Mechanical drawing / connection
ES 50 K
- LM = 140mm
- Lt = 159mm
For measurements with plus/minus range, the sensor must be preloaded so that the output dimension is Lm + 25mm = 165mm.
Connection
Standard: 3m cable, 4-wire, shielded
Cable lengths of more than 100m are possible by using special low-impedance cable.
