Push-Pull Connector for Teach Pendant Cables 2026: YH-C21046-2B-02 with CBTG2BG-SMSM08-D52B and CBTG3FN-SMSM08-D52B for USA Client

The YH-C21046-2B-02 is an 8-pin custom teach pendant cable assembly built with push-pull self-latching connectors — CBTG2BG-SMSM08-D52B and CBTG3FN-SMSM08-D52B — rated for over 5,000 mating cycles with gold-plated contacts, delivering reliable 24V power, E-Stop and RS485/CAN serial communication for six-axis robot arms. This push-pull connector for teach pendant cables keeps the operator interface linked to the robot controller through the heaviest production shifts. Every specification in this guide is backed by the in-house manufacturing and testing process of Spring Technology.

Pain point: Building a teach pendant cable that can survive daily use on a robot production line — constant plugging and unplugging, cable strain, and the safety-critical need for a dependable emergency stop circuit — while still carrying clean serial data between the control cabinet and the handheld pendant?

Core answer: Spring Technology designed and manufactured the YH-C21046-2B-02 custom teach pendant cable for a USA client. This 8-pin cable assembly links the control cabinet of an industrial six-axis robotic arm to the handheld teach pendant used by operators, using CBTG2BG-SMSM08-D52B and CBTG3FN-SMSM08-D52B push-pull connectors joined by a 3.7-meter, 24AWG cable. The custom teach pendant cable carries 24V power, the safety E-Stop circuit and serial communication (RS485 or CAN bus) in a single rugged assembly.

The YH-C21046-2B-02 is a complete cable assembly manufactured by Spring Technology from connector selection to final termination. Connections between a robot control cabinet and a handheld teach pendant typically rely on an 8-core cable measuring 3 to 5 meters in length; this assembly matches that convention at 3.7 meters with 24AWG conductors. The eight pins are allocated as follows: two for power (24V/GND), two for the safety emergency stop (E-Stop) circuit, and four for serial communication (e.g., RS485 or CAN bus).

• Latching Mechanism: Push-pull self-latching system (anti-vibration & shockproof)
• Recommended Hardware: Spring Technology Circular Connector
• Key Metric: Over 5,000 mating cycles on the 2B plug; >3,000 cycles with gold-plated contacts on the 3F plug

Every aspect of the YH-C21046-2B-02 was specified around the realities of teach pendant use. The design highlights below are why this custom teach pendant cable holds up on the factory floor:

• Dedicated 8-pin allocation — two pins for 24V/GND power, two for the safety E-Stop circuit, and four for serial communication (RS485 or CAN bus), keeping safety and data paths independent in one cable.
• Push-pull self-locking connectors — the CBTG2BG-SMSM08-D52B and CBTG3FN-SMSM08-D52B lock with a simple push and release with a pull on the sleeve, so operators can dock and undock the pendant quickly without threading.
• Vibration and shock resistance — rated for 15 g vibration (10~20000 Hz) on the 2B side and 147 m/s² with ≤1 µm instantaneous break on the 3F side, matching the harsh EMI and mechanical environment of servo-driven robot arms.
• Gold-plated contacts on the 3F connector — for stable low-resistance serial communication over RS485 or CAN bus.
• Wide temperature range — -45 °C to +125 °C (2B) and -55 °C to +145 °C (3F), covering cold workshops and warm control cabinets alike.
• Complete in-house manufacturing — Spring Technology builds the entire cable assembly, including termination, to the client’s specific requirements.

The YH-C21046-2B-02 draws on two mature push-pull connector families from Spring Technology: the 2B series for the pendant-side plug and the 103F series for the cabinet-side plug. Both are engineered for the high vibration resistance, mechanical durability and environmental sealing that industrial robotics demands, giving system builders a dependable push-pull interconnect platform.

• 2B series (TG plug, key G): 2 to 26 pin contacts, solder termination, chrome-plated brass shell, push-pull fastening, IP50 when mated. Available as straight plugs, plugs with bend relief, elbow plugs, fixed sockets (ZGG/ZCG/ZEG), free sockets (DHG) and more.
• 103F series (TG plug, key N): 2 to 16 pin contacts, solder termination, chrome-plated brass shell with gold-plated contacts, push-pull fastening, IP68 when mated. Available as straight plugs, plugs with bend relief, hermetic sockets (ZLN/ZGN), free sockets (DHN) and more.

