Outline Dimension Drawing

Application
TQG15 products are photoelectric rotation speed sensors, which are applied for measuring
wheel speed of locomotive, providing electric controlling system with pulse signal in proportion
with wheel rotating number. They also can be used in other locomotives or industrial machine
tools that have installation device and need to measure rotation speed.
