Mechanical drawing / connection
ES 20 K
- LM = 97mm
- Lt = 116mm
For measurements with plus/minus range, the sensor must be preloaded so that the output dimension is Lm + 10mm = 107mm.
Connection
Standard: 3m cable, 4-wire, unshielded
Cable lengths of more than 100m are possible by using special low-impedance cable.
