All numerical values are in metric units [with U.S. customary units in brackets]. Dimensions are in millimeters [and inches]. Unless otherwise specified, dimensions have a tolerance of ±0.13 [±.005] and angles have a tolerance of ±2°. Figures and illustrations are for identification only and are not drawn to scale. 1. INTRODUCTION This specification covers the requirements for application of AMPMODU Short Poi nt contacts and housings for cable-mount applications. These components mate with printed circuit (pc) board mounted 0.64 mm [.025 in.] The contacts are available in duplex 30m gold, 15m gold, or 100m tin. Each contact features a locking lance to engage the housing and two spring members to engage the mating post contact. The contact is available in three sizes: 32-28, 26-22, and 24-20 AWG. Strip-form contacts are designed for automatic machine application and loose-piece contacts are designed for hand tool application. The housing is made of flame retardant black thermoplastic. Each housing has double row contact cavities with in-row and row-to-row centerline spacing on 2.54 mm [.100 in.], and are available in 4- to 52-position configurations. They can be mounted side-to-side or end-to-end while maintaining the same centerline spacing. NOTE AMPMODU Short Point contacts can also be used in single row, 2- through 25-position AMPMODU MTE housings. These housings are available with plain exterior surfaces which allow for continuous 2.54 mm [.100 in.] centerline spacing with guiding ribs to mate with shrouded pc board headers or with polarizing ribs and latches for free -hanging assemblies. For more information on the MTE housing, see Application Specification 114-25026.

REQUIREMENTS 3.1. Storage A. Ultraviolet Light Prolonged exposure to ultraviolet light may deteriorate the chemical composition used in the product material. B. Reeled Contacts When using reeled contacts, store coil wound reels horizontally and traverse wound reels vertically.
C. Shelf Life The product should remain in the shipping containers until ready for use to prevent deformation to components. The product should be used on a first in, first out basis to avoid storage contamination that could adversely affect performance. D. Chemical Exposure Do not store product near any chemical listed below as they may cause stress corrosion cracking in the material. Alkalies Ammonia Citrates Phosphates Citrates Sulfur Compounds Amines Carbonates Nitrites Sulfur Nitrites Tartrates NOTE Where the above environmental conditions exist, phosphor-bronze contacts are recommended. 3.2. Wire Selection and Preparation The contacts will accept solid or stranded wire sizes 32 through 20 AWG with a maximum insulation diameter Proper strip length is necessary to properly insert the wire into the contact. The strip length of the wire is shown in Figure 2. CAUTION When stripping the wire, care must be used to avoid scraping, nicking, or cutting the conductor. Care must also be used when handling the wire during stripping and crimping to prevent cracking or breaking of the conductor and insulation. CONTACT SIZE WIRE SIZE (AWG) 32-28 26-22 24-20 Figure 2 NOTE: Not to Scale Strip Length 1.52 [.060] Max Insulation Diameter Wire Conductor (Stranded Shown)
3.3. Crimped Contact Requirements The contact must be crimped to the wire according to instructions packaged with applicable tooling. NOTE Wire stripping tool jaws may leave corrugated indentations on the surface of the wire insulation. This is especially severe with cross-linked polyethylene (high temperature) insulation. If these indentations occur at the location of the wire seal, leakage may result. Insulation surface within 8.89 [.350] from the tip of the contact must be smooth and free of indentations. See Figure 3. A. Crimped Configuration and Location The wire barrel will be crimped in the F-crimp configuration where the tips of the wire barrel will turn inward and capture all wire strands. The insulation barrel will be crimped to the O -crimp configuration where the tips of the insulation barrel will overlap and capture the wire insulation and form the insulation support. The effective crimp length (excluding bellmouths) over the length of the wire barrel shall be within the limits shown in Figure 3. B. Wire Barrel Seam The wire barrel seam shall be completely closed with no portion of the conductors protruding from the seam. See Figure 3. C. Crimp Height and Width The crimp applied to the wire portion of the contact is the most compressed area and is the most critical in assuring optimum performance. The crimp applied to the contact must be within the range specified for each wire size as specified in Figure 3. D. Bellmouth The front and rear bellmouths caused by extrusion of the contact metal during the crimping process shall be within the limits provided in Figure 3. E. Cutoff Tab and Burr The front cutoff tab must not extend beyond the contact box and the rear cutoff tab must not extend beyond the insulation barrel more than the limits specified in Figure 3. Burrs resulting from the shearing of the cutoffs must not exceed the limits shown in Figure 3. F. Flash Flash that may appear on either side of the crimped contact shall not exceed the maximum limit specified in Figure 3. G. Conductor Location The conductor of the wire must be flush or within the protrusion limit specified from the front of the wire barrel. Both insulation and conductor must be visible in the transition area between the insulation barrel and wire barrel. No insulation must be in the wire barrel. See Figure 3. H. Locking Lance Inspection of several uncrimped contacts will provide a visual reference for the contact. The height of the locking lance, measuring from the contact box, must be within the specified limit provided in Figure 3.

3.5. Repair and Replacement The contacts and housings are not repairable. Any defective or damaged contacts or housings must be discarded. Contacts must not be reused by removing the wire. NOTE If a damaged contact is apparent before the contacts are inserted into the housing, cut the wire in back of the contact and reterminate the wire end. If contacts or housing are damaged after insertion, the wire must be cut directly in back of the housing and reterminated with new contacts and housing. See Section 5, TOOLING. 4. QUALIFICATIONS AMPMODU Short Point contacts and housings do not require agency evaluation . 5. TOOLING The contacts can be terminated to wire using a hand crimping tool or semi-automatic machine. The wire size range of the contact will determine the tooling to be used. After a contact is crimped, it can be inserted into the housing without the use of a tool. Tooling part numbers and instructional material packaged with the tooling are shown in Figure 6. 5.1. Extraction/Lance Reset Tool This tool is designed to release the contact locking lance through the locking lance window of the housing without overstressing the locking lance. It can also be used to reset locking lances that have been deformed. 5.2. Hand Crimping Tools Hand crimping tools have been designed for prototype and low-volume application of loose-piece contacts. 5.3. Power Units The power units are semi-automatic machines used to assist in the application of the strip-form contacts. Power unit includes the power source used to supply the force or power to the applicator. 5.4. Applicators Heavy-duty quick-change miniature applicators have been designed for high-volume production. The applicators are adjustable for the full wire size range of strip-form contacts. Contact Locking Lance Locking Lance Window of Housing Contact Cavity of Housing Wire
