor armature test instruments — its 20.5 A rated current, push-pull locking mechanism, solder termination and cable collet provide useful advantages for equipment requiring detachable electrical test connections. This connector shows how Spring Technology serves motor test equipment, aligning a 20.5 A 2B cable plug with the customer’s armature tester requirements, and the company also provides professional customization services for both push-pull connectors and cable assemblies, offering tailored solutions to meet your specific technical requirements.
