Features and Benefits


For ribbon-cable applications where PCB space is limited, design engineers require compact, high-density wire-to-board connectivity. Secure mating, cable retention and reliable electrical contacts are essential to ensure reliable connections in environments exposed to high vibration or shock. Manufacturers also need connector options that support various PCB assembly processes, circuit sizes and volume-production requirements.

In space-constrained designs, a 1.27mm-pitch insulation displacement technology (IDT) connector system can support dense power and signal routing. Locking, cable-strain relief and robust contact features help maintain secure electrical connections in demanding environments. To meet design, assembly and retention needs, features such as through-hole, surface-mount technology (SMT), high-temperature and positive-latch header configurations offer a flexible solution.

An insulation displacement contact (IDC)/IDT system, Picoflex Connectors from Molex offer a compact, robust solution with a 1.27mm pitch, a 6.40mm mated height and circuit sizes from 4 to 26 for high-density ribbon-cable connections. A strong one-piece housing, locking features, cable strain relief and multi-point contacts help support reliable performance in vibration and shock conditions. Multiple header options, including standard through-hole, SMT friction-lock, insulation resistance-compatible and positive-latch SMT versions, support design flexibility across PCB designs and manufacturing processes.


Provides increased mated connector retention force
SMT headers with positive retention latches increase connector retention force by 50% over standard connectors, avoiding disconnections that lead to electrical failures.

Enables high mating accuracy of the header and receptacle
The high-profile polarizing peg acts as a lead-in to aid in assembly, decreasing mis-mating risks.

Offers cost-effective plating solutions for diverse applications
Available in tin, palladium nickel and gold flash-plated contacts, these connectors deliver budget-sensitive options.

Meets safety standards to avoid fire hazards
Glow Wire-capable options support appliance designs requiring compliance with US and European IEC 60335-1 safety standards.

Improves electric and mechanical reliability for overall long-term performance
High-temperature housing materials make these connectors compatible with RoHS lead-free reflow soldering processes, withstanding elevated heat without damaging the connector.

Ensures accurate assembly
Optional PCB pegs polarize the header to the PCB, avoiding mis-mating.

Frequently Asked Questions


What are Picoflex Connectors?

Picoflex Connectors are compact, 1.27mm-pitch IDC/IDT ribbon-cable connector solutions designed for high-density power and signal applications. The system includes PCB headers, cable connectors and ribbon cable assemblies for space-constrained electronic designs.

When should I choose Picoflex Connectors instead of discrete wire-to-board connectors?

Picoflex Connectors are a strong option when a design has ribbon cable, requires high circuit density and must fit into limited PCB space. These connectors can simplify cable routing while providing secure electrical connections and strain relief.

Are Picoflex Connectors suitable for high-vibration and shock environments?

Yes, Picoflex Connectors incorporate locking features, cable strain relief and robust multi-point contacts that help maintain reliable electrical connections in applications exposed to vibration and shock.

What pitch and form factor does the Picoflex Connector system offer?

The Picoflex family uses a 1.27mm pitch and low-profile design, making it well-suited for applications where board space is limited and connector height must be minimized.

What PCB header options are available for Picoflex Connectors?

The Picoflex portfolio includes through-hole headers, SMT friction-lock headers, high-temperature infrared reflow-compatible headers and positive-latch SMT headers. These options help engineers select a solution that matches their PCB assembly process and retention requirements.

Do Picoflex Connectors support automated SMT assembly?

Yes, certain Picoflex headers are available in SMT configurations and can be supplied in tape-and-reel packaging for automated pick-and-place assembly processes.

What retention features help prevent accidental un-mating?

Picoflex Connectors offer friction-lock or positive-latch retention. The SMT latched header version provides enhanced retention compared to standard friction-lock versions, helping improve connector stability in demanding applications.

Picoflex Connectors are best suited for what kind of applications?

Picoflex Connectors are commonly used in appliances, automotive electronics, industrial automation equipment, medical devices, office equipment, displays, instrumentation and other products requiring compact ribbon-cable connectivity.

How do Picoflex Connectors help reduce assembly and field reliability issues?

The combination of a one-piece housing design, locking features, strain relief and robust contact geometry helps reduce cable movement, intermittent connections and potential assembly errors that can affect long-term reliability.

What are the key electrical and mechanical characteristics of Picoflex Connectors?

The Picoflex system offers up to 1.2A current per circuit, a 240V voltage rating and a 15 milliohm contact resistance. These connectors feature a 1.27mm pitch and a compact 6.40mm mated height, making them useful for densely populated electronic assemblies.
