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.

EXPlora

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.

E-T-A Type 1626, Low-Cost Miniaturised Circuit Breaker for Automotive and Watercraft Applications

October 19, 2009

eta logo.jpg

Blade-type fuse replacements distinguish genuine overloads

E-T-A Circuit Breakers, quality designer and manufacturer of a broad range of electro-mechanical and electronic products for circuit protection, has introduced a new low cost E-T-A 1626 miniaturised circuit breaker designed as a direct replacement for blade-type fuses. It provides superior protection to fuses through its ability to distinguish between temporary surges and genuine overloads. As well as protecting electrical circuits in cars, trucks and buses, it can also be used in watercraft and other 12/24V DC wiring applications, such as heavy-duty and off-road vehicles.

1626

The new blade-type E-T-A 1626 Mini-CBE is available in three versions – with automatic reset, with a reset button, or with both a manual release and a reset button. The colour coded E-T-A 1626s are available in all the standard current ratings offered by blade fuses from 5A up to 30A. Depending on the version, when the 1626 has tripped it resets automatically when the load is removed or the re-set button pops up showing clearly which circuit has a fault.

The colour coding provides quick and easy identification to ensure correct plug-in placement in standard ISO 8820-3 Type F automotive blade-type fuse blocks, or the E-T-A 1626 can be fitted to purpose-designed E-T-A modular mounting bases. At the same time, the electrical performance characteristics of the E-T-A 1626 enable it to distinguish between temporary surges and genuine overloads, providing superior protection to fuses. This is especially important for motors, lamp loads and other circuits where discrimination is necessary between in-rush currents and normal operating conditions. Also, E-T-A circuit breaker performance is stable over time: fuses can age, causing their blow characteristics to change, which may lead to nuisance blowing of fuses with consequent problems while the vehicle is in use.

Overall dimensions of the body of the overcurrent circuit breaker are just 25mm in height above the blade x 13.3mm wide x 7mm thick. The operating temperature range is -40 degrees C to +85 degrees C.

Honeywell Introduces Upgraded ASDX Series Ultra-Low-Pressure Silicon Pressure Sensors

October 16, 2009

Logo.jpg

Devices Provide Enhanced Performance, Accuracy, and Sensitivity While Lowering Integration Costs

Honeywell has expanded its industry-leading ASDX Series silicon pressure sensor portfolio with ultra-low pressure ranges that include 0 to 10 inches of H2O gage, ± 10 inches of H2O differential, and ± 5 inches of H2O differential. These sensors include additional signal conditioning integrated within the product, allowing customers to remove components associated with signal conditioning from their PC board to free space and reduce costs normally associated with those components.

ASDXO

The Application Specific Integrated Circuit (ASIC)-based design provides a fast, highly accurate, amplified, conditioned pressure reading. Ratiometric 12-bit analog output for reading pressure over the specified full scale pressure span and temperature range allows for fast and easy integration into standard electronic circuits, and 12-bit I2C or SPI digital interface for reading pressure over the specified full scale pressure span and temperature
range minimizes connections and provides higher resolution and faster performance through reduced conversion requirements and the convenience of direct interface to the microprocessors and microcontrollers.

The ASDX Series achieve a tight total error band of ± 2.0% of full scale span maximum, providing enhanced sensitivity and accuracy even at ultra-low pressure ranges. Custom calibration ranges (inches H2O, psi, mbar, bar, kPa), supply voltage of 3.3 Vdc or 5.0 Vdc, and absolute, differential, and gage pressure types expand application opportunities.

These ultra-low pressure sensors are intended for use with non-corrosive, non-ionic working fluids, such as air and dry gases. The ASDX Series pressure sensors are fully calibrated and temperature compensated for sensor offset, sensitivity, temperature effects, and non-linearity. Calibrated output values for pressure are updated at approximately 1 kHz.

The ASDX Series silicon pressure sensors may potentially be used in industrial and medical applications including barometry, flow calibrators, gas-flow instrumentation, sleep apnea/therapy equipment, pneumatic controls, and ventilation/airflow monitors.
