Note:
Switching pressure specifications apply to vertical installation which is also the recommended posi-
tion with pressure-pipe connections pointing downwards. If the switches are installed horizontally with
AMP connection terminals uppermost, the switching values are approx. 20 Pa higher.
Pressure connections:
2 plastic pipe connection pieces
external diameter: 6.0 mm
Maximum operating pressure:
10 kPa for all pressure ranges
Mounting position
Switching pressure specifications apply to vertical installation which is also the recom-
mended position with pressure-pipe connections pointing downwards. If the switches are in-
stalled horizontally with AMP connection terminals uppermost, the switching values are ap-
prox. 20 Pa higher.
