Bulgin Introduces Over-Moulding Cable Connectors to Extend the 400 Series Buccaneer Applications

April 29, 2009

Bulgin_Logo_150px.gif

The number of uses for Bulgin’s 400 Series Buccaneer waterproof connectors has grown with the introduction of fully assembled cables using over-moulded cable connectors.

Using over-mould technology a secure, reliable and tamperproof cable termination is created which is dust and waterproof to IP68.  The two new cable connectors, PX0400 - flex, and PX0401 - flex in-line, allow secure connections to be made with in-line cable assemblies or cable to panel assemblies and are completely compatible with the current 400 Series panel connectors PX0412 and PX0413.

Over-moulding also provides a strong, durable strain relief around the cable functioning through a temperature range of -20°C to +85°C, while the polyurethane over-mould material has been tested and validated for use on PVC and polyurethane cable jackets.

These cable assemblies provide a secure interconnection system for OEM’s who may require a ‘customer-proof’ solution, so are ideal for ‘fit and forget’ applications such as instrumentation, marine, medical, surveillance and CCTV.

The wide range of potential options, including cable construction, length, number of poles, flex or flex in-line connectors, may be combined with any other type of connector to provide an assembly to meet exact system requirements.

Schurter's New 5150 Type Filter Offers a Simple Solution for Ghz Applications

April 29, 2009

Schurter Logo1.jpg

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.

E-T-A Introduces the New ESX10 Type Rail Mounted Variant for Electronic Overcurrent Protection in Automation Applications

April 28, 2009

 eta logo.jpg

E-T-A Circuit Breakers has introduced a new version of its compact ESX10 electronic overcurrent protection product for automation applications. Designed to reduce costly downtime and danger to personnel on production lines, the new ESX10-T is ready for direct rail mounting, singly or in groups. Single or group signalisation is quickly attainable.

The type ESX10 Electronic Circuit Breaker provides electronic overcurrent protection according to UL2367 for 24V DC control circuits and load currents from 1A to 12A: in the event of overload or a short circuit, the faulty load will be disconnected electronically by means of a mosfet in the output circuit of the protector. It ensures selective disconnection of 24V DC switch-mode power supply (SMPS) loads while optimally matching the application requirements.

ESX10.jpg

The E-T-A ESX10 provides active current limitation to 1.8 or 1.5 times its rated current. This allows capacitive loads of up to 20,000μF or lamp loads to be switched on without affecting other loads on the power supply. At the same time, this electronic active current limitation responds much faster to overload or short circuit conditions than switch-mode power supplies: the ESX10 will shutdown electronically a single faulty output, while allowing all other load circuits connected to the same SMPS to continue working as normal.

The E-T-A ESX10-T is just 12.5mm wide and can be mounted directly on a DIN/EN rail. All electrical connections are then made by means of convenient screwless terminals. Status indication is provided by a multicolour LED plus an integral short-circuit proof status output or potential-free signal contact. In the event of an overload or short circuit, the load circuit may be re-activated electronically via a re-set input, or by a manual ON/OFF button. The ON/OFF button also allows manual disconnection when starting up a system or during maintenance.

For processes powered by 24V DC switch-mode power supplies without circuits protected by a device such as the ESX10, an overload in a single circuit will cause the power supply to shut down the output to all the circuits it supplies. On recovery it may go into ‘hiccup’ mode. Costly downtime, scrap and even danger to personnel may result. Traditional protection solutions do not provide the answer. Circuit breakers with fast operating characteristics would be likely to cause nuisance trips during current peaks and switching on of capacitive loads. On the other hand MCBs are too slow, and neither delayed operation nor high performance circuit breakers will respond adequately in this situation to overcurrents. The power supply will therefore switch off completely, bringing all connected loads, i.e. the entire system, to a standstill.

Arcolectric's 8200 & 8300 Miniature Push Button Switches Have Higher Current Ratings.

April 15, 2009

ARCOLOGO-2004_140px1.gif

Arcolectric's 8200 & 8300 Miniature Push Button switch ranges now have higher current ratings. Both ranges have been re-assessed for ENEC approval to 12(12)A 250Vac at 105?C for 10,000 operations.

The extensive 8300 range is available with either illuminated or non-illuminated buttons, in single or double pole with momentary or latching switch action. There are options for various switching functions, terminal styles - including push on, solder and PCB terminals, along with options for actuators, body finish, colours and legend printing.

8300 Series.jpg

The 8200 range is sub panel mount with a choice of actuator types and terminal styles and orientation, these include push-on, solder and PCB terminals.

Both ranges have UL & CSA approval, as well as ENEC approval to the new higher current rating.

This higher inductive rating further extends the applications for these two families of switches into motor switching applications where the initial switching current can be far higher than a resistive load.

Schurter FMEB & FMEC Filters - Less Noise and More Stable DC Power Distribution

April 14, 2009

Schurter Logo1.jpg

Schurter extends its range of DC rated filters with the introduction of series FMEB and FMEC. These filters are especially optimised for use in DC applications, particularly those requiring increased attenuation of asymmetric disturbances. 

 FMEB FMEC.jpg

Applications include DC supplied IT and telecom infrastructures, as well as branch and automation control circuits for the machine and transportation industries. When used in the electrical supply cabinets, the filters guarantee safe operation of the system by attenuating external disturbances.

The filters have a current rating of 30 A at 80 VDC and are offered in single and dual polarity output circuits. The single polarity FMEB filter is designed for a maximum operating voltage of 80 VDC, while the FMEC series offers connections for two polarities for a maximum + 80 VDC. The aluminium housing is potted and has metal flanges for secure mounting to the chassis. The input side is equipped with screw clamps and the output has 6.3 mm x 0.8 mm quick connect terminals. Other terminal configurations are available upon request.
