For use in extreme ambient conditions, particularly outdoor applications.

With the new piezo keypads SCHURTER provides key panels that are impervious to all kinds of dirt and fluids. The keypads are particularly suitable for use in outdoor applications due to their ability to resist extreme ambient conditions such as negative temperatures, ice and snow. The keypads fulfill the IP69K protection class and have a reliable operating temperature from -25°C to + 85°C. The accessory kit from SCHURTER enable the keypad to be sealed into the housing with the IP68 protection class. The piezo keypads can be mounted into the housing from the front or
the rear.

Piezo_Keypad

As a standard, the keypads are available as a number block with 12 or 16 keys and with an aluminium front. Point illumination may be integrated into the individual key fields as optical feedback or for user navigation. The operating panel can be designed in several colours in both the aluminium and stainless steel versions. In addition, SCHURTER can provide keypads that are adapted to customer requirements with respect to outer geometry as well as to the number and arrangement of the keys.

By using the piezo principle, the keypads are free of mechanical parts and therefore have an extremely long lifetime of more than 20 million actuations.  The completely sealed operating panel is easy to clean and is resistant to common cleaning agents. The metal surface with an IK05 impact strength renders the keypads highly resistant to impacts from outside. The piezo keypads provide a high level of functional reliability, leading to a reduction in maintenance costs.

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.

ASDX.jpg

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.
