Product Information
Full details
The Assmann WSW IDC Connector Low Profile Header (AWHC 40-0111-T) is designed for electronics professionals and hobbyists needing a reliable, solderless connection solution for 40-way circuitry. Its key benefit is the fast and secure wire termination via insulation displacement, eliminating the need for crimping or soldering. A potential consideration is its specific pitch, requiring compatible mating components.

FAQs
What does 'IDC' stand for?
IDC stands for Insulation Displacement Connector. It's a type of electrical connector that pierces the insulation of a wire to make contact, eliminating the need to strip the wire.
What is the pitch of this connector?
The pitch of this connector is 2.54mm, which is a standard spacing for many IDC connectors and ribbon cables.
Can I solder wires directly to this header?
No, this is an IDC connector designed specifically for insulation displacement termination with ribbon cables. Soldering directly is not the intended method of connection.
What is the maximum current rating?
The current rating for this connector is 1A.
What material are the contacts plated with?
The contacts are plated with a combination of gold and tin for optimal conductivity and corrosion resistance.
What is the insulation material?
The insulation material is PBT (Polybutylene Terephthalate) with a UL94V-0 flame retardancy rating.
How do I ensure a good connection with IDC?
Proper alignment of the ribbon cable with the connector and applying firm, even pressure during termination are crucial for a secure IDC connection.
Troubleshooting
No connection after IDC termination
Ensure the ribbon cable is correctly aligned and fully seated. Verify the cable conductors are intact and not damaged. Check that the correct type of IDC cable is used.
Intermittent connectivity
Re-seat the cable using the IDC termination process. Inspect the contacts for any signs of debris or damage. Ensure the mating connector is properly engaged.
Connector housing cracked during termination
Apply even, steady pressure during termination. If using a press tool, ensure it is the correct type for the connector and cable width. Avoid over-tightening or uneven force.
Pros and Cons
Pros
- Solderless termination significantly speeds up assembly.
- Low profile design saves valuable space in compact enclosures.
- Standard 2.54mm pitch ensures broad compatibility.
- IDC technology offers a secure and reliable connection.
- Durable PBT insulation meets safety standards.
Cons
- Requires specific IDC ribbon cables for termination.
- Not suitable for very high current applications.
- Limited to 40 ways, may require multiple connectors for larger harnesses.
- Requires precise alignment for successful IDC termination.
Setup, Compatibility & Care
Setup:
- Select a compatible 40-way ribbon cable with the correct conductor size for the 2.54mm pitch.
- Align the ribbon cable with the header, ensuring the keyway or polarity indicator matches.
- Use a dedicated IDC cable press tool or a firm, flat surface to firmly seat the cable into the connector's IDC slots. Apply even pressure across the connector width.
Compatibility:
- This header is designed to mate with standard 40-way IDC ribbon cable sockets or other compatible IDC connectors with a 2.54mm pitch.
- Ensure the wire gauge of your ribbon cable is appropriate for the IDC termination slots.
Care:
- Handle the connector by its housing to avoid damaging the contacts.
- Keep the connector and mating components clean and free from dust or debris.
- Avoid excessive force during mating or unmating to prevent physical damage.
