Features

  • Snap lock allows for easy insertion and extraction and prevents the accidental un-mating of the connector due to vibration or impact.
  • The plug diameter range from Ø12mm to Ø16mm, and satisfies the need for small-size, light-weight and high-density electronic components.
  • Equipped with internal metal parts and a shielding mechanism, the HR12 (20-contacts) and HR212 feature enhanced protection against EMI.

Cable Connecting Procedures Works Process Right-angle Plug Straight Plug 1 Use cables of fi nished dia. 4.8mm and nominal conductor cross section of 0.129mm (AWG#26) and under. (Inner dia. of solder pot of soldering terminal is Ø0.7mm.) 2 Insert bushing over cable as shown in Fig.1. Install hood over cable. Figure of straight type is omitted. Make cable end treatment to the dimensions shown in Fig.1. For shield cable, an example of cable end treatment is given below. (1) Firmly wrap the cable sheath end with copper tape 6mm wide, 16mm long and 85µm thick (overall thickness including adhesive). (2) Bundle up the shield cables, and tight twist. (Twist at least three turns over 6mm in length from the cable sheath tip) (3) Cut the shield cables at 6 -1mm from the cable sheath tip, and fold back as shown in Fig.1. (Soldering Type) Solder cables to mold block into which terminals are assembled. (Crimping Type) Use applicable tool (HR12-SC-TC or CM-105) to crimp connect cables to applicable crimping terminals, then insert crimped terminals into mold and fi x them to complete the mold block. 5 Assemble mold block having cables connected to location P shell A as shown in Fig.1. Carefully note that mold block and P shell A have directional polarization. 6 Assemble bundled shield cables so that they are positioned at the center (C section) of cable outlet of P shell A as shown in Fig.1. Install P shell B over P shell A as shown in Fig.2 and avoid catching of internal cables. Use the M2 self-tapping screws supplied (shape of screw head is phillip #0 for precision machinery) to secure from the direction of P shell B (2 places). Move bushing to the end face of P shell, and put P shell and bushing into the casing as shown in Fig.2. With groove of hood and protruding portion of P shell aligned, install hood over P shell as shown in Fig.3. Install casing over P shell as shown in Fig.4. 10 Now assembling is completed.

Silver reacts easily to exposure to sulfur gas so the below conditions may cause tarnishing. ɹɾDusty environments ɹɾArea with a high concentration area of gases such as sulfur dioxide gas, hydrogen sulfide gas, nitrogen dioxide gas and so on. Example; In close proximity to factory exhaust, automotive emissions, etc. ɹɾClose to heaters, or in other areas marked by extreme temperature differences or high humidity. ɹɾClose to rubber products includes rubber adhesives. The Electrical connection is not affected by tarnishing on a silver surface due to the wiping effect of the contact pins.
