Product description
3.1 IN4000 Standard series safety
switches
The IN4000 Standard series safety switches all use
the same principle of operation, but differ in design,
installation, response range and classification.
The IN40-D0101K safety switch has a square housing
with a sensing face that can be aligned. The sensor
can also be installed flush or flush on one side, except
in steel.
The IN40-D0303K and IN40-D0202K safety switches
are fitted in a cylindrical housing and are not suitable
for flush installation or installation flush on one side.
The IN40-D0304K safety switch is manufactured in a
cylindrical housing and is suitable for flush installa-
tion.

Features and principle of operation

The IN4000 Standard series safety switches are
typically used for safe position detection, as is the
case, e.g., when monitoring a movable guard. The
sensor detects the presence or absence of metal. To
address requirements to prevent simple tampering,
the switching range of the sensor is monitored
spatially and over time.
Using LEDs the status can be read directly on the
sensor or the protective device. Errors, for example a
coil break, short-circuit or cable break are detected by
the sensor's self-monitoring.
The safety switch can be connected directly to a safe
PLC or a SICK evaluation unit, e.g. Flexi Classic or Flexi
Soft.
