Order now Distributor List Contact Sales LTC - Traction current sensors The LTC current transducers are meticulously optimized for the electronic measurement of DC, AC, and pulse currents while maintaining galvanic isolation between the primary and secondary circuits. These sensors are specifically engineered for traction applications, ensuring efficient operation in both fixed installations and onboard trains.

The LTC railway current sensors are modular and compact sensors that offer flexibility in their mounting. They can be installed either horizontally or vertically, and the feet can be mounted in three different ways, creating three possible vertical mountings. Additionally, the busbar can be mounted in two different ways, catering to customer preferences.

The LTC Series operates based on the closed-loop Hall effect sensor principle, which guarantees excellent accuracy and rapid response times. This technology makes these sensors reliable and well-suited for the demanding requirements of railway applications.
