Molex Mini-Fit Sigma Sealed Connector, Custom Wire Harness Manufacturer

Molex Mini-Fit Sigma Sealed Connector

The Molex Mini-Fit Sigma Sealed Power Connectors are robust, wire-to-wire connectors specifically designed to deliver secure, high-performance connections in challenging environments. Utilizing Mini-Fit TPA2 terminals, these connectors support a variety of wire gauges while providing reliable resistance to water, foam, and dust, which enhances their durability and performance in harsh conditions. Featuring a 4.2mm pitch, these connectors are ideal for demanding applications, such as commercial vehicles, consumer and industrial automation, and household appliances, where sealed protection is essential to prevent ingress of moisture and debris. The Mini-Fit Sigma connectors are engineered to withstand wide temperature ranges, operating effectively from -40°C to +105°C, which makes them suitable for diverse climates and intense conditions. With a high current rating of up to 13A and a maximum voltage capacity of 600V, these connectors provide robust electrical performance, meeting the needs of high-power applications without compromising safety or reliability. The Molex Mini-Fit Sigma series thus offers a comprehensive solution for environments requiring secure, stable, and weather-resistant connectivity.
