Installation Manual
5.2.2 Cylinders with integrated sensors and Temposonics
®
M12 connector system
When using dry or powder painting methods for cylinders, powder is applied to the component surface by means of static charge. These methods
employ very high voltages that can damage the electronics of Temposonics
®
position measuring systems integrated in the cylinders. This can be
prevented using the following metal protective caps.
The metal protective cap safeguards the contact pins and thus the electronics of the sensor against electrostatic effects (high voltage). It is impor-
tant to note that:
• The material of the protective cap must be permanently electrically conducting.
• The cap must not be of aluminum (aluminum is subject to oxidation and can cause electric isolation).
• The metal protective cap must have an M12x1 thread.
• The cap must be screwed up to the connector flange plate.
• Make sure that no paint particles contaminate the thread or the contact pins.
• The thread of the protective cap must be clean and free from paint particles and other substances at all times.
• The metal protective cap must be tightened only so that it is hand-tight (max 5 Nm).
• Paint particles on the cap outside are uncritical.
Drawing examples for the protective cap are given in the attachment.
5.2.3 Cylinders with integrated sensors and connecting cables or third-party connectors
Electrostatic painting cannot be used for sensors with connecting cables, since the cable cannot be protected safely against the high
process voltage. Safe electrostatic painting is ensured only in conjunction with the MTS M12 connector system and the brass caps shown
in chapter 7.6.
Suspended from the cylinder foot - no potential formation between
sensor housing and sensor connections
Suspended from the piston rod – high potential (high voltage) between
sensor housing and connecting cable possible
