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 variant of its extremely versatile and reliable 3120 Series of rocker-actuated, combined switch / circuit breakers. The optional integral LED illumination in a range of colours that is now available on the Type 3120 offers power saving and improved endurance compared to earlier versions with filament bulbs. The well-proven 3120 is used widely for applications which include electrical machinery, power tools, household appliances and garden machinery, as well as for marine control panels, medical equipment and communications systems.

The versatile S-type E-T-A 3120 thermal circuit breaker range is designed for frequent ON/OFF switching under normal load conditions, at the same time providing accurate overcurrent protection with a trip-free mechanism. The illumination is offered in a choice of red, yellow, green and blue. The 3120 is suitable for switching applications up to 50V DC or 240/415V AC with a choice of current ratings from 0.1A up to 20A for single or double-pole applications. Designed for snap-in frame mounting, it can be specified with a water splash protection cover for rugged environments, and an actuator guard that protects against inadvertent resets.

The new LED versions require less than 2mA in operation, compared to earlier versions with filament bulbs which required between 20mA and 60mA. Improved illumination endurance, as well as reduced susceptibility to shock, vibration and low temperatures, also means lower maintenance requirements.

The E-T-A 3120 range carries EN 60934 Circuit Breaker for Equipment approval as well as approvals from respected authorities such as UL and CSA. The 3120 provides proven reliability for many demanding applications, including recreational and workboats as it is suitable for even the harshest conditions experienced at sea.

Pressure Ranges from 1 to 5 psi, On-Board Signal Conditioning, Custom Calibration,
and Digital Output Options Provide Support for Many Unique Applications

Honeywell has expanded its industry-leading ASDX plastic silicon pressure sensor family with the new ASDX Series and ASDX-DO Series, which offer pressure ranges from 1 psi to 5 psi and on-board signal conditioning.

The on-board signal conditioning allows the customer to remove those components from their PC board to free space, may reduce their acquisition, inventory, and assembly costs, and minimize potential problems from having multiple signal conditioning
components spread across a circuit board.

These low-pressure sensors are intended for use with non-corrosive, non-ionic working fluids, such as air and dry gases. Potential industrial and medical applications include barometry, flow calibrators, gas-flow instrumentation, sleep apnea/therapy equipment, pneumatic controls, and ventilation/airflow monitors.

The ASDX and ASDX-DO Series pressure sensors are fully calibrated and temperature compensated for sensor offset, sensitivity, temperature effects, and non-linearity using an on-board Application Specific Integrated Circuit (ASIC). Calibrated output values for pressure are updated at approximately 1 kHz.

The ASDX Series with compensated analog output provides a ratiometric 12 bit analog output for reading pressure over the specified full scale pressure span and temperature range, typically allowing for fast and easy integration into standard electronic circuits. The ASDXDO Series with compensated 14 bit digital output provides either an I2C or SPI digital interface for reading pressure over the specified full scale pressure span and temperature range, minimizing connections, providing higher resolution, and faster performance through reduced conversion requirements and the convenience of direct interface to the microprocessors or microcontrollers.

The low-leakage filter FN 2450 expands the Schaffner product offering of suppression components in plastic housings, which optimally combine innovative lightweight designs with a high level of functionality, safety and ergonomics.

The innovative use of plastic materials and the elimination of potting compound allow a significant weight reduction, in comparison to conventional EMC/EMI component designs. The EMC-compatible HF contact to ground is ensured by a metal base plate.

Integrated terminals in the housing enable reliable contact from the top with the automatic torque wrench. Built-in safety covers, which for the purpose of installation can be easily folded forwards and backwards using a captive swivel mechanism, are provided as standard for protection against unintended contact with live clamping elements.

The low-leakage EMC/EMI filters FN 2450 are designed for rated currents from 6 to 20A (at 55°C) and for single-phase networks ≤250VAC. All versions are distinguished by minimal filter leakage current and are particularly suited for use with sensitive residual current protective devices, as well as for strict requirements with regard to operator and fire protection. The compact filters are UL, CSA and ENEC approved and comply with the requirements of the RoHS directive.

Patent-pending, compact, high-functional density
design meets off-road vehicle requirements

Honeywell has introduced a new line of handlebar controls to meet off-road vehicle manufacturers’ desire for controls that are easily customized, incur low upfront tooling costs, enhance safety,and increase design flexibility.

Honeywell Sensing and Control’s new 1080HD Series Handlebar Controls provide off-the-shelf, SAE spec-qualified handlebar controls that provide a greater number of functions per package volume and are easily configured in different ways. With little up-front investment for the OEM, Honeywell’s platform approach creates a customized right or left-hand control in a cost-efficient, qualified handlebar control to support short OEM product design cycles.

The 1080HD Series offers enhanced safety through an optional runaway prevention switch, and through a smaller form factor that enables easier user access to critical vehicle functions.

To meet additional requirements for design flexibility and aesthetic differentiation, Honeywell developed three patent-pending designs that can be applied to the new handlebar controls. Common components and inserted tooling reduce
tooling investment and minimize procurement complexity while also improving manufacturability. The product’s smaller size and easy configurability increases OEM design flexibility in both functions and in attachment and accessory options. Standard
circuitry and components shorten OEM product development times, and the unique design specification meets most North American off-road and European on-road requirements.

These customized controls may be designed for use on appropriate vehicles with handlebars, including ATVs, snowmobiles, electric vehicles, Segway® mobile platforms, motorcycles, or standing, handle bar-maneuvered machines (i.e. industrial
sweepers, grocery/luggage cart collectors, etc.)
