Product Description
Ordering Key
VC11RT12010M
Capacitive sensor in thermo-
plastic polyester for mount-
ing in PG 36 screw gland.
Available with adjustable
sensing distance and with/-
without built-in time delay
(ON or OFF delay). The relay
output ensures that the load
can be driven directly. Ex-
cellent for use in the agricul-
ture area (detection of grains,
fluids etc.).

Mode of Operation
VC11RT (See operation dia-
gram). Power supply is
applied to the sensor (brown
and blue cables). When sen-
sor is not activated, the relay
operates (connection be-
tween black and yellow
cables) and LED lights.
When sensor is activated the
time measurement starts
and LED flashes. After expi-
ration of the set time (0-10
min.), the relay releases
(connection between black
and grey cables) and LED
turns off. The relay remains
released until sensor is acti-
vated again.
VC12RN (See operation dia-
gram). Power supply is
applied to the sensor (brown
and blue cables). The relay
operates (connection be-
tween black and yellow
cables) and remains ON until
the sensor is activated. After
activation of the sensor the
relay releases (connection
between black and grey
cables.)
VC12RT (See operation dia-
gram). Power supply is
applied to the sensor (brown
and blue cables) and time
measurement starts. When
the set time has expired (0-
10 min.) the relay operates
(connection between black
and yellow cable) and
remains connected until the
sensor is activated. After
activation of the sensor the
relay releases (connection
between black and grey
cable). As soon as the sen-
sor is unactivated again the
time measurements of the
set time starts.
