HA screw-terminal inserts provide slim rectangular connections with 10, 16 or 32 contacts plus protective earth. The 32-contact arrangement combines two 16-contact blocks in an H32A enclosure. Select matching male and female inserts, keeping both contact-numbering ranges when assembling a 32-contact connector.

Drawings and assembly
Male and female outline drawings include contact numbering, side profiles and panel cutouts. The drawings marked HA-016-M or HA-016-F with positions 17-32 describe the second block of the corresponding HA-032 assembly. Use them together with the positions 1-16 drawings; a single-block outline is not the complete 32-contact assembly envelope.
Choose the hood, housing, mounting style and cable entry for the indicated A-size enclosure. The completed enclosure determines connector sealing and installation clearances.
