The dual-row layout gives you 12 circuits in a narrower body than a single-row 12-position — useful when routing a harness through a tight cable gland or conduit. The black PBT insulation material handles -55°C to 85°C, which covers most control cabinet and light industrial environments without issue. The 'Contacts Not Included' note is not a footnote — it is the main procurement detail. You need the separate A3 series female crimp socket terminals (sold per reel or strip) to populate this housing. The difference is 12 positions versus 8 — four more circuits in the same body width. For a 12-circuit control interface, this is the direct fit.","metaTitle":"Hirose A3B-12D-2C Receptacle Housing, 12 Pos, 2.00mm","metaDescription":"Hirose A3B-12D-2C receptacle housing, 12 positions, 2.00mm pitch, dual row, crimp termination.
