This header mates with MTA-156 receptacle housings that accept the corresponding crimp socket terminals. The 1-wall shroud guides the receptacle into alignment, and the friction lock engages the ramp on the receptacle housing. The 600VAC voltage rating covers most panel and industrial control circuits.","metaTitle":"TE Connectivity 644752-9 MTA-156 Header, 9 Pos, 3.96mm Pitch","metaDescription":"TE Connectivity AMP Connectors 644752-9 MTA-156 header, 9 positions, 3.96mm pitch, friction lock, tin contacts, UL94 V-0.
