Molex 3mm Male Crimping Pins – 100 pcs

Description

The Molex Micro-Fit 3.0 Male Crimping Pins are high-reliability, compact, and robust male electrical contacts designed for use in Molex’s Micro-Fit 3.0 interconnect system. These pins are engineered to terminate stranded wire and insert into Micro-Fit male connector housings for both wire-to-wire and wire-to-board applications. With a 3.00 mm pitch, they are optimized for applications requiring space efficiency without compromising power handling or signal integrity.

Constructed from high-conductivity phosphor bronze, these crimp pins provide both mechanical strength and stable electrical performance. The contact area is typically plated with tin for cost-effective corrosion protection, although gold-plated variants are also available for environments requiring superior oxidation resistance and extended mating cycles.

Molex Micro-Fit 3.0 male terminals are designed to accommodate wire gauges ranging from 30 AWG to 20 AWG, depending on the specific part number. The terminals are crimped to wire using manual or automated crimp tools and inserted into male connector housings where they lock in place via integrated retention tangs, ensuring a firm mechanical fit and preventing backing out during vibration or movement.

The Micro-Fit 3.0 system is known for its high current-carrying capability of up to 8.5 amps per contact—a significant amount for connectors of this size. This makes the male pins ideal for use in power-dense applications such as industrial control systems, medical devices, telecommunications equipment, automotive electronics, and consumer products like 3D printers or power supplies. The contacts are rated for operation in environments from -40°C to +105°C (up to +125°C for some gold-plated types), offering excellent thermal resilience.

These terminals support multiple contact points and optional Reduced Mating Force (RMF) designs that reduce friction during connector engagement, increasing usability and reducing wear in frequent mating cycles. When properly crimped and installed, Molex Micro-Fit male pins offer low contact resistance (<10 mΩ) and long-term durability even under demanding operating conditions.
