Weidmüller SL-SMT 3.50/06/90RF 1.5SN BK BX Male Header Guide

The Weidmüller SL-SMT 3.50/06/90RF 1.5SN BK BX is a 6-pole male header created for compact PCB connection systems that require reliable mating performance, stable solder integration, and efficient manufacturing compatibility. As a member of the BL/SL 3.50 connector family, it supports board-level connectivity in industrial electronics where space, performance, and process consistency all matter.

Weidmüller SL-SMT 3.50/06/90RF Key Product Identity

This is a 6-pole male header with a 3.50 mm pitch, 90° plugging direction, and clip-on flange design. It uses a THT/THR solder connection and tinned contact finish. Its 1.5 mm solder pin length is specifically optimized for reflow soldering methods, supporting streamlined production in modern electronics manufacturing.

Weidmüller SL-SMT 3.50/06/90RF Technical Specifications

The Weidmüller SL-SMT 3.50/06/90RF 1.5SN BK BX is rated at 320 V / 15 A under IEC data and 300 V / 10 A under UL data. Its dimensions are 27.86 mm in width, 11.1 mm in depth, and 9 mm in height. The data sheet also specifies solder pin dimensions, eyelet hole data, and compliance information that support structured engineering and procurement workflows.

Why a 6-Pole Header Is Useful

Six-pole headers are frequently selected for grouped signals, compact subsystem interfaces, and low-footprint control modules. They provide more flexibility than smaller header formats while avoiding the larger footprint of higher pole-count versions. This makes the product highly practical in compact automation and electronics design.

Manufacturing Benefits

The reflow-optimized pin length and THR/THT concept support stable soldering outcomes and efficient production methods. That is especially important in medium- to high-volume manufacturing, where repeatability and PCB process compatibility play a direct role in product quality.

Typical Application Areas

Typical use cases include industrial electronics, compact control boards, communication devices, automation modules, measurement equipment, and space-conscious PCB interfaces that need six organized poles.
