From 60-Pin to 200-Pin: The Versatility of the LFH Connector

From 60-Pin to 200-Pin: The Versatility of the LFH Connector

In the world of advanced electronics, maximizing I/O capability in a minimal amount of space is a constant engineering challenge. This is where the Low-Force Helix, or LFH connector, provides an exceptional solution. Designed for high-density applications, this connector uses a unique helical contact design that allows for a high pin count in a compact form factor while maintaining a low insertion and extraction force, preventing damage to the PCB and the connector itself. Ideal for switch C-modules, data acquisition cards, and test and measurement equipment, the LFH connector is an elegant piece of engineering that enables complex, multi-signal connections without sacrificing board real estate or mechanical reliability.

I need to connect a device with an LFH connector to multiple D-SUB connectors.

This is a classic high-density breakout scenario, often found in test and communication systems. You have a central unit with a single, high-density LFH connector, and you need to connect it to several peripheral devices that use standard D-SUB connectors. The clean and reliable solution is a custom "fan-out" or "octopus" cable. KinKuo is an expert in building these complex harnesses. We can design and manufacture a cable that starts with a single LFH-160, for example, and breaks out into multiple DB-9, DB-15, or DB-25 connectors, with each branch labeled for easy identification and built to the exact length you need. This custom assembly eliminates a nest of clumsy adapters and provides a robust, single-piece solution for your complex interface requirements. Let KinKuo simplify your connectivity with a custom LFH connector to D-SUB breakout cable.

How do I find a supplier who can provide a reliable, tested LFH cable?

Reliability in a complex assembly like an LFH cable comes from the supplier's process and commitment to quality. The most critical thing to look for is a supplier who performs 100% electrical testing on every cable. A supplier who only does "batch" testing can easily ship a defective product. At KinKuo, our "perfect quality" promise is backed by our 100% testing guarantee. Every single LFH cable assembly is plugged into a test fixture that verifies the continuity of every pin. You should also look for a supplier with extensive experience with this specific connector, as it requires special handling. With 15 years of experience manufacturing the LFH connector and a steadfast commitment to 100% testing, KinKuo is the proven, reliable supplier you can trust to deliver a flawless cable, every time.

I need to connect a DAQ card with an LFH-60 connector to screw terminals. What cable do I need?

This is a very common requirement in the data acquisition world. You have a DAQ card with a high-density LFH-60 connector, and you need to connect it to real-world signals that are landed on a screw terminal block. You need a specific type of breakout cable. KinKuo specializes in manufacturing exactly this solution. We can build a custom cable that has the LFH-60 connector on one end and splits out into 60 individual, pre-stripped, and labeled wires on the other end, ready for you to land them on your terminal block. We can also terminate them into other connectors if needed. This provides a clean, reliable, and purpose-built solution that is far superior to trying to build a complex cable by hand. Let KinKuo provide the perfect breakout cable for your LFH-60 connector to simplify your test setup.

I need a quote for an LFH-200 connector assembly. What information do you need?

To provide you with a fast and accurate quote for a custom LFH-200 connector assembly, we need a few key pieces of information. First, we need the pinout: a wiring diagram or "from-to" list that specifies which pin on the LFH-200 connects to which pin on the other end(s) of the cable. Second, we need to know the desired connector(s) for the other end of the cable (e.g., screw terminals, D-SUBs, etc.). Third, tell us the overall length of the cable and the lengths of any individual breakout branches. Finally, let us know any special requirements for the cable itself (e.g., does it need to be shielded, high-flex, or have a specific color?) and your estimated order quantity. With this information, the team at KinKuo can provide you with a comprehensive and competitive quote for your custom LFH connector assembly.

Frequently Asked Question

Do you have any question?

A reliable manufacturer is critical when sourcing an LFH connector due to its complexity and fine pitch. A high-quality manufacturer ensures that the delicate helical contacts are formed with precision, that the insulator body is made from high-performance materials, and that the entire assembly is tested to guarantee that all pins are correctly terminated. This prevents frustrating intermittent connection issues that can be caused by a poorly made connector.

An LFH-60 connector is a specific variant of the Low-Force Helix family that features 60 pins. It is commonly used on professional data acquisition cards and some networking equipment. A breakout cable with an LFH-60 on one end is often used to provide multiple standard serial or digital I/O ports for the device.

 

Yes, absolutely. A key service from a specialist manufacturer like KinKuo is the ability to create a custom cable assembly built around an LFH connector. This can involve creating a breakout cable that transitions the high pin count of the LFH into multiple other connector types (like D-SUBs or discrete wires), using specific cable types for flexibility or shielding, and building it to your exact required length.

An LFH connector is distinct from VHDCI or SCSI connectors primarily in its contact design and purpose. While all can be used for data, the LFH is specifically optimized for high-density, low-force board-to-cable connections with a ground plane for signal integrity. VHDCI and SCSI are typically used for high-speed peripheral bus connections and have a different contact arrangement and mechanical design.

LFH connector is typically used in applications that require dense I/O, such as networking hardware like switches and routers (especially for C-modules), data acquisition (DAQ) devices, test and measurement equipment, and medical imaging systems. Its compact size makes it ideal for devices where multiple signal lines need to be brought in and out through a small panel space.

The main advantage of an LFH connector is its ability to provide a very high number of connections (often 60, 160, or even 200 pins) in a compact physical footprint. Its low-force helix contact design also means it requires significantly less force to mate and unmate compared to other high-pin-count connectors, which reduces mechanical stress on the board and ensures a long service life.
