C 4 Requirements 4.1 Storage A. Ultraviolet Light Prolonged exposure to ultraviolet light may deteriorate the chemical composition used in the contacts. B. Shelf Life The contacts should remain in the shipping containers until ready for use to prevent deformation to the contacts and/or damage to the housings. The contacts should be used on a first in, first out basis to avoid storage contamination that could adversely affect signal transmissions. C. Chemical Exposure Do not store contacts near any chemicals listed below, as they may cause stress corrosion cracking in the contacts: Alkalies, Ammonia, Citrates, Phosphates Citrates, Sulfur Compounds, Amines, Carbonates, Nitrites, Sulfur Nitrites, Tartrates. 4.2 Materials The pin and socket contacts are made of copper alloy with tin plating. 4.3 Wire Size and Preparation (see item 6 - connector assembly procedure - for more details) The contacts will accept a wire size range from 1.5mm to 2.5 mm and have to be terminated to stranded wire See Figure 2. Fig. 2 The conductor section area and outer diameter of the wire must be in according to the terminal drawing. The insulation must be cut uniform and torn off the conductor. No remainders of the insulation are allowed on the stripped conductor single strands of the conductor may neither be cut nor damaged nor pulled during stripping operation. After pull off the insulation sleeve the single strands of the conductor may not split open. Separated single strands are not allowed. The strands of the conductor are not allowed to be twisted. If the stripped wire isnt crimped immediately, the stripped conductor end is to be protected against dirt splitting off of the single strands, for example by partial pull off the insulation sleeve. Any protruding wire strands must not impede the mating and basic function of the contact. Rev. C 2 of 28
