The correct choice of sensor is always a prerequisite to achieving a successful solution. Our A5S speed sensors are based on the proven Differential-Hall-Effect principle. Their low end of 0 Hz allows monitoring the machine down to zero speed. They are contact-free, wear-free, maintenance-free and unsusceptible versus external magnetic stray fields and machine vibration. These characteristics make the series of A5S sensors especially suited to all applications where high levels of accuracy and reliability are at a premium. In contrast, other sensors like magnet-inductive or static Hall-sensors do not meet these demands.
Virtually any steel profile can be detected: fine or coarse, helical or straight gear wheels, nuts or pole wheels with small or large cams.
The speed range spans an area from a stationary state up to 25 000 pulses per second (0 Hz…25 kHz), depending on the application.
Each sensor in the series is available in various lengths and diameters and comes with a choice of connections. However, functionally all sensors have the same characteristics. The stainless steel sensor housing is sealed at the front and is pressure resistant (> 200 bars). A flat shaft is available or with a screw-in thread M12x1, M14x1, M14x1,5, M16x1, M16x1,5, M18x1, M18x1,5, M22x1, 5/8-18UNF-2A. Customized dimensions and thread specifications are possible.
