From the International Electrotechnical Commission webstore:
“IEC/PAS 61076-3-119:2013(E) establishes specifications and test requirements for a connector with ten contacts for use in industrial environments. This PAS specifies free and fixed connector inserts with round contacts suitable for screw or crimp terminations. Other terminations techniques, as solder or printed board connections are upon agreement between manufacturer and user. The free and fixed connectors have a push-pull locking mechanism for IP65 and IP67 protection according to IEC 60529. Connectors according this PAS are without breaking capacity COC according to IEC 61984, therefore they are not intended to be engaged or disengaged in normal use when live or under load, if not otherwise specified by the manufacturer.”
