3.2 Function
The proximity sensor SDBT­MSX detects the magnetic field of the piston magnet.
In the sensing range of the proximity switch, a switching point can be pro­
grammed. To set a switching point in the sensing range of the proximity sensor,
there are two options:
– Auto teach­in
– Capacitive operating key

4.1 Electrical
WARNING!
Risk of injury due to electric shock.
• For the electrical power supply, use only PELV circuits in accordance with IEC
60204­1/EN 60204­1 (Protective Extra­Low Voltage, PELV).
• Observe the general requirements of IEC 60204­1/EN60204­1 for PELV cir­
cuits.
• Only use voltage sources that ensure a reliable electric separation from the
mains network in accordance with IEC 60204­1/EN 60204­1.

4.2 Mechanical
• Mount the proximity sensor in the end position of the piston so that the end
position is in the sensing range of the sensor. If available, the orientation aid
provides the marking of the piston end position on the drive.