• Complete custom cable assembly manufacturing — Spring Technology builds the full assembly, not just the connectors, according to specific requirements.
• Custom lengths (the 3–5 m range is typical for teach pendant applications), AWG selection, and pin allocation per the customer’s power and signal plan.
• Key orientation selection (G, N, A–F, L, R and more) to prevent mismating where several connectors share one machine.
• Footprint and interface engineering to match the standard push-pull connector layouts used across the industry.

Spring Technology is not only a connector manufacturer — it is a one-stop cable assembly connection solution provider. The YH-C21046-2B-02 is a direct example: the complete assembly was designed, terminated and tested in-house, without any intermediary suppliers, guaranteeing the same quality as the connectors themselves. Every connection requires its own dedicated cable, and Spring Technology supplies the complete system — including special materials, personalized layout and custom cable assembly — for industries ranging from robotics to medical, defense, aerospace and broadcast equipment.

• Automated processes for cable cutting, stripping and contact attaching.
• Ultrasound welding and extrusion capabilities using hot-melt and high-pressure/high-temperature techniques.
• A wide range of potting options for sealed systems, plus extruded cable crossovers and EMC-compatible assembly.
• Custom labeling tailored to each application.
• Ongoing inspections throughout production — including crimp force monitoring — and 100% final inspection of every assembly.

Spring Technology’s engineering team walks each customer through a structured four-step process:

• 1. Choose the connectors — Spring Technology’s own push-pull connectors, other standard connectors (Ethernet, USB, Audio/UHD Video), custom connectors or electronic solutions, or blunt-cut/pigtail terminations.
• 2. Select the cable type — extreme-environment cable (IP68 or hermetic sealing), medical-grade cable, rugged military cable, precision instrumentation cable, or fiber optic cable including copper-fiber hybrid.
• 3. Get the right bend relief — pre-molded bend reliefs for fast delivery, thermoplastic overmolds that permanently bond connector and cable, silicone overmolds for heat protection and maximum flexibility, or custom overmolds with multi-cable exits.
• 4. Confirm the wire connection — the engineer prepares a complete connection diagram, including all cable details, for the customer’s confirmation before production.

For teach pendant and industrial control applications that carry serial data, Spring Technology’s cable assembly team also supports high-speed connectivity — Ethernet up to 10 Gbit/s, USB 3.2 Gen 2 up to 10 Gbit/s, USB 2.0 up to 480 Mbit/s, and Audio/UHD Video — with low near-end crosstalk (NEXT), far-end crosstalk (FEXT), insertion loss and return loss, validated through design simulation and testing.

A teach pendant cable is the operator’s physical link to the robot: it must survive constant handling while carrying power, safety signals and control data without interruption. The YH-C21046-2B-02 is built for exactly this duty cycle on six-axis industrial robotic arms.

Operators use handheld teach pendants to jog the robot, record waypoints and monitor program execution. Because the pendant moves with the operator all day, its cable sees repeated flexing, tugging and docking — which is why the push-pull connectors on this teach pendant cable are rated for thousands of mating cycles.

The other end of the YH-C21046-2B-02 connects to the robot’s control cabinet, where servo drives and controllers generate significant electrical noise. The dedicated 24V power pins and shielded serial lines keep the E-Stop and RS485/CAN signals clean even next to high-power servo cabling.

Modern teach pendants exchange data with the controller over RS485 or CAN bus. The four serial pins in this custom teach pendant cable support either protocol, and the gold-plated contacts on the 3F connector side help maintain signal integrity over the full 3.7-meter run.

This custom teach pendant cable delivery for the USA client shows how Spring Technology turns standard push-pull connector platforms into a complete robot control interface — from the CBTG2BG-SMSM08-D52B pendant plug to the CBTG3FN-SMSM08-D52B cabinet plug, every detail of the YH-C21046-2B-02 was aligned with the customer's 24V power, E-Stop, and RS485/CAN communication requirements.
