16 ML-TL-, Series TV, JT, LJT Universal Header ssembly for lex Print or PC oard MOUNTS TO LL ML-TL- The universal header assembly from mphenol provides for easy separation of the connector from the board. The header assembly is comprised of a short pin/socket contact. The tail end of the contact is soldered to the through hole of the flex or printed circuit board. The socket is embedded in the insulator, making electrical contact with the printed circuit tail of the connector. ETURES N ENETS: Circular and square header assemblies available Cost and time savings in the manufacturing process ssemblies can be vapor phase or wave soldered to flex/printed circuit board llows electrical testing when installed properly. Connector assemblies can be easily removed from and reattached to the header assembly. MOUNTNG PPLCTONS mphenol square universal headers are slotted to allow mounting to all series of ML-TL- or ML-TL connectors without special alterations. mphenol circular universal headers are designed to accommodate the rear flange of PC oard Mount shells, series ML-TL- connectors without special alterations. The header assembly can be attached to connectors with standard flange placement or directly to the circuit board. Connectors with dual flange mounting hardware can be provided to allow easy mounting to the panel or the header assembly. - orward flange would mount the connector to the panel - Rear flange would be used to mount to the header assembly. Various types of captivated or loose attaching screws can be utilized for unique applications. HEERS PROVE ESY SEPRTON O THE CONNECTOR ROM THE PC OR. MOUNTNG TO RECTNGULR RNC CONNECTORS Headers for RNC connector arrangements accommodate up to 150 pins Consult mphenol Canada, Ontario for RNC configurations. MTERLS ody is molded or machined from R-4. Electrical engagement areas of the header contact are plated with inches minimum of gold over inches minimum of nickel.

When using hot wire stripping, do not wipe melted insulation material on wire strands; with mechanical strippers do not cut or nick strands. 2. See Table 1 for proper finished outside wire dimensions. 3. Twist strands together to form a firm bundle. 4. nsert stripped wire into contact applying slight pressure until wire insulation butts against wire well. Check inspection hole to see that wire strands are visible. f there are strayed wire strands, entire wire end should be re-twisted. When wire is stripped and properly installed into contact, the next step is to crimp Contact the wire inside the contact by using the proper crimping tool. CRMPNG See table on preceding page for recommended M22520 series crimping tools, turret head or positioner selection settings according to contact size, part number and wire gauge size. 1. nsert stripped wire into contact crimp pot. Wire must be visible through inspection hole. 2. Using correct crimp tool and locator, cycle the tool once to be sure the indentors are open, insert contact and wire into locator. Squeeze tool handles firmly and completely to insure a proper crimp. The tool will not release unless the crimp indentors in the tool head have been fully actuated. 3. Release crimped contact and wire from tool. e certain the wire is visible through inspection hole in contact.

Connector holding tools are recommended while tightening back accessories. When using strain relief, center wires at bar clamp. Slide clamp grommet into position and tighten clamp bar screws. When tightening screws, pressure should be applied in the same direction that clamp is threaded to rear threads of connector. When not using clamp grommet, build up wire bundle with vinyl tape so clamp bar will maintain pressure on wires.
