frequency switch | LABO-D...-S

Produktbeschreibung

general information:

The LABO-D...S frequency switch combines a primary sensor with evaluation electronics with a powerful 16-bit microcontroller in the housing of a proximity switch. The evaluation electronics enable, for example, the speed measurement of rotating machine parts, turbines, spinners, etc. by means of the detection of the approach of metals or magnets in various environments and the evaluation of the resulting frequency.

The primary sensors are available with various technologies depending on the application:

magnetic field sensors are capable of detecting the approach of magnets. This is also possible through metallic surfaces.
pre-tensioned hall sensors detect the approach of ferromagnetic metal parts, even through metallic but non-ferromagnetic surfaces.
inductive sensors detect the approach of all types of metal parts and can therefore not be used behind metal surfaces.

The LABO electronics provide an electronic switching output (push-pull) with adjustable characteristics (minimum/maximum) and hysteresis, which responds when a value falls below or exceeds an adjustable limit.

If desired, the switching value can be set to the currently existing frequency using "teach-in". Switching and switch-back times can be adjusted independently of each other. The power-on-delay function makes it possible to keep the switching output in a defined state for a variable time after the supply voltage is switched on.

Models with analog or pulse output are also available.
