Molex Mini-Fit Sigma Connector System
Molex Mini-Fit Sigma Connectors offer a slim profile that mates with existing Mini-Fit headers, saving space without altering the bill of materials. These receptacles include TPA to ensure secure and stable connections, prevent terminal backout issues, and provide Glow Wire compatible options to meet European electrical standards. Mini-Fit Sigma connectors operate at temperatures up to +125°C and are available in board-to-board, wire-to-board, and wire-to-wire configurations.
Mini-Fit Sigma Sealed Power Connectors use traditional Mini-Fit TPA2 terminals and wire gauges while protecting against water, foam, and dust ingress. These devices deliver a pitch of 4.2mm, making these connectors suitable for various applications, including commercial vehicles, home appliances, consumer electronics, and industrial automation.

Personal protective equipment, or PPE, comes in a lot of forms: from simple gloves and facemasks to the full hazmat suit. It just depends on what you’re trying to keep out. For connectors, it’s a bit easier. Molex Mini-Fit Sigma Sealed Power Connectors protect against water, foam, and dust debris, keeping your power connections safe in whatever vehicle, appliance, or industrial machinery you put it on.
The connectors consist of a rubber cap that mounts to the back of the housing and is tested to IP54 requirements. The housings accept standard Mini-Fit TPA2 terminals, have supports for optional TPA inserts to keep terminals securely seated, and they have panel mount ears to keep the connector stable when mounted to a panel. Mini-Fit Sigma Sealed Power Connectors are keyed and polarized to mate with standard Mini-Fit 3.0 Power Connectors. They’re available with up to 14 circuits on a 4.2mm pitch and can carry up to 13A per circuit.
