Precision Terminal Cable Assembly | Custom AS150U 150A Anti-Spark Connector Wire Harness for Large Multi-Rotor UAV | RoHS Compliant Made in China

Precision Terminal Cable Assembly | Custom AS150U 150A Anti-Spark Connector Wire Harness for Large Multi-Rotor UAV | RoHS Compliant Made in China

Core Components & Accessories

• Male & Female Plastic Housings

Made of flame-retardant PA66 material, with 2 large current copper jacks + 2 central signal pins. Built-in mounting slots for fixed installation. Marked "5Ω" on shell to indicate built-in anti-spark pre-resistor.

• Gold-Plated Conductive Copper Posts

Thickened pure copper with full gold plating, low power loss & anti-oxidation. Male pins with buffer shrapnel, slotted female sleeves for tight contact, stable after thousands of plug-unplug cycles without overheating.

• Anti-Spark Resistance Post

5Ω pre-charging resistor built in female housing. It connects signal circuit first to pre-charge batteries during mating, avoids high-current arc to protect batteries and power equipment.

• Finished Wire Harness

8AWG silicone wires pre-crimped with male/female plugs. Red for positive pole, black for negative pole, extra thin signal wires. Bare stripped wire ends for direct soldering to batteries or ESC.

Key Features:​

✅ Built-in anti-spark design: Eliminates electric arc while plugging/unplugging, greatly reduces fire hazards

✅ Super large current capacity: 150A continuous output for high-power power systems

✅ Gold-plated low-resistance terminals: Excellent heat dissipation, low temperature rise under long-time operation

✅ Integrated signal detection pins: Compatible with BMS for battery voltage & temperature monitoring

✅ High-temperature silicone cable: 200°C heat resistance, anti-aging & flexible bending, suitable for outdoor equipment

✅ Reverse insertion prevention structure: Unique alignment of male & female ends to prevent reverse connection damage​

Important Notes:

1. Please confirm the connector model, pin sequence and wire gauge before installation to avoid wrong connection, short circuit or equipment damage.

2. Avoid using the wire harness in over-current, over-voltage or high-temperature exceeding the rated working range, to prevent wire heating and safety risks.

3. Keep the connector away from water, dust, oil and corrosive environments to ensure long-term stable conductivity and avoid poor contact.

4. Do not bend or squeeze the wire sharply for a long time; reasonable wiring protection can extend the service life of the harness.

5. For drone and flight model applications, check the locking buckle condition before flight to ensure firm connection and prevent mid-air disconnection.
