Product details

0.100" pitch, 3-position MTA-100 header with friction lock

The 3-641126-3: This is a TE Connectivity MTA-100 series header, 3 positions on 0.100" (2.54mm) pitch, vertical through-hole, shrouded on one wall with a friction lock. It mates with MTA-100 IDC receptacles or crimp housings — the lock prevents accidental unmate from vibration or cable pull. Gold on the interface means reliable low-resistance connections across repeated mating cycles — a common spec for field-serviceable or test equipment.

Through-hole solder termination, UL94 V-0 housing

Frequently asked questions

Is 3-641126-3 shrouded?

Yes, it is shrouded on one wall (Shrouded - 1 Wall). The single wall provides keying and partial polarization to prevent mis-mating with the receptacle.
