2mm Pitch, Positive lock, Wire-to-Board Connector (UL, C-UL Listed) DF51K Series Secure mating with clear tactile click Insertion force to lock Matches the peak Features Insertion force to contact 1. P ositive lock provides clear tactile click and secures reliable connection Matching peak insertion forces provides The locking mechanism delivers a clear tactile click, which a clear click sound and tactile click ( ) prevents incomplete mating. Fig.1 Fig.1 2. Wide variation Straight and right angle types are available in single row and double row contact arrangements for flexible board design. Gold and Tin plating options support various application needs. 3. Easy Lock Release The width of the center lock lever increases as the pin count increases for easy extraction. Additionally, the center lock design does not need side-to-side spacing to un-mate the connector, which enables high density Center lock width gets wider as the pin count increases mounting. (Fig.2) for easy operation. 4. Prevents incorrect mating Extra spacing not Visually and mechanically polarized design prevents reverse required mating and incorrect mating between different number of positions. (Fig.3) 5. Suitable for potting High workability and high density mounting Capable of being potted up to 3mm. (Fig.3) due to center lock design Fig.2 6. Uses the same crimp tools as DF11 Series Wide applicable cable range : 22 to 30 AWG. (However, the crimp contact of DF51K and DF11 are not compatible with each other.) Secure Center Lock Design 7. UL, C-UL certified Guide Key Prevents Incorrect Mating Applications Resin Sealing 3mm Max. Office equipment, Industrial machinery, Industrial robots, Amusement equipment, Medical equipment.
