Autocollimation In the autocollimation concept, which uses only one optical lens,
the beam of light emitted by the sensor and the light beam
reflected by the reflector lie on a single optical axis. The emitted
light passes through a semi-transparent mirror before exiting the
optical unit. After being reflected by the reflector, the light beam
is diverted to the receiver with the aid of the same mirror. The
advantage is that, unlike with the dual lens concept, there is no
blind zone in front of the sensor.
BluePilot BluePilot refers to the adjustment and display elements of photo‐
electric sensors.
•
Photoelectric retro-reflective sensors and through-beam photo‐
electric sensors: Blue LEDs show the quality of alignment of
the light spot on the reflector or receiver.
•
Photoelectric proximity sensors: For these, BluePilot comprises
two elements: The Teach-Turn adjustment is used to set the
sensing range. The blue LEDs, in this case, show the configu‐
red sensing range (arranged in a semicircle around the Teach-
Turn adjustment).
•
Photoelectric sensors for detecting transparent objects: For
these, BluePilot comprises two elements: The Teach-Turn
adjustment is first used to select the operating mode (= ope‐
rating mode is displayed via the blue LEDs). The switching
threshold is adjusted by pressing the Teach-Turn adjustment.
IO-Link IO-Link is a non-proprietary internationally standardized communi‐
cation technology, which makes it possible to communicate with
sensors and actuators in industrial environments (IEC 61131-9).
IO-Link devices communicate with higher-level control systems via
an IO-Link master. The IO-Link devices are connected to these via
a point-to-point connection.
IO-Link enables communication between controllers, sensors and
actuators and allows the parameterization and reading-out of devi‐
ces to be centrally managed.
MultiMode
Response time The response time specifies the maximum amount of time that
elapses from when an event triggers the sensor to when a signal
is present at the output.
