Note
1. The flow path inlet and outlet ports conform to P14-type female
quick-connect joints.
(The tube inlet and outlet ports have the same shape.)
* P14 is the number of an O-ring specified in JIS B 2401.
* The O-ring groove in the male joint must conform to P14 in JIS B 2406.
Note
2. To mount the Sensor
with
2.6-dia. holes,
use
P-type self-tapping screws
with
a nominal diameter of 3 mm and tighten them to a torque of 1.2
N·m
max.
The screw threads must engage for 5.5 mm min.
