Mini-Fit Sigma Connectors & Pre-Crimped Leads

Molex Mini-Fit Sigma Connectors and Pre-Crimped Leads feature terminal position assurance (TPA) with a secondary locking feature to reduce assembly error. Connector terminals are fully sealed to prevent end-product failure. The Molex Mini-Fit Sigma components provide up to a maximum current of 11.5A and 600V_AC/DC maximum voltage. Pre-crimped leads offer female-to-female and female-to-pigtail configurations in 75mm to 450mm lengths, which are ideal for wire-to-wire use. Molex Mini-Fit Sigma applications include automotive, commercial vehicle, consumer, data/communications, home appliance, industrial automation, medical and telecommunications/networking.
