1.27mm E-Type SMT Male Connector is a dual-row surface mount PCB connector designed for compact board-to-board signal applications where reliable electrical contact, stable PCB mounting, and high-density layout performance are required. Based on the drawing, this connector is an E-type SMT male connector with 1.27mm pitch, dual-row pin header structure, vertical 180° orientation, and H=6.7mm connector height.
The drawing identifies this series as DW-PH-2127730WVNP-XXTR-01, with variable total pin options from 10 pins to 100 pins. The part number structure indicates DW-PH pin header series, dual row, 1.27mm pitch, WV vertical 180° orientation, selectable total pins, selectable plating code, and TR tape reel packaging with plastic cap. This makes the connector suitable for automated SMT assembly and compact PCB designs requiring precise positioning.
This 1.27mm E-Type SMT Male Connector uses phosphor bronze contact and tail material. The contact plating is Sn and Au over Ni, while the tail plating is Sn over Ni, supporting dependable conductivity and soldering performance. The main body and cover material are LCP UL94V-0, suitable for high-temperature SMT processing. The drawing specifies a maximum processing temperature of 230°C for 30–60 seconds or 260°C for 10 seconds.
Electrical performance includes 1.0A rated current, 500V rated voltage, 25mΩ maximum contact resistance, 1000MΩ minimum insulation resistance, and an operating temperature range of -55°C to +125°C. With RoHS compliance, dual-row construction, surface mount termination, and multiple pin-count options, this connector is suitable for industrial control boards, communication modules, embedded systems, signal boards, and compact board-to-board PCB interconnection.
