Spring Loaded Pogo Pin Connector with Plastic Housing Sleeve for Smart Wearables, Medical Sensors, and Magnetic Charging Cable Docks

The 1-Pin Spring-Loaded Pogo Pin Connector with Plastic Housing Sleeve (PG3.5 x 9.4H) is a compact, high-precision single-pin interconnect component engineered for quick-disconnect power charging and signal transfer. Enclosed in a durable black plastic collar, this connector provides easy chassis panel alignment and structural isolation during device assembly.

Connection Interface & Mating Setup: Designed for direct soldering or press-fitting into device enclosures and cable assemblies, this Pogo Pin mates seamlessly with target gold pads, magnetic cable connectors, or custom PCB receiver boards. The integrated plastic sleeve serves as an insulator, preventing short circuits and offering mechanical strain relief under repeated compression.

Primary Application Scenarios: With its corrosion-resistant gold plating and compact 9.4mm height, this single pogo pin is extensively utilized in smartwatches, wearable health monitoring bands, wireless earbud magnetic charging pods, handheld medical diagnostic sensors, electronic vaporization devices, and custom magnetic charging cables.

Key Features

• Insulated Plastic Housing Sleeve: Black collar provides easy panel press-fit positioning, structural alignment, and electrical isolation.
