A soluble screw locking adhesive should be used when installing the screws.
Alternatively, the flange plate can be fastened using DIN 6660 button-head rivets.
4.4.2
Installation using cable connector and screwed cable gland
For devices with a cable connection, a protection class rated (preferably IP68) metallic
cable gland should be used for sealing and strain relief. The cable glands should also
be protected against damage by surrounding them with metal profiles (e.g. U-steel).
When installing connector plugs on devices with a cable connector, please consider the
following:
•
Enclosure rating: (preferably IP68)
•
Connector housing:
Metal or impact-resistant plastic (check media resistance)
•
Protect against external influences: enclose the cable sheath and male connector
•
Prevent fluid ingress: the cable sheath should ideally be coated with sealing com‐
pound at offset locations
•
Polarity: ensure correct polarity
•
Male connector with screw terminals:
Apply ferrules and clamp all strands in the ferrule
•
Soldered connections: no projecting strands or “cold joints”
•
Crimp contacts: use a suitable tool to produce a gas tight crimp
•
ESD protection: protect workplaces and persons from electrostatic discharge
•
Prevent fluid ingress:
Use suitable caps to seal the male connector after installation
•
Screwed cable glands: protect by enclosing within steel profiles
4.5
Install the retaining screw
The retaining screw prevents the sensor housing from moving in the axial direction. A
DIN 913 M5x10 threaded pin with tapered head should be used for this purpose. Use a
soluble screw locking adhesive when installing the threaded pin.
NOTICE
Risk of damage to the device during installation.
The screw must only rest in the slot and not be tightened too hard.
b
Tighten the screws with a torque of 0.5 Nm ... 1.0 Nm.
4.6
Cylinder handling after sensor installation
4.6.1
Washing and drying the cylinder
To protect the connecting cable and male device connector from ingress of cleaning
agents, please observe the following:
Sensors with M12 connector system
•
Drying temperature: max. 90 °C
•
Pressure of the cleaning fluid:
≤
5 bar
•
Protective cap: use the supplied plastic protective cap
•
In case of higher pressures: use a metallic protector
•
Protection class: IP69K
