MR60 3.5mm Gold Bullet Connector for Motor-to-ESC Wiring

MR60 Male Connector 3.5mm Bullet Connector for Motor and ESC Connection

The housing of the MR60 connector prevents the wire from being exposed, which also protects people from the power. It is made from fireproof material and the listing says it passes UL, CE and RoHS certifications.

With a high current endurance performance, it can be used many times, reaching 1000 times. It is often used in remote control aircraft and other RC models, for example on large RC LiPo batteries (MR60 female), RC ESCs (MR60 male) and RC chargers.

This listing is for the MR60 male plug with 3.5mm gold bullets, suitable for connecting ESCs and motors.

Key features

• Made for ESC and motors: suitable for connecting ESCs and motors.

• Protective sleeve: the housing stops the wire from being exposed.

• Assistive weld foot: makes soldering more stable.

• Fireproof material: UL, CE and RoHS certified per the listing.

• High endurance: reusable up to 1000 times.

How a bullet connector plug works

A power connector is the link between your battery and everything that draws current from it. It has to hold securely, carry the current without heating up and, ideally, only fit together one way so that reverse polarity is impossible. The metal contacts are usually gold plated to resist corrosion, and the housing holds the two contacts apart and keeps them aligned.

Solder connectors with a clean, hot joint and enough solder to fill the cup, then slide heat-shrink over the joint so no bare metal is exposed. A cold or under-heated joint has high resistance and gets hot under load, which is the most common cause of connector failure. Always check polarity before you plug in a battery for the first time.

Choose connectors by the current they will actually carry, not just by how they look. A connector that is too small runs hot and can melt its housing, while a connector that is rated well above your load stays cool and lasts longer. Inspect connectors periodically, and replace any that show discolouration, loose contacts or cracked housings.
