Weidmüller 1000650000 SL-SMT 3.50/09/90RF 1.5SN BK BX: Technical Guide to a 9-Pole PCB Male Header
The Weidmüller 1000650000 SL-SMT 3.50/09/90RF 1.5SN BK BX is a compact PCB plug-in connector designed for engineers who need reliable board connection in control electronics, interface modules, compact automation devices, and industrial signal distribution. In practical terms, this Weidmüller 1000650000 male header belongs to the OMNIMATE Signal family and is built for applications where clean PCB integration, dependable mating, and stable electrical performance matter over the long term.
What the Product Type Tells You
The designation Weidmüller 1000650000 SL-SMT 3.50/09/90RF 1.5SN BK BX male header reveals most of the critical design details at a glance. It uses a 3.50 mm pitch, has 9 poles, and features a 90-degree orientation that supports right-angle board layouts. The connector is a male header with clip-on flange, which is particularly useful where mechanical retention and guided plug-in alignment are important. It also uses a THT/THR solder connection and a 1.5 mm solder pin length, making it relevant for designers planning for robust PCB anchoring and repeatable assembly quality.
Core Technical Characteristics
From a specification perspective, the Weidmüller SL-SMT 3.50/09/90RF 1.5SN BK BX is intended for dependable signal and low-power power distribution on printed circuit boards. The 3.50 mm pitch is a strong fit for space-conscious product development, especially where engineers need a balance between contact density and safe conductor separation. The black housing and tinned contact surface support standard industrial design practice, while the boxed packaging format is helpful for structured manufacturing and spare-part handling.
Another important point is compatibility in modular connection architecture. This kind of Weidmüller PCB male header is often selected when a design team wants a pluggable board interface rather than a permanently wired connection. That choice can simplify service, accelerate installation, and reduce wiring errors in the field. In products such as building automation nodes, monitoring devices, compact drives, and sensor interface boards, that advantage can be significant.
Electrical Performance and Design Relevance
For engineers comparing board connectors, voltage and current ratings are central. This model is specified with IEC values of 320 V and 15 A, while the UL values are 300 V and 10 A. Those figures make the Weidmüller 1000650000 connector suitable for a broad range of control and signal transmission tasks in industrial electronics. It is not simply about passing current; it is also about ensuring stable performance inside compact housings where heat, spacing, and long-term contact reliability all influence design success.
Typical Applications for the Weidmüller 1000650000
The Weidmüller 1000650000 SL-SMT 3.50/09/90RF 1.5SN BK BX is commonly relevant in PLC interface boards, I/O modules, HVAC controllers, alarm systems, instrumentation electronics, and custom embedded control assemblies. Because it is a 9-pole right-angle male header, it works well where PCB space is limited but structured multi-pole connectivity is still required. The clip-on flange also helps in designs where vibration resistance or secure mating guidance is desirable.
For engineers documenting a BOM, the product naming itself is also useful from a procurement and maintenance standpoint. Searching by Weidmüller 1000650000, Weidmüller SL-SMT 3.50/09/90RF 1.5SN BK BX, or Weidmüller 9-pole PCB male header can all support easier cross-team communication between purchasing, design, and service departments.
FAQ
What is the pole count of Weidmüller 1000650000?
The Weidmüller 1000650000 has 9 poles. That makes it a practical choice when a design needs multiple signal paths in a compact pluggable PCB connection.
Is Weidmüller 1000650000 a male or female connector?
It is a male header. More specifically, it is a PCB plug-in connector designed as a board connection component rather than a wire-side female plug.
What is the pitch of the Weidmüller SL-SMT 3.50/09/90RF 1.5SN BK BX?
The connector uses a 3.50 mm pitch. This pitch is widely appreciated in compact electronics because it supports a strong balance between density and usability.
What does 90RF mean in this Weidmüller connector?
In practical product interpretation, the designation indicates a 90-degree right-angle format with flange-related mechanical features, which is useful for side-entry board connection concepts.
Where is this connector typically used?
It is commonly used in control systems, industrial electronics, interface boards, compact automation devices, and other PCB-based assemblies that require a pluggable board connection.
Why would an engineer choose a pluggable male header like this?
A pluggable interface can improve maintenance access, reduce service time, simplify installation, and allow faster module replacement in the field.
