Hi,

I have a rotary encoder (G58 LS LD BI) I'm wiring into a new machine. Forgetting the differential outputs it has the following pins meant for the power supply:

vcc
0v
vcc sense
0v sense

The power supply itself does not have sense lines.

Can I simply tie the 'vcc' & 'vcc sense' lines together and connect to +5v? Then tie the '0v' & '0v sense' lines together and connect to 0v? I'm not fused about the sensing lines for voltage drop, I just need power to the encoder.

Datasheet attached for encoder.

Thanks

 

Actually on the transducer the Vcc & Vcc Sense as well as the 0V and 0V Sense are likely internally joined. I doubt you need to jumper them but have at it.

In a word, yes.

Are you actually using the sense lines?
If not there is no need to connect them usually.
Max.

Hi Ron,

Can you please explain what are these sense pin for? My encoder also has these power sense pin but I didn't connect them together. What will happen should the sense aren't connected internally?

Thanks.

Sure, we can do that. The sense lines are generally used with power supplies having sense terminals at their outputs. This comes in extremely handy when long distances exist between the supply/indicator and the encoder/sensor. The idea is to eliminate I * R loss in a long cable run and make sure the desired excitation/operating voltage at the device is what it should be.

Your linked data sheet, page 4 they call out the pins or wires on the connector. You will find VCC and VCC Sense as well as 0 Volts and 0 Volts Sense are likely tied together. Again, this is for when using power sources which use sense leads for long cable runs. So unless you have a long cable run and a power source which uses external sense don't worry about it.
