Niterra launches line of ABS sensors with the NTK brand

New components expand the company's portfolio, which highlights the importance and functioning of the item

São Paulo, June 2023 - A Niterra, Japanese multinational owner of the NGK and NTK brands and specialist in components for ignition systems, announces the expansion of its sensor portfolio with the launch of the new ABS sensor line (Anti-lock Brake System) of NTK.

ABS sensor prevents locking of vehicle wheels, allowing directional control of the car. "When making a turn, there is a difference between the speeds of the wheels. When we apply the brake on a vehicle at the time of the curve the load transfer to the front axle occurs and the front of the car tends to go down.", diz Hiromori Mori, Technical Assistance Consultant at Niterra do Brasil.

According to Mori, if one of the wheels locks, There is a tendency for the vehicle to move forward and not make the turn. "The ABS will act on the wheel that is locking and release the brake pressure. In this way, The car will be able to maintain directional control and make the turn or dodge an obstacle smoothly."

Mori explains that there are two types of ABS sensors:

• Inductive: By varying the distance between a toothed crown and the permanent magnet of the sensor, an electrical signal of the sine wave type is generated (Verified with scanner or oscilloscope equipment). These sensors do not require power and their resistance can be checked by a multimeter;
  
  
• Hall: The signal is generated by means of a magnetic flux variation in the sensing element. Its wave is of the square type (also checked with scanner or oscilloscope equipment). These sensors need an external power supply, which can be 5 or 12 volts. In the most modern vehicles, the magnetic crown is installed on the wheel bearings, that have mounting side.

According to Mori, If a sensor problem occurs, The system is disabled and the brake no longer has electronic help - which can lead to wheel locking. "The sensor has a auto-check which checks the health status of the system. In the face of any setback, The malfunction indicator light will illuminate on the panel. In that case, It is critical to avoid using the vehicle and take it for maintenance urgently."
