What Is Battery Connector 005904080071 Used For?

Battery Connector 005904080071 is a specialized interface component designed for secure electrical connections in battery-powered systems. It typically features 1.25mm–2.0mm pitch configurations with gold-plated contacts, optimized for low-voltage, high-reliability applications in devices like IoT sensors, medical equipment, and portable electronics. Its compact design supports 3–5A continuous current flow with IP67-rated sealing in select variants, preventing oxidation in humid environments. Pro Tip: Always verify pin alignment when mating these connectors—offset insertions can permanently deform contact springs, increasing resistance by 15–30%.

Beyond its robust shell, the 005904080071 employs twin-leaf spring contacts that maintain ≤10mΩ resistance even after thermal cycling (-40°C to +85°C). For instance, drone manufacturers pair this connector with 7.4V LiPo packs due to its vibration-resistant design. Warning: Avoid using silicone-based lubricants on contacts—they attract dust particles that degrade signal integrity over time.

Which devices commonly use 005904080071 connectors?

Prevalent in wearable medical monitors and industrial handheld scanners, this connector supports quick battery swaps without tools. Its 8mm profile fits space-constrained designs like:

Tablet-based inventory systems leverage this connector for hot-swappable battery modules, enabling 24/7 operation. Pro Tip: Implement a polarized connector variant (005904080071-P) to prevent reverse polarity incidents during field maintenance.

How does 005904080071 compare to JST PH series?

While both serve compact electronics, the 005904080071 offers 25% higher current capacity at 3A vs. JST PH’s 2A limit. Critical differences include:

For example, robotics designers prefer 005904080071 for motorized joints requiring sudden current surges up to 5A. However, JST PH remains cost-effective for low-drain applications like Bluetooth peripherals. Always cross-reference termination types—005904080071 requires specialized crimp tools for its 0.64mm contact tabs.

What safety certifications apply to this connector?

The 005904080071 meets UL 1977 and IEC 60664-1 standards for creepage/clearance distances, essential for medical and automotive subsystems. Compliance highlights:

Consider this analogy: The connector’s 3.2mm air gap between contacts acts like a circuit breaker’s gap, preventing arc faults below 24VDC. Warning: Non-compliant counterfeits often skip dielectric testing—always request certification docs for mission-critical deployments.

Can 005904080071 handle wireless charging systems?

While compatible with 5W Qi charging pads, its brass alloy contacts show 12% efficiency loss at 100kHz frequencies compared to beryllium copper alternatives. Implementation guidelines:

In earbud cases, engineers pair shielded 005904080071 variants with ferrite beads to suppress EMI above 30MHz. Pro Tip: For >10W wireless systems, upgrade to the 005904080071-HF version with frequency-optimized contact geometry.
