Weidmüller 1000660001 BLF 5.08HC/04/90LH SN BK BX: Technical Insight into a 4-Pole Female Plug
The Weidmüller 1000660001 BLF 5.08HC/04/90LH SN BK BX is a practical board-to-wire connector for industrial electronics where easy handling and dependable conductor termination are essential. As a 4-pole female plug, it serves applications that need pluggable connectivity without giving up secure electrical performance or efficient wiring workflows.
Main Product Features
The product is built on a 5.08 mm pitch platform and includes 4 poles in a 90-degree format. It is described as a female plug with PUSH IN actuator technology, which is a notable advantage for both initial installation and later maintenance. This design supports a smoother connection process, especially in industrial settings where speed, consistency, and field serviceability all affect total system efficiency.
Connection Technology and Handling Benefits
The value of the Weidmüller BLF 5.08HC/04/90LH SN BK BX goes beyond its physical dimensions. PUSH IN with actuator technology is often preferred in professional control systems because it simplifies conductor insertion and removal. Technicians can work faster, while design teams benefit from a connection method that aligns with modern expectations for user-friendly industrial wiring.
For board-level product design, a 5.08 mm pitch also offers generous conductor accommodation and comfortable handling. That makes this connector well suited to interface boards, power control modules, relay circuits, and machine wiring points where a more substantial pitch is beneficial.
Electrical Ratings and Conductor Range
This connector is listed with IEC ratings of 400 V / 24 A and a wire range of 0.2 to 2.5 mm². Under UL, it is rated at 300 V / 18.5 A with a conductor range of AWG 26 to AWG 12. These values give the Weidmüller 1000660001 female plug solid versatility across signal and moderate power applications, especially in industrial and control-oriented equipment.
Typical Use Cases
The Weidmüller 1000660001 BLF 5.08HC/04/90LH SN BK BX is relevant in control panels, automation modules, monitoring equipment, machine interfaces, and custom electronics where removable field wiring is beneficial. The 4-pole layout is especially useful in compact power-and-signal combinations, auxiliary control wiring, and small board-mounted distribution points.
Search behavior around this item often includes Weidmüller 1000660001, Weidmüller BLF 5.08HC/04/90LH SN BK BX, and Weidmüller 4-pole female PCB plug. Those naming variations are natural across engineering, maintenance, and procurement functions.
