Output for encoder, GND

The differential inputs A/A, B/B and C/C are internally provided with a 120 Ohm termination resistor.

The differential signals are each expected with a 1 Vpp level with a 2.5 V averaged voltage relative to the encoder supply voltage (see chapter “Principle of the sine/cosine measurement”).

EL5021-00x0 - Connection 2:

Shielding

If the sensor has a shielded cable, the shield must be connected to an external earthing point. The EL5021 has no shield connection point.
