Multi-axis force sensor

Crack propagation from stress concentrations in strain-gauge elements, result in poor performance. Advanced screen-printing technology and high tolerance resistance trimming, eliminating laser contact to reduce cracking, and yield a more robust design.

A ceramic-cross strain gauge senses two or three axes of user input. Sensing elements, screen printed on the mounting substrate, interface with IBM Track Point(TM) cursor-control code and the new Philips TPM microprocessor.

Z-axis sensing element uses dedicated half-bridge to deliver output proportional to force. Available in PS2 or RS232 output, with unlimited customization options.
