TQG15DA3-XC Electronics

Speed Sensor ：TQG15DA3

Photoelectric | High-Performance | Durability

The TQG15DA3 speed sensor utilizes the photoelectric effect, converting locomotive speed into a square-wave pulse signal (f = n × p / 60). It features polarity protection and short-circuit protection, offering excellent performance and strong operational stability, and is widely used for speed measurement in electric locomotives.
