AMS 2140 Laser Speed Sensors
Laser Speed Sensor uses a laser in conjunction with advanced signal processing to measure turning speed without requiring any special markings on the shaft.
Range is typically 30ft without reflective tape or 100ft with reflective tape. This sensors is intended for use with AMS 2140.
