Product Description
Capacitive sensor in thermo-
plastic polyester for mount-
ing in a 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 direct-
ly. Excellent for use in the
agricultural area (detection of
grains, fluids etc.).

Mode of Operation
VC11RTM24
(See operation
diagram). Power supply is
applied to the sensor (BN
and BU wires). When the
target is not present, the
relay operates (connection
between BK and YE wires)
and LED lights. When the
target is detected the time

applied to the sensor BN and

urement starts. When the
set time has expired (0-10
min.) the relay operates
(connection between BK
and YE wires) and remains
VC12RNM24
(See oper-
ation diagram). Power sup-
ply is applied to the sensor
(BN and BU wires). The
relay operates (connection
between BK and YE wires)
and remains ON until the
measurement starts and LED
flashes. After expiration of
the set time (0-10 min.), the
relay releases (connection
between BK and GY wires)
and LED turns off. The relay
remains released as long as
the target is detected.
