Reliable power and signal connections in hazardous areas

29 October 2009

Ensuring reliable power and signal connections to portable instruments is a challenge for manufacturers, especially where dampness and explosive gasses may be present. Fern Communications has overcome this on their FRX1 radio signal repeater with the use of InstrumEx connectors from Hawke International.

Hawke's InstrumEx connectors provide a convenient secure and Ex compliant cable connection and so play a key role in maintaining the integrity of the FRX1. The InstrumEx connector is ATEX and IECEx compliant and allows live connection and disconnection of circuits in zones 1, 2, 21 and 22. Integral to the design is the Hawke cable gland which has features for secure clamping of all wire armour and braided cable types.

All connectors have heavy-duty, maintenance-free, nickel plated brass or stainless steel shells to give ingress protection to IP66/67 and DTS01 and include models for in-line and bulkhead applications. They have a keying system which prevents possible misconnection and safeguards the contacts from damage. Reliable low resistance connections are ensured by the use of Multilam Technology which requires less force to engage or disengage the gold plated multi-pin connections.
