The friction lock mates with the corresponding MTA-156 receptacle housing, providing a positive hold against vibration in industrial control panels and general-purpose equipment. The 644752-2 mates with any MTA-156 receptacle housing that accepts a 0.156\" pitch male pin header — typically the 640250 series or 640251 series from TE. Mounting is through-hole with solder termination; the 0.175\" (4.45mm) post length suits standard 1.6mm PCBs.","metaTitle":"644752-2 TE MTA-156 Header, 2 Pos, 3.96mm Pitch","metaDescription":"TE Connectivity AMP MTA-156 header, 2 positions, 0.156\" pitch, tin contacts, friction lock, UL94 V-0, -55~105°C.
