M12 A, D, X Coded SMT Receptacles

HARTING M12 A, D, and X Coded SMT Receptacles are a family of shielded, unshielded, SMD, and board-locking receptacles. These M12 receptacles are offered in 4-, 5-, and 8-pin models with coded configurations of A, D, or X. Other options include angled or straight, and male or female terminations. The HARTING receptacles feature a 250V voltage rating, 4A current rating, and gold-plated contacts.
