Bulgin connectors suit hazardous environments
Bulgin Components
Explora connectors
Bulgin Components has announced the Explora series, a range of connectors designed for use in hazardous environments.
Independently tested for compliance to ATEX standards for use in Zone 2 and Zone 22 environments, the Explora series is manufactured from a tough, high-grade UL94V-0-rated Polycarbonate material.
Similar in construction to Bulgin’s 900 Series Buccaneer, the connectors are environmentally sealed to IP68 to provide protection for the most severe of dust- and waterborne environments.
Ambient temperature range is from -20 to 55C.
The ATEX coding is Ex II 3 GD and the certificated no is Baseefa09ATEX0232X.
Compact in design, the connectors are available in two-, three-, four-, five-, seven- and 10-pole variants and in four body styles - cable, in-line cable, panel and flange fixing.
Each contact insert is available with pin or socket contacts and can be used with any of the body styles to give the maximum choice of combinations.
They are rated up to 18A, 600V AC/DC for two, three, four and five poles, 16A, 430V AC/DC for seven pole and 10A, 250V AC/DC for 10 poles.
The three-, four-, five- and seven-pole versions have leading earth contacts, making them suitable for single- or three-phase applications.
The EXP series connector achieves an environmental seal to IP68 as soon as the locking ring is tightened, without any supplementary sealing.
Sealing caps with strong steel retaining cords maintain the sealing integrity when connectors are not mated.
The IP68 rating is tested submerged at 10m for two weeks.
Screw fixing terminal contacts, designed to accommodate conductors up to 4mm2, require no special tooling and allow the connector to be easily terminated and maintained in the field, while positive location keyways prohibit the possibility of misconnection.
Two designs of cable retention and alternative sealing glands allow for cable acceptance from 7mm through to 22mm diameter.
The connectors are designed for applications where a secure, reliable and easy to terminate interface is required, particularly for manufacturers supplying machines, equipment and systems where explosive atmospheres might exist.
As well the petrochemical industries, this could include mills and grain stores, paint and ink manufacturers, timber mills and processors, cement works, shipyards and sewage treatment.
The Explora range is most suited to manufacturers of ancillary electrical equipment such as motors, pumps, lighting equipment, process and control gear for use in factories and plant where hazardous, or explosive atmospheres can be caused by flammable gases, mists or vapours, or by combustible dusts.
