They are available in continuous strip form up to a maximum length of 6 inches (152.40mm), accommodating from 1 to 60 rear insertion, front release, crimp snap-in size 22 CENTIPINTM/ CENTISOCKETTM contacts. These contacts utilize a proven positive contact alignment design, giving additional contact strength and positive contact alignment during mating. These connectors can be ordered in kit or bulk form. The kit comprises all the parts necessary to assemble one complete 6-inch (152.40) strip connector with 60 contacts on .100 (2.54) centers or a 4-inch (101.60mm) strip with 53 contacts on .075 (1.91) centers. If more then one connector is required, the parts can be ordered in bulk and assembled as desired. Components and Accessories The CENTI-LOC strip connector can be ordered in kit or bulk form. The kit includes matin g insulators with a full compliment of contacts and two guide posts. If more than one connector is required, the parts can be ordered in bulk and assembled as desired.

There are a few helpful suggestions that will assure complete satisfaction when followed: 1. The following instructions should be followed. 2. The proper crimp tool and locator (if required) must be used. These tools have been designed for use with this product. Substitutions of crimping equipment may result in connector failure at the assembly operation. 3. After crimping a contact to a lead it is of vital importance that the proper tool be used to assure seating the contact in the insulator in the proper position. Any substitution of insertion tools may result in over or under insertion of the contact which may damage the retention system of the insulator. 4. The female (socket) side of the connector has been designed with a controlled float to allow for ease of mating. To avoid reducing this float or causing a splaying of the contacts, any unnecessary strain caused by clamping the leads too close to the rear of the connector should be avoided. Use of recommended tooling together with proper assembly techniques will pay dividends in reliability and reduced costs. 2D Assembly Instructions CONTACT CRIMPING WIRE STRIPPING .100 (2.54) Cut the wires to length required and strip .100" of insulation from the end to be crimped. Check for cut or broken wires and frayed insulation. Using the proper crimp tool and locator, insert the contact into the locator. Insert the stripped end of the wire into the contact crimp pot, and crimp the contact to the wire. Squeeze the handles firmly to insure a proper crimp (tool will not release if crimping is incomplete). NOTE: Contact stop must be changed in tool locator when crimping pin and socket contacts. CONTACT INSERTION CONTACT EXTRACTION 1. For contact extraction, remove the insertion tool tip and replace it with the proper extraction tool tip. (The socket tip will fit into the socket, and the pin tip will slide over the pin bundle). Insert the tool tip into the contact cavity: (the pin tip will butt up against the shoulder of the pin contact, and the socket tip will bottom out in the socket contact.) Dimensions shown in inches (mm) Specifications and dimensions subject to change www.ittcannon.com D-87 2. Apply a firm, steady pressure until the contact is released from the internal shoulder in the insulator. The shoulder of the tool tip bottom against the insulator face to prevent damage to the internal shoulder. Remove the tool tip and pull the contact from the rear of the connector. Repeat for the balance of contacts to be removed. D Microminiature 1. Place the proper insertion tip in the insertion/-extraction handle and put the tip over the wire as shown. The tool tip will butt up against the crimp pot. Connector must be firmly supported during both insertion and extraction operations. 2. Using a firm, steady pressure, push the contact into the cavity until the resilient internal shoulder in the insulator snaps into the locking groove in the contact. The shoulder of the tool tip bottoms against the rear of the insulator, preventing over-insertion. Repeat for balance of contacts. ca_D1-D102:Layout 1 2/10/11 11:52 AM Page 88 The Centi Line - .075" Contact Spacing 2D/CTA CTA Assembly Instructions INSERTION 1. Place the connector into the slot in the assembly block with the arrows on the insulator pointing downward. The connector will bottom against the internal shoulder in the groove in the assembly block. Start contact insertion by placing the crimped contact in the cavity by hard. 2. Position the insertion tool tip on the rear of contact as shown. The insulation must be pulled back from the crimp pot approximately 1/32" to allow the tool tip to butt against the contact crimp pot. .275 (6.98) MAX. .475 (12.06) MAX. Guide Posts Polarizing Posts 3. With firm steady pressure, push the contact into the cavity until the resilient internal shoulder snaps into the locking groove in the contact. To prevent over insertion, the tool tip bottoms against the rear of the insulator. 4. The guide post and polarizing posts are inserted in teh same manner as the contacts. The guide posts are inserted into the socket insulator, and the polarizing posts are inserted into the pin insulartor. The corresponding contact in the mating insulator must be removed for each. EXTRACTION Microminiature D 1. To extract the contacts, place the conector face up in the assembly block so that the contact to be extracted is in the end of the block that has a fully slotted opening. 2. The pin extraction tool tip is tubular, slides over the pin bundle and butts against the front shoulder of the pin. The socket extraction tool is a solid rod that fits into the socket contact, the external shoulder butts against the contact socket shoulder. 3. Insert the extraction tool into the cavity and apply firm pressure until the contact is pushed thru the rear of the connector. 4. Lift the insulator from the groove and pull the contact out. Repeat for balance of contacts to be removed. Dimensions shown in inches (mm) Specifications and dimensions subject to change D-88 www.ittcannon.com
