Low Profile “Swing-Lock” Board to Wire Connector for Power DF57 Series (Compliant with UL, C-UL standards) Swing-Lock Structure explanatory drawing Before mating Lock portion ■Features 4.65mm 1.Reinforced lock structure with swing lock After mating A swing-lock structure, featuring our own unique Mating HeightA : DF57H 1.4mm connection method, reinforces the lock structure of DF57AH 1.6mm Fig.1 the electric cable side, with a structure resistant to tough electric cable routing and disengagement of cables under load. Contact Structure In addition, the connection surface has a guide insertion to facilitate insertability (patented) 2. Header lock improves plug retention When connecting, the header connector secures the molded-lance. Play of molded lance is prevented for added strength. (patented) 3.H ighly reliable contact structure Despite the low-profile design, with a stacking height of 1.4mm, an effective mating length of 0.42mm is Fig.2 achieved. The structure features two-point contact terminal geometry with high contact reliability. Incorrect Positioning 4. Insert guide key prevents misalignment Insert Guide Key Positive Lock Insert guide key guides the crimp socket to the correct mating position and prevents misalignment, which improves mating operation and prevents possible connector breakage with incorrect mating. Insert guide key touches to 5. Solder wicking prevention the header prior to the positive lock, which guides The integral molding eliminates any gap between the the socket to the correct terminals and case to prevent solder wicking. mating position. 6.C ase disengagement prevention Starts mating after the socket is aligned to Reinforcing hardware (metal fittings) are integrated in the correct position the molding, which help prevent the case from disengaging with the terminals due to tough electric cable routing and load. 7. Cost effective Terminals and metal fittings are collectively integrated into the molding to reduce assembly cost. Insert Guide Key Structure Fig.3 In cases where the application will demand a high level of reliability, such as automotive, please contact a company representative for further information. 2018.6③ 1 Jun.1.2021 Copyright 2021 HIROSE ELECTRIC CO., LTD.

In individual applications the actual temperature may vary,depending on solder paste type, volume/ thickness and board size/thickness. Consult your solder paste and equipment manufacturer for specifi c recommendations. 2.Recommended manual soldering Manual soldering : 350ç ± 10ç for 3 seconds 3.R ecommended screen thickness and Thickness : 0.1mm open area ratio (Pattern area ratio) Open area ratio : 100% 4.Board warpage Maximum of 0.02mm at the connector center, with both ends of the connector as reference points. 5.Cleaning conditions Cleaning is not recommended. When cleaning, please evaluate as if can deteriorate the performance including mechanical operation and environmental resistance. ■ When inserting crimp-type (solderless) terminals to crimping (solderless) sockets, to maintain 6.Precautions reliable performance, please do not insert obliquely. ■ DO NOT mate/un-mate non-terminated plugs with non-mounted receptacles. This may lead to damage or deformation of the contacts. ■Removal of the holding electric cable may cause damage so please be careful. ■ DO NOT apply fl ux to the contact terminals when hand soldering the receptacle to the board. Wicking of the fl ux into the electrical contact areas may lead to connection failures. ■ Slight discoloration on the insulating materials will not affect form, fit or function of the connectors. ■ Please refer to the documents "DF57 Series Cable assembly Procedure ETAD-H0421", "Crimp condition" and "DF57-****SCF(A)(**) Crimp quality standards ATAD-H0404" for the cable assembly procedures. ■P lease refer to the "DF57H Series Mating/Unmating Operation Instruction Manual (ETAD-H0652)" for the connector operation. 7 Jun.1.2021 Copyright 2021 HIROSE ELECTRIC CO., LTD.
