The Compact VLS 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.
