The TE Connectivity 2-1123309-3 is a 4-position, dual-row shrouded header from the Dynamic D-5200 series, designed for board-to-cable/wire power interconnects in general-purpose and industrial equipment. It carries a 0.400" (10.16 mm) mating pitch and a 0.400" (10.16 mm) row spacing, giving it the creepage distance for the 630 V rating. Rated 30 A per circuit, each tab contact is sized for a main power rail, not a signal line. The right-angle through-hole orientation places the mating face parallel to the PCB, suiting board-edge cable exits in enclosed power supplies and industrial control panels.
Key Features and Characteristics
The mating contacts are gold-plated at 30.0 µin (0.76 µm) over a copper alloy base, with tin-plated solder tails. The 30 µin gold layer supports repeated mating cycles in field-service environments where the connector may be disconnected and reconnected during maintenance. The 4-wall shrouding protects the tab contacts from damage during handling and guides the mating receptacle into alignment. A detent lock provides audible and tactile feedback when fully mated, resisting vibration-induced separation. Board locks on the through-hole tails hold the header in place during wave soldering and add shear strength against cable strain. The housing is molded from a glass-filled thermoplastic polyester rated UL94 V-0, with an operating temperature range of -55°C to 105°C.
Applications and Environments
This header is suited for wire-to-board power distribution in industrial control cabinets, automation equipment, and general-purpose machinery where a 30 A per circuit rating is required. The IP20 ingress protection rating means it is intended for use inside an enclosure, not in washdown or outdoor environments. The wide temperature range and UL94 V-0 flammability rating make it acceptable for equipment that must meet safety agency requirements for internal wiring.
Lifecycle and Sourcing
The 2-1123309-3 carries an Obsolete lifecycle status from TE Connectivity. No official successor order code is listed. For a BOM line that requires this exact part, the procurement path is through the surplus and broker channel. This part is sourced and quoted to order against an RFQ — current availability and pricing are confirmed at quote time. Confirm the position count and mating half before committing the BOM.
