Membrane keypad for measuring and testing technology

THE REQUIREMENTS:

Precise alignment of machines in industry pays off, because according to a statistical survey, around 50% of all machine failures are due to inadequate alignment.

The ROTALIGN Ultra laser-optical precision alignment device from our customer Prüftechnik Alignment Systems GmbH makes it possible to reliably avoid misalignment and achieve precise alignment of machines.

Hoffmann + Krippner GmbH & Co. KG & Co. KG’s requirements for an operating unit that could be used intuitively and was reliable at all times were particularly high: the keypad had to allow alphanumeric input, have backlighting, be dust and splash-proof according to IP65, and also be equipped with LEDs.

THE IMPLEMENTATION:

Complex solutions and individual engineering are the strengths of Hoffmann + Krippner GmbH & Co. KG & Co. KG. Thus, within a very short time, a high-quality and, above all, reliable operating unit was developed for Prüftechnik Alignment Systems GmbH. The design of the backlit, alphanumeric membrane keypad was selected according to ergonomic considerations and is divided into three areas: navigation, data entry and function keys.

The GT technology developed by Hoffmann + Krippner ensures very good haptics even under extreme conditions. The keyboard is mounted on a printed circuit board and is dust and splash-proof according to protection class IP 65. Two additional LEDs integrated into the keypad evaluate the alignment status without delay as a function of specified tolerance tables. The keypad is connected to the alignment device by means of a zero-force connector and can thus be easily mounted and integrated by the customer.
