Everything about autosen


Use the AR001 to evaluate your rotational speed. Exceeded or not reached target values of rotating or linear movements are reliably detected. The speed monitoring is carried out according to the inductive measuring principle. This means that all metals are detected without contact and without wear.

The AR001 speed monitor has a sensing range of 12 mm and can be operated as normally open or normally closed. The setting range can be configured comfortably from 3 to 6000 pulses per minute via a teach button. The AR001 has two outputs so that the pulse sequence is provided separately and simultaneously to the set speed monitoring.

The AR001 speed monitor from autosen is ideal for speed monitoring tasks like detection of underspeed or blockage on elevators, conveying or ventilation systems. The adjustable start-up delay prevents incorrect switching when the machine to be controlled is started. Clearly visible LEDs indicate the operating and diagnostic states of the speed monitor. The locking function prevents unauthorised changes on the sensor during operation.

Tried-and-tested millions of times in daily use. Speed monitors from autosen are manufactured according to the highest quality standards with regard to robustness, noise immunity and reliability. We offer you a 5-year warranty for our product – with money-back guarantee!
