B Code 5Pin Profibus M12 Terminal Resistance Connector

When transmitting high-frequency signals, the wavelength of the signal is shorter than that of the connection cable, and the signal will form a reflected wave at the end of the connection cable, which will interfere with the original signal. Therefore, it is necessary to install terminal resistors M12 and 7/8 at the end of the transmission cable so that the signal does not reflect after reaching the end of the transmission connection cable.

Fieldbus terminal resistor functions :

1. Improve the anti-interference ability, let the high-frequency and low-energy signals go away quickly
2. Ensure that the bus enters the recessive state quickly, so that the energy of the parasitic capacitance can go away faster;
3. To improve the signal quality, place it at both ends of the bus to reduce the reflected energy.
