general features of multipole connectors for industrial purposes Threaded cable passage in various Pg diameters(types with pre-code ”C”) or metricpassage (types with pre-code ”M”) inaccordance with EN 60423, for cable entrydevices in accordance with EN 50262(NPT threading on request), may belocated vertically, horizontally or frontally. Heavy duty enclosures in die-castaluminium alloy or self-extinguishingthermoplastic (CK and MK series).cRUus (E) certifiedWall mounting or bulkhead housings andhoods are available, with or without fixedcovers or with mobile protection covers.The types of enclosures CH-CA (Pg cableentries) and MH-MA (metric cable entries)have a tab that prevents the insertion ofinserts series CME (all) and CMCE (only16+2 poles), while CM (Pg) enclosuresseries and MM (metric) do not have anytabs and contain supplementary insulatingstrips inside. Stainless steel closure levers and springsguarantee a perfect closure and sealing. Locking device available in two versions,simple (with one lever), or double (with twolevers). Various types of handles are available: inself-extinguishing, thermoplastic materialreinforced with glass fibres; in die-castaluminium (for special use with temperaturesof up to 180 °C); monoblock stainless steelhandles (CK, CZ, MK, MZ enclosures andfor special uses with temperatures of up to180 °C). Unlosable insert fastening screws, withantiloosening flexible washer. Contacts position identified with numbersor codes on both sides of each insert andlaser printed or moulded. Contacts in silver or gold-plated brasswith connections to the conductors madevia unlosable unloosened screws, springterminal, crimping or incorporated 45°terminal block connectors (with screw orspring terminal). Earth terminal protection with wide contactsurface. Pegs and levers supplied with anti-frictionrings that facilitate closure and limit wearand tear. CE marking attesting conformity to therequirements of the Low Voltage directive73/23/EEC and its modification 93/68/EEC.general Metallic enclosures with a coated finish ofepoxy-polyester with high resistance tomechanical stress and external agents.Enclosures used with temperatures of upto 180 °C and in aggressive environmentsare treated with special coatings. Whereelectromagnetic compatibility is necessary:EMC enclosures with high conductivity andhigh corrosion resistance surfacetreatment. Inserts in self-extinguishing thermoplasticmaterial reinforced with glass fibres, ULapproved, with a limit working temperaturefrom -40 °C to +125 °C.The inserts CME (all) and CMCE (only16+2 poles) for 830V have a key thatprevents the insertion of inserts for useother than that prescribed (types CM - Pgand MM - metric).For some series, inserts in PPS(polyphenylene sulphide) may berequested for special uses with temperaturesof up to 180 °C. Polarized inserts with asymmetric guiderails for preventing incorrect coupling.The inserts have a mechanical durationequal to or over 500 coupling cycles. Inserts manufactured in conformity withEN 61984 (DIN VDE 0627 standard andare certified and identified with the ULand CSA marks. Special seal gaskets in vinyl nitrile elastomeror fluoro elastomer (on enclosures for usewith maximum temperatures of 180 °C andfor aggressive environments), in anti-aging,oil-resistant, fuel-resistant, together withthe cable entry devices (not supplied)provide an IP66 degree of protection forcoupled connectors.Special conductive seals for EMC enclosures.9
