InstrumEx Connectors - How It Works
The InstrumEx connectors are designed to provide ease of installation and speed of use, whilst providing a flexible safe and reliable method for mating and disconnection of circuits which are energised.
Stage 1
The two mating halves are easily engaged and disengaged by two full turns of the ACME custom engaging thread, during which time the pins and socket are protected by the Exd flameproof protection concept. The outer shell of the connector combined with the integral Hawke cable gland seal ensure that the internal connections are protected to the Exe increased safety protection concept.
Stage 2
During connector engagement and disengagement any sparking of the contacts is contained within an arc ‘quenching section’ which is housed within the Exd flamepath areas.
Stage 3
When the connector halves are disengaged, the socket section is protected to IP30 and must have the protective cap fitted immediately to restore the full Exe increased safety requirements and IP rating. The pins and socket inserts are interchangeable between all three connector components: i.e. Bulkhead Receptacle, In-Line Receptacle and Connector Plug. In all installations, the "live" side of the connector must always contain the socket insert.
