When noise is conducted to the cable, strong noise is radiated from the cable. Therefore, the BLM Series (Chip Ferrite Bead) is installed on the cable connection.

Since sensor input signals for detecting the presence or absence of paper are of a low speed and temporary, an EMI filter whose impedance value is as large as possible should be used.

When the noise level is high, a capacitor is installed in combination with the EMI filter.
