Frequently asked questions
What is the mating connector for 4-644615-2?
This header mates with a TE MTA-156 receptacle housing (e.g., 3-644615-2 or similar) and the corresponding crimp socket terminals. The friction lock on the header engages with the latch on the receptacle housing for a secure connection.
Does 4-644615-2 have a friction lock?
Yes, the fastening type is friction lock, which provides a positive latching mechanism to prevent accidental unmating under vibration or cable strain.
