Weidmüller BLF 5.08HC/16/90F SN BK BX Female PCB Connector Guide
The Weidmüller BLF 5.08HC/16/90F SN BK BX is a high-capacity female PCB connector built for applications that need more connection points without moving away from a service-friendly pluggable interface. With 16 poles, a 5.08 mm pitch, and a 90° conductor outlet, it supports organized wiring in industrial electronics, automation modules, and machine interface boards. Because it uses PUSH IN with actuator technology, it also aligns well with current expectations around efficient installation and dependable long-term use.
Product Positioning in the Weidmüller Range
This Weidmüller BLF 5.08HC/16/90F SN BK BX female PCB connector is part of the OMNIMATE Signal BL/SL 5.08 product family. It is intended for field connection and offers a single-row, 16-position design. That makes it especially useful where several circuits need to be grouped inside one pluggable connector rather than distributed across multiple smaller connection points. In real system architecture, that can improve cable management, simplify replacement, and support cleaner board layouts.
Main Technical Specifications
The connector is rated according to IEC product data at 400 V, 24 A, and 0.2 to 2.5 mm². Under UL data, it is rated 300 V, 18.5 A, and AWG 26 to AWG 12. The maximum clamping range is 3.31 mm². Its dimensions are 26.2 mm depth, 20.6 mm height, and 91.08 mm width. It provides IP20 protection when plugged, IP10 when unplugged, supports 25 plugging cycles, and uses a 10 mm stripping length. In addition, the connector is designed to be coded, which is useful in assemblies where connector differentiation matters operationally.
Why a 16-Pole Female Plug Is Useful
When a board must accommodate a larger number of field connections, a 16-pole connector can reduce fragmentation across the design. Instead of splitting circuits into several smaller plugs, engineers can group them in one consistent connection format. The Weidmüller BLF 5.08HC/16/90F SN BK BX is therefore a sensible choice for controller interfaces, distributed I/O assemblies, building automation units, and industrial electronic devices where space, organization, and serviceability all need to be balanced.
The Value of PUSH IN with Actuator
The PUSH IN concept helps this connector stand out. In production and maintenance workflows, speed matters, but so does repeatability. A connector that enables quick conductor insertion while still allowing deliberate release and controlled handling can contribute to better assembly efficiency and lower service effort. In this respect, the Weidmüller BLF 5.08HC/16/90F SN BK BX supports modern industrial wiring expectations without moving away from familiar PCB pluggable connector architecture.
Materials, Compliance, and Durability
The housing uses PBT insulating material, with black as the main body color and orange for the operational elements. The contact material is a copper alloy with a tinned finish, and the product carries a UL 94 V-0 flammability rating. It is compliant without RoHS exemption and reports no SVHC above 0.1 wt%. The datasheet also lists an operating temperature range from -50 °C to 100 °C. Those details matter because connector selection is rarely only about voltage and current; environmental resilience and compliance readiness also influence purchasing and engineering decisions.
Where This Weidmüller Connector Performs Well
The Weidmüller BLF 5.08HC/16/90F SN BK BX female PCB connector is a strong fit for industrial electronics, machine controls, panel interface boards, modular power and signal assemblies, and systems that require many organized terminations in a serviceable format. Searches for Weidmüller BLF 5.08HC/16/90F SN BK BX female PCB connector, 16 pole PCB terminal block connector, or Weidmüller pluggable terminal block 5.08 mm often point to exactly these use cases.

FAQ
What is the main advantage of the Weidmüller BLF 5.08HC/16/90F SN BK BX?
Its main advantage is the combination of higher pole count, pluggable serviceability, and PUSH IN connection technology. That makes it well suited to applications that need more terminations in a single organized connector.
Is this connector intended for industrial PCBs?
Yes. It is specifically intended as a field connection interface on printed circuit boards and is aligned with industrial control and electronics applications.
What wire range does it support?
It supports 0.2 to 2.5 mm² under IEC data and AWG 26 to AWG 12 under UL data, covering a broad range of commonly used industrial conductors.
Can it help with maintenance efficiency?
Yes. Because it is a pluggable female connector, devices can often be disconnected and reconnected more efficiently during servicing, replacement, or testing.
What makes the 5.08 mm pitch relevant?
The 5.08 mm pitch is widely used in industrial board connection systems because it provides a practical balance between conductor capacity, spacing, and ease of handling.
