CBTL4FN Push-Pull Connector for Drilling Telemetry 2026: Custom Cables YH-C21046-104F-T27A and YH-C21046-104F-T27B with Brass Chrome Plugs for LWD/MWD Umbilicals for Saudi Arabian Customers

The CBTL4FN-SMSM19-D920 is an CBTL4FN push-pull connector for drilling telemetry — a rugged brass chrome 19-pin plug built into the custom YH-C21046-104F-T27A and T27B cables for LWD/MWD logging umbilicals, keeping 19 channels of deep-earth telemetry continuous through crude oil, mud, acidic H2S gas and drill string vibration, with gold-plated contacts. Every specification in this guide is backed by the downhole telemetry interconnect engineering of Spring Technology.

Pain point: Wiring the umbilical rigs of Logging-While-Drilling and Measurement-While-Drilling tools — where drilling fields are flooded with crude oil, mud and acidic hydrogen sulfide gas, and drill string vibration threatens the continuity of deep-earth telemetry?

Core answer: For Saudi Arabian customers, Spring Technology supplied two customized cable assemblies built with an CBTL4FN push-pull connector for drilling telemetry: YH-C21046-104F-T27A and YH-C21046-104F-T27B. Each custom cable consists of an CBTL4FN-SMSM19-D920 plug, a cable and an CBTL4FN-SFSM19-D920 plug, built into the umbilical wiring rigs for Logging-While-Drilling (LWD) and Measurement-While-Drilling (MWD) logging tools at the surface or well-deck level. The rugged brass chrome shell and push-pull latching mechanism ensure the 19 channels of deep-earth telemetry remain perfectly continuous, resisting heavy physical shocks from drill string vibration.

This drilling telemetry cable is a custom assembly built on the TLN.104F plug platform with standard brass chrome shells. The 19-pin layout on both ends carries the telemetry channels of LWD/MWD logging tools.

• Latching Mechanism: Rugged push-pull self-latching system (anti-vibration & shockproof)
• Recommended Hardware: Spring Technology Circular Connector
• Key Metric: Brass chrome shell; 19 telemetry channels; crude oil, mud and H2S resistance

Oilfield umbilicals must hold telemetry continuity through the most punishing environment in industrial electronics. The design highlights below are why this CBTL4FN push-pull connector for drilling telemetry is specified for LWD/MWD rigs:

• Rugged brass chrome shell — holds up in drilling fields flooded with crude oil, mud and acidic hydrogen sulfide (H2S) gas.
• 19 channels of telemetry — deep-earth telemetry stays perfectly continuous across both custom cable assemblies.
• Rugged push-pull latching — the self-latching mechanism resists heavy physical shocks from drill string vibration.
• Matched plug-and-socket ends — each cable carries the CBTL4FN-SMSM19-D920 plug and CBTL4FN-SFSM19-D920 socket for umbilical wiring.
• Surface and well-deck ready — built into LWD/MWD logging tool umbilical rigs at surface or well-deck level.
• Gold-plated contacts — stable 19-channel signal paths for continuous telemetry.

The 4F (104F) shell is part of Spring Technology’s waterproof connector families, with standard brass chrome finishes for oilfield service. The CBTL4FN platform in this order scales across downhole and surface logging equipment.

• Plugs: TLN.104F-based straight plugs (this order) in standard brass chrome versions.
• Sockets: matching socket versions (this order) for umbilical and panel wiring.
• Pin counts: 2 to 19 pins on the 4F (104F) shell.
• Cable assemblies: custom lengths and part numbers via the Custom Cable Assembly service.

• Custom cable part numbers (such as YH-C21046-104F-T27A / T27B) with matched connector pairs.
• Finish and material options for corrosive drilling environments.
• Pin allocation tuning for telemetry and power channels.
• Vibration and sealing verification for drill string conditions.

From the well-deck umbilical to the logging tool, drilling telemetry depends on one continuous link. This CBTL4FN push-pull connector for drilling telemetry delivers it.

The custom cables are built into the umbilical wiring rigs for Logging-While-Drilling and Measurement-While-Drilling logging tools at the surface or well-deck level.

19 channels of deep-earth telemetry remain perfectly continuous, resisting heavy physical shocks from drill string vibration.

Flooded with crude oil, mud and acidic hydrogen sulfide gas, the rugged brass chrome shells keep the telemetry link intact through the operation.

This custom cable delivery for Saudi Arabian customers shows how Spring Technology serves downhole exploration — from the brass chrome CBTL4FN-SMSM19-D920 and CBTL4FN-SFSM19-D920 ends to the YH-C21046-104F-T27A and T27B assemblies, every detail was aligned with the customer’s LWD/MWD umbilical requirements. Spring Technology’s Custom Cable Assembly service combines automatic wire cutting, crimping, ultrasonic welding, potting and EMC assembly to deliver ready-to-use interconnect solutions.
