The VLS Series sensors provide an NPN pulsed output for each rotation of a rotating object. Maximum range is up to 250,000 rpm. This is ideal for data-logging applications and where general speed monitoring of machines is required, it is particularly useful for monitoring & recording RPM or rotational speed data. Units are available with a visible light optical sensor, or a laser light for a greater optical range and better response. Reflective tape can also be used to improve the accuracy. A selection of mounting brackets, contact adaptors and focusing lens are available to allow for easier installation, high speed measurements and smaller focus points.
Optical Ranges: Up to 2 metre (up to 1m with visible light) with reflective tape.
High Speed Applications: A clip on pre-focussed LN1 Lens Adaptor is available which can allow operation without reflective tape in certain controlled conditions.
Power Options: The VLS Series Optical Speed Sensors are available in 5vDC and 7.5-40vDC powered options, normally provided by the associated instrument from our range.
Contact Adaptor: The contact adaptor converts the optical function into direct shaft contactor for both RPM and linear speed measurement, this bayonet fitting device operates via a Hall Effect magnetic sensor built into the Sensor housing which picks up from a magnet in the VLS sensor.
Accessories must be ordered separately for the VLS Sensors A range of mounting devices is available for use with these sensors, brackets, clamps, fixed focus lens for high speed and small shafts.
