One key feature of M5 connector assembly and small M6 connector design is Thermoplastic Polyurethane (TPU) over-molding. This material enhances the durability of the connectors by providing superior resistance to environmental factors such as moisture, dust, and temperature changes. TPU over-molding forms a protective barrier that ensures long-lasting operation, even in harsh conditions. For industries that rely on consistent performance, such as medical monitoring or solar energy systems, TPU over-molding is vital. Its ability to shield the connector from oil stains and maintain the integrity of electronic connections is a game-changer for reliability.
