MOUNTING RECOMMENDATIONS
Make sure that the power cable for the detector is not
subject to tension or torsional stress throughout its
lifetime.
- Avoid using cables which are not long enough.
- Do not pull on the cables.
- Do not fold the cables.
- Observe a minimum bending radius of 15 mm in static
assembly.
- Do not pinch the cables when using
a retaining ring plier. The minimum
tightening torque must be observed
(for cable dia. 2 – 2.5 mm).
Flexible applications:
In dynamic assembly the cable is subject to oscillating
movements due to the weight of the connectors or
excess cable lengths which may cause the cable to
break. The connectors must therefore be connected to
the cylinder.
For cylinder + detector applications with long travels and large movements you
must use the mini-detector with M8 connector integrated in the housing (X)
and lead outlets equipped with a (2- or 3-wire) class 6 type cable (Y) especially
intended for this purpose.
- Connect the cable to the cylinder as shown opposite and observe a minimum
bending radius of 120 mm.
(X)
- Do not mount position detectors near to ferromagnetic or intense
electromagnetic fields (solenoid coil, soldering tongs etc.).
- Do not use the PVC cable in oily environments or with incompatible
solvents (consult us if necessary). Clean with an alcaline solution (soapy
water).
Assembly of detector with integrated connector:
- Tighten the connector by hand (do not use any tools).
PUTTING INTO SERVICE
- Observe the maximum/minimum (electrical, mechanical,
temperature) operating ranges defined for the UNI detectors in
this documentation. Any non-compliance may cause the detectors
to deteriorate.
- All modifications to the equipment shall be subject to the prior
approval of ASCO/JOUCOMATIC.

MOUNTING ON ISOCLAIR CYLINDER Ø 8 to 63:
1 - Put the detector in place, on collar
2 - Introduce the screw into the detector and tighten the unit.
3 - Open the collar.
4 - Place the unit detector + collar around the barrel.
5 - Position the detector + collar unit at the desired point of detection.
6 - Tighten the unit on the cylinder.
It is possible to mount additional magnetic detectors

III
the detectors with integrated male connectors must be mounted
with the connectors facing towards the centre of the cylinder.
MOUNTING ON PES CYLINDER WITH

PROFILED BARREL Ø 32 to 125:
1- Put the detector in place, on the mounting kit
2- Introduce the screw into the detector and tighten the unit.
3- Place the unit on one of the bosses and position it at the
desired point of detection.
4- Make sure that the detector is in contact with the barrel and
tighten the unit on the cylinder (use a 2 mm hexagon wrench).

TIE RODS
Ø 32 to 80 mm :
1- Put the detector in place, on the mounting kit
2- Introduce the screw into the detector and tighten the unit.
3- Place the unit on one of the tie rods and position it at the
desired point of detection.
4- Make sure that the detector is in contact with the barrel and
tighten the unit on the cylinder (use a 3 mm hexagon wrench).
Ø 100 à 200 mm :
1- Place the collar around the barrel (underneath the tie rods).
Position the 2 ends towards the fastening side.
2- Loosen the flange so that you have enough allowance for
tightening (do not remove the screw from the support).
3- Place the detector on its plastic support.
4- Introduce the screw into the support and tighten the unit.
5- Introduce the collar ends into the flange openings.
6- Slip the detector together with its support underneath the
collar.
7- Position the detector + collar unit at the desired point of
detection.
8- Make sure that the detector is in contact with the barrel and
tighten the unit on the cylinder.

V
In order to fasten the detector on cylinder diameters 100 to
200 mm with its electrical outlet to the rear, rotate the sup-
port + detector by 180° after having loosened the collar (do
not remove it).
