Product details

24-position single-row header for MTA-100 harnesses

The single-wall shroud guides the receptacle during mating and protects the pins from accidental bending. No secondary latch or TPA is present; the lock relies on the interference fit between the header and receptacle.

Through-hole solder termination, tin contacts

Termination is through-hole solder, with the contact post measuring 0.140" (3.56mm) long — sufficient for a standard 1.6mm PCB. Both the mating and post finishes are tin. Tin contacts are rated for fewer mating cycles than gold — typically 25–50 cycles — but carry adequate current for signal and low-power applications.

Frequently asked questions

What is the closest pin-compatible alternative to the 2-640456-4 in the MTA-100 series?

For a 24-position header with a friction lock, the 2-640456-4 is the standard offering; no identical pin-compatible alternate is listed. Confirm the circuit count and lock style before substituting.
