VLS Optical Speed Sensors - VLS
The VLS Series Optical Speed Sensors are primarily designed for speed related use. They are ideally used with our range of Digital Tachometers, including handheld, panel mounted and bench style instruments, A range of mounting devices is available for hands free applications: brackets, clamps, fixed focus lens for high speed, and small shafts.
Mains and Battery Pack: A suitable mains adaptor / battery pack is available for use with all VLS5/D models.
Optical Ranges: Up to 2 meters with reflective tape.
High Speed Applications: A clip on pre-focused LN1 Lens Adaptor is available which can allow operation without reflective tape with certain applications.
Power Options: The VLS Series Optical Speed Sensors are available in 4-40vdc powered options; see the buying guide for more information.
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.
