SICK SureSense-HTF18, Operating Instructions Manual

Page: 3 / 58

Example: x = 150 mm, y = 15 => 15% of 150 mm = 22.5 mm. That is, the distance
between the object and the background must be at least 122.5 mm.

2 Mount the sensor using a suitable mounting bracket (see the SICK range of acces‐
sories).
Note the sensor's maximum permissible tightening torque of 0.56 Nm.
Note the preferred direction of the object relative to the sensor [see A].
3 The sensors must be connected in a voltage-free state (U
v
= 0 V). The information
in the graphics [B] must be observed, depending on the connection type:
–
Male connector connection: pin assignment
– Cable: core color
Only apply voltage/switch on the power supply (U
v
> 0 V) once all electrical connec‐
tions have been established. The green LED indicator on the top of the sensor
lights up.
Explanations of the connection diagram (Graphic B):
Switching outputs Q and /Q (according to Graphic B):
Switching output Q (according to Graphic B):
HTF18-P (PNP: load -> M)
HTF18-N (NPN: load -> L+)
L = light switching
D = dark switching
Alarm / Health = diagnostics output (see Additional functions)
4 Align the sensor with a fixed background. You must ensure that the optical opening
(front screen) of the sensor is completely clear [see Graphic E/F].
