High-reliability precision contacts engineered for industrial durability, modular connectivity, and harsh environmental conditions.
As the economic capital of the Haut-Sassandra region in Côte d'Ivoire, Daloa serves as a critical strategic node for agricultural processing, commercial transit, and regional infrastructure expansion. Over recent years, Daloa has experienced rapid modernization across cocoa and coffee processing facilities, logistics telemetry hubs, and distributed solar microgrid installations designed to electrification off-grid rural communities.
These demanding operating environments create unprecedented challenges for electrical engineering components. Standard soldered connections often succumb to ambient vibration, tropical thermal expansion, high humidity, and airborne particulates. The deployment of high-performance Double Head Type spring-loaded contacts (Pogo Pins) has emerged as the definitive solution for engineers and system integrators operating in Daloa. By offering double-ended compliance, zero-solder board-to-board bridging, and modular swap capabilities, double-head connectors ensure uninterrupted signal integrity and power transmission across critical equipment.
Double-head spring contacts feature mobile plungers at both ends, allowing dynamic mating between two opposing PCBs or contacts without thermal stress during assembly.
Understanding the mechanical physics, metallurgical composition, and contact dynamics of double-ended spring pins.
Plungers are precision-machined from Beryllium Copper (BeCu) or Japanese Brass alloys, ensuring high tensile strength, elasticity, and optimal conductivity. Outer barrels undergo precise Swiss CNC lathe turning to maintain tolerances within ±0.01mm.
Featuring specialized internal ball or bevel structures to maximize contact force and minimize contact resistance (<30mΩ). Supports continuous currents from 1A up to 30A for high-power distribution grids in microgrid setups.
Multi-layer surface treatment featuring 50μ"—100μ" Nickel underplating topped with 3μ"—30μ" real Gold plating. Provides exceptional corrosion resistance passing 48-hour to 96-hour Salt Fog testing, vital for West Africa’s damp climate.

| Plating Composition | Gold over Nickel (Au 3μ" over Ni 50μ") | Heavy Gold (Au 30μ" over Electroless Ni) | Prevents oxidation and electrochemical degradation from atmospheric moisture. |
Deploying targeted Double Head Pogo Pin technology to solve real-world industrial and commercial challenges.
In Daloa's expanding rural solar installations, modular battery packs require reliable inter-board communication and power transfer without rigid wiring harnesses that can loosen during transport over unpaved regional roads. Double-head spring pins act as vertical elastic interconnects between stackable BMS controller modules, offering high vibration resilience and effortless maintenance replacement.
Cocoa bean silos and agricultural storage units in Haut-Sassandra increasingly rely on environmental IoT telemetry (humidity, temperature, grain moisture sensors). Double head waterproof pogo pin assemblies enable quick-plug sensor probes that dock seamlessly onto sealed wireless transmitter units without exposing fragile circuitry to dust and moisture.
As a major logistical hub connecting central Cote d'Ivoire to coastal ports, heavy transport trucks in Daloa use ruggedized GPS and RFID fleet telemetry terminals. Double-head magnetic and spring contacts serve as dock-and-charge interfaces between vehicle dashboards and handheld logging terminals, standing up to continuous docking cycles.
Local technical workshops and regional electronic assembly facilities in Daloa utilize double-head pogo pins in ICT (In-Circuit Test) and FCT (Functional Circuit Test) fixtures. Double-ended contact pins allow rapid creation of custom matrix test beds for testing PCBs without requiring permanent soldering.

A Double Head Type Pogo Pin features spring-loaded plungers on both top and bottom ends. This design enables solderless, floating interconnections between two parallel circuit boards or contact plates. It absorbs spatial tolerances, eliminates the need for soldering on one end, and allows for rapid dismounting during field repairs in industrial applications across Daloa.
Our pogo pins feature advanced electroplating consisting of a heavy Nickel barrier coat (50μ"+) covered by real Gold plating (3μ" to 30μ"). This barrier prevents atmospheric moisture, tropical oxidation, and galvanic corrosion. Additionally, high-grade stainless steel springs maintain stable spring force even under prolonged temperatures up to 150°C.
