11、d open ends. Intended for use with single or double-sided printed boards of 1.42 mm to 1.80 mm thickness. The connectors are available in sizes up to a maximum of 85 contacts per side with three different seated height styles. Front or rear removable/replaceable contacts are available in the connect
12、or range with front or rear release for each direction of removal. Replacement contacts and keys used with ranges of connectors shall be identical to the originals. The method of contact removal and replacement and the tools required will depend upon the design of individual connectors. The mandator
13、y method of location is by a guide key which replaces an opposite pair of contacts and one such key shall be provided per connector. (See clause 9.)
