Bulgin Components is pleased to announce a new range of connectors designed for use in hazardous environments - the EXPlora series.

Independently tested for compliance to ATEX standards for use in Zone 2 and Zone 22 environments, the new EXP series is manufactured from a tough high grade UL94V-0 rated Polycarbonate material. Similar in construction to Bulgin’s popular 900 Series Buccaneer, the connectors are environmentally sealed to IP68 to provide protection for the most severe of dust and water borne environments. Ambient temperature range is from –20°C to +55°C.

The ATEX coding is: Ex II 3 GD and the certificated no: Baseefa 09ATEX0232X.

Compact in design, the connectors are available in 2, 3, 4, 5, 7 and 10 pole variants and in four body styles - cable, in-line cable, panel and flange fixing. Each contact insert is available with either pin or socket contacts and either can be used with any of the body styles to give the maximum choice of combinations.  They are rated up to 18A, 600Vac/dc for 2, 3, 4 and 5 poles, 16A, 430Vac/dc for 7 pole and 10A, 250Vac/dc for 10 poles. The 3, 4, 5 and 7 pole versions have leading earth contacts making them suitable for single or three phase applications.

The EXPlora 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 mis-connection. Two designs of cable retention and alternative sealing glands allow for cable acceptance from 7mm through to 22mm diameter.

The connectors are designed for a wide variety of applications in mind, where a secure, reliable and easy to terminate interface is required, particularly for manufacturers supplying machines, equipment and systems where these 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.

Schurter presents a breakthrough product, providing simple and universal EMC for high frequency applications, using X2Y® filter technology. Series 5150 possesses broadband suppression properties to 1 GHz and combines them with the most simple and universal power input.  This integrated and compact design provides an easy, safe and cost effective alternative to existing market solutions and opens new opportunities in the filtering of high frequencies.

Until now, X2Y® filter technology is known only for EMI protection in DC circuits. With the introduction of the Schurter 5150 series, the application of X2Y® is now extended to the area of AC power input. The technology is applied in place of X and Y capacitors, typically used in line filters today. It combines the X and Y capacitors into one component, thereby eliminating the leads connecting the capacitors and reducing parasitic impedances to a minimum.  This results in broadband suppression into high frequency ranges.

The double shielding between the X2Y® filter and filter casing, together with the broad metal flange can serve as an alternative for feed-through and multi-stage filters.  The compact package is designed for front- or rear-side mounting and uses the same panel cutout size as a typical filtered AC inlet. Filter variations include types for standard, medical and industrial applications.

The breakthrough design of the 5150 is the first of its kind to be safety agency approved for use in AC applications according to IEC and UL. It is ENEC approved up to 10 A 250 VAC and cURus approved up to 15 A 250 VAC.  Application examples include equipment for measurement engineering, data encryption, medical engineering, IT and telecommunications. It is suitable for use in office and medical applications in accordance with IEC/EN 60950 and/or 60601-1.
