Product description
3.1 Safety switch of the IN4000 Direct
series
The safety switch has a square housing with a sensing
face that can be aligned. The classification as per
EN 60 947-5-2 depends on the mounting method (see
Tab. 5 on page 68).
3.2 Features and principle of
operation
The safety switches of the IN4000 Direct series are
typically used for safe position detection. 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 sen-
sor. 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 fail-
safe PLC or another safe evaluation unit.
