CP-3.3 Wire-to-Wire Connector System

Molex CP-3.3 Wire-to-Wire Connector System leverages full keying and color-pairing features to enhance user safety while preventing moisture seepage in consumer electronics, white goods, industrial, and medical applications. The CP-3.3 Wire-to-Wire Connector System features single-row or dual-row configurations that is fully polarized with color-coded plug and receptacle housings to ensure fool-proof mating of the wired assembly. These connectors offer a 500V maximum rating in a -40°C to +105°C operating temperature range with maximum current ranges of 2.5A to 7.5A for single-row configurations and 2.0A to 7.0A for dual-row configurations.
