Weidmüller BLF 5.08HC/02/90LR SN OR BX PCB Connector
The Weidmüller BLF 5.08HC/02/90LR SN OR BX, order number 1002280000, is a compact 2-pole female PCB connector designed for industrial electronics where a small number of circuits still require a high-quality pluggable interface. Although it has only two poles, it should not be underestimated. In many designs, a dedicated 2-position connector is exactly what is needed for power feed points, isolated functions, sensor connections, or auxiliary board interfaces.
What makes this version especially interesting is the 90LR variant structure. In the official family presentation, Weidmüller emphasizes not only the familiar PUSH IN advantages and durable contact behavior, but also self-locking and gentle unlocking. That makes the Weidmüller BLF 5.08HC/02/90LR SN OR BX PCB connector a strong option for applications where secure retention and controlled release are both important.
Technical Specifications and Core Identity
The Weidmüller 1002280000 is officially specified as a female PCB plug-in connector with 5.08 mm pitch, 2 poles, and a 90-degree format. It uses PUSH IN with actuator and supports a maximum clamping range of 3.31 mm². The published electrical data shows IEC 400 V / 24 A / 0.2–2.5 mm² and UL 300 V / 18.5 A / AWG 26–12. These are substantial ratings for a compact 2-pole connector and help explain why this product is attractive in industrial board design.
Because it is part of the BLF 5.08HC/90LR family, it adds a retention-focused behavior profile that many engineers actively look for when selecting a pluggable board connector for environments where movement, handling, or repeated service could be a factor.
Why a 2-Pole Connector Still Matters
A Weidmüller 2-pole PCB connector is often used for dedicated functions rather than general multi-signal grouping. That can include low-voltage supply input, isolated output connection, single-channel interface points, sensor power, or separate functional sections on a larger board. In these situations, a compact dedicated connector can be the cleanest and most logical design choice.
Using a dedicated 2-position connector also helps keep wiring clear. Instead of burying a simple function inside a larger multi-pole assembly, the designer can isolate it and make the intent of the connection immediately obvious to the installer.
The Practical Value of Self-Locking and Gentle Unlocking
This is where the Weidmüller BLF 5.08HC/02/90LR SN OR BX female plug stands out. Self-locking supports secure mating, while gentle unlocking helps reduce mechanical stress during disconnection. That is valuable in service scenarios and in applications where connectors may be handled repeatedly. It also contributes to user confidence, because a connector that feels secure in operation is easier to trust.
The right-angle construction further improves installation behavior by directing the conductor path horizontally, which can be very useful in compact housings or PCB assemblies with limited vertical space.
Selection Context for Engineers
The Weidmüller BLF 5.08HC/02/90LR SN OR BX 1002280000 is a logical fit when the design calls for a compact but robust pluggable PCB interface with secure retention characteristics. It is particularly appealing for OEM electronics, interface boards, control devices, and industrial equipment where a small number of terminations must still meet professional wiring standards.

Weidmüller BLF 5.08HC/02/90LR FAQ
What is the difference between the 90F and 90LR versions?
The 90LR family is presented by Weidmüller with added benefits such as self-locking and gentle unlocking. That makes it especially attractive when secure connector retention and controlled release are important design goals.
What is the Weidmüller BLF 5.08HC/02/90LR SN OR BX commonly used for?
It is commonly used for compact board-level connections such as dedicated power inputs, isolated outputs, sensor-related terminations, and other two-circuit industrial functions that still need a robust pluggable interface.
Is a 2-pole connector enough for industrial applications?
Yes, if the application only needs two circuits. In fact, choosing the exact pole count often improves wiring clarity and makes the board easier to understand and service.
Why is self-locking valuable in a PCB connector?
Self-locking helps keep the connector securely engaged, which can be useful in equipment exposed to handling, vibration, or routine maintenance. It adds confidence without making removal unnecessarily harsh.
Does this connector still offer strong electrical capability despite being small?
Yes. The official ratings show that it is designed for serious industrial board connection tasks within its specified limits. Its compact size does not mean it is a light-duty consumer part.
