SICK

SICK develops sensors for factory automation and machine safety: photoelectric sensors for non-contact object detection, proximity sensors for position sensing without contact, ultrasonic sensors for transparent or difficult-to-detect objects, and cylinder sensors for direct piston position sensing on pneumatic cylinders.

Had to replace a lamp, but the same was no longer available. Great advice, found a suitable replacement and delivered it quickly.

SICK Sensor Intelligence – Industrial Sensing

SICK AG was founded in 1946 in Waldkirch in the Black Forest and has grown into one of the world's leading manufacturers of industrial sensors. The "Sensor Intelligence" concept means sensors that do more than measure: they evaluate and process information directly in the sensor, reducing the load on higher-level controllers and speeding up response times in automated systems.

  Installer's tip: Choosing the right sensor type depends on the detection task. Through-beam sensors are the most reliable choice for highly reflective or transparent objects. Retroreflective sensors are easier to install since only one side needs wiring. Diffuse sensors need no reflector and work well in confined spaces. SICK offers a wide range for each type, in various sensing ranges and protection ratings.

SICK Products at WATT24

Through-beam sensors – separate transmitter and receiver for maximum detection reliability
Retroreflective sensors – transmitter and receiver in one housing, working with an opposing reflector
Diffuse sensors – non-contact object detection without a separate reflector
Proximity sensors – inductive sensors for metal detection and position sensing
Cylinder sensors – for direct piston position sensing on pneumatic cylinders
Ultrasonic sensors – for transparent, shiny or irregularly shaped objects
Reflectors & cable sockets – accessories for installation and connection

FAQ: SICK

What does SICK manufacture?

SICK AG is a German sensor manufacturer based in Waldkirch. The company develops sensors and sensor solutions for factory automation, logistics and process automation: photoelectric sensors, proximity sensors, ultrasonic sensors, cylinder sensors and other industrial sensing technology.

What is the difference between a through-beam sensor and a retroreflective sensor?

A through-beam sensor has separate transmitter and receiver units positioned opposite each other. An object is detected when it breaks the light beam. A retroreflective sensor houses transmitter and receiver in the same unit and uses an opposing reflector. It is simpler to wire since only one side needs a cable, but is more sensitive to highly reflective objects.

Where are SICK sensors used?

SICK sensors are used in factory automation, conveyor technology, packaging and intralogistics: wherever objects need to be reliably detected, counted or positioned without physical contact.

Which SICK products are available at WATT24?

WATT24 stocks SICK photoelectric sensors, proximity sensors, through-beam sensors, retroreflective sensors, diffuse sensors, cylinder sensors, ultrasonic sensors, reflectors and cable sockets.
