The Y-Con®Jack-31, from Yamaichi, is a new RJ45 connector jack for PCB with integrated magnetic filter, and LED light pipes for the function display. The jack is particularly suited to industrial applications such as industrial Ethernet. The function principle of the integrated magnetic filter module definitely makes a decisive contribution to the signal conditioning, thanks to the galvanic separation (potential separation) and the additional components. Overlayed disruptions are thus effectively separated or faded out by the wanted signal. Current peaks, highly frequented overlays or electro smog can lead to malfunctions in the applications, particularly in an industrial environment. The 90°-angled jack for the THR PCB is also fitted with an all-round optimized EMC shielding made of nickel-plated brass. The two integrated light pipes on the left and right next to the mating face lead the light forwards onto each of the LED light sources mounted onto the PCB, hence emitting a function signal. The color selection is dependent only on the LED which is used, hence making the jack very flexible for all applications.
