Product Features
Senses a wide range of materials
Suitable for dusty/dirty environments
Rugged enclosure protected to IP67
Mounts with a standard PG36 gland
Isolated changeover relay contacts
5 Amp rated relay contacts
24Vac/dc, 110Vac or 230Vac powered
Available with or without time delay
a distance of up to 25mm depending on material being sensed, with
the output relay energising upon detection. They have a high hysteresis,
adjustable low sensitivity and are sealed to IP67, making them ideal for
operation in dusty or dirty environments.
The PXW-3 has a built in time delay, adjustable from 4 seconds to 10
minutes, which is useful in tank filling applications to avoid frequent pump
motor restarts. They are available in 24Vac/dc, 110Vac and 230Vac
versions and have a fully isolated 5 Amp rated single pole changeover
relay output contact and an LED to indicate relay status.
