Weidmüller SL-SMT 3.50/08/90RF 1.5SN BK BX Male Header Guide
The Weidmüller SL-SMT 3.50/08/90RF 1.5SN BK BX is an 8-pole male header designed for board connection in compact industrial and electronic devices. Its high-temperature-resistant construction, 3.50 mm pitch, and reflow-optimized pin design make it especially attractive for manufacturers that need dependable solder integration and efficient assembly performance.
Weidmüller SL-SMT 3.50/08/90RF 1.5SN What This Header Offers
This product is a male PCB header with 8 poles, a 90° plugging direction, and a clip-on flange. It uses THT/THR solder connection and a 1.5 mm solder pin length optimized for reflow soldering methods. It is part of the OMNIMATE Signal BL/SL 3.50 family and is intended for use with compatible female plugs in the same system.
Weidmüller SL-SMT 3.50/08/90RF 1.5SN Technical Specifications
The official datasheet lists dimensions of 34.86 mm width, 11.1 mm depth, and 9 mm height. The header is rated at 320 V / 15 A under IEC product data and 300 V / 10 A under UL data. It also uses a tinned contact surface, black housing, and box packaging format.
Why an 8-Pole Header Is Strategically Useful
An 8-pole header can help consolidate several signals or compact power paths into one organized board-level interface. That reduces connector fragmentation and helps simplify both assembly and servicing. In industrial electronics, those advantages often translate into cleaner design and lower operational complexity.
Production Advantages
The product is specifically positioned for SMT-optimized processes while preserving the practical benefits of THT/THR soldering. This gives design and production teams a connector solution that aligns with modern PCB assembly strategies without compromising mechanical integrity.
Application Areas
Typical use cases include industrial control boards, automation electronics, interface modules, compact signal distribution systems, and machine communication subsystems that need an 8-pole board header.
