In industrial automation and optical detection, reflectors play a crucial role. They ensure the precise operation of sensors, even in complex or demanding environments. The SICK brand offers a wide range suitable for various applications: from standard models to more specialised ones.
Here is a comprehensive guide to understanding the types of SICK reflectors, common usage errors, and how to choose the most suitable model.
Standard Reflectors
The standard reflectors are intended for general applications. Easy to install, they offer excellent value for money and are suitable for short to medium-range sensors.
Examples of SICK models:
- PL50A Rectangular, screw-mounted, flat 48 mm, RoHS compliant
- PL30A Rectangular, to be screwed
- PL51A Rectangular sticker, key width 48 mm, RoHS compliant
- PL22-1 Round, clip-on, plug-in
- C110A Round, screw-on, diameter 84 mm, compliant with RoHS
Frequent misuse:
- Incorrect assembly or orientation not suitable for the sensor beam
- Insufficient cleaning of reflective surfaces, reducing accuracy
- Use in overly aggressive environments without protection
Special Reflectors
For extreme environments or specific uses, these reflectors have unique properties, such as resistance to chemicals, heat, or moisture.
Examples of SICK models:
- FLV-PL50 Counter-flange for dust protection tubes
- SW50 High temperature, glass, screw-on
- PL53A Oil-resistant, solvent-resistant
- PL50HS Adjustable heating for temperatures < 15 °C
- PLV14-A Stainless steel, IP 69K, hygienic design
Frequent misuse:
- Choose a standard reflector for extreme conditions, causing rapid failure
- Installation without compliance with IP standards or chemical protection
- Neglecting the needs for regular cleaning or maintenance
Micro-Prism Reflectors
These reflectors provide precise and directional reflection, ideal for laser sensors and critical measurements.
Examples of SICK models:
- PL23FT Sticker, 20 mm x 40 mm
- PL23FB To be screwed, 20 mm x 40 mm
- PL20FS01 Small retroreflective device with black rear cover
Frequent misuse:
- Incorrect orientation, leading to inaccurate measurements
- Deposit of dust or oil on the reflective surface
- Use for measurements beyond the recommended range
Reflective Strips
To mark large areas or secure zones, reflective strips are ideal. They ensure maximum visibility and durable signage.
Examples of SICK models:
- Bande réfléchissante 2 x 1,2 m Sticker, field coverage 1.2 m x 1.2 m
- REF-AC1000-73P01 Suitable for laser sensors, self-adhesive, cuttable
- REF-DG-K Film "Diamond Grade", sticker, custom-made
Frequent misuse:
- Misalignment with the sensors
- Use on dirty or unsuitable surfaces
- Choice of material not suitable for the application (e.g. standard tape instead of Diamond Grade for critical areas)
Choosing the right reflector depends on the application, the environment, and the type of sensor used. Misuse or an inappropriate choice can quickly lead to costly production downtime.
This is where SOSMachine comes in. With our expertise in industrial maintenance and management of critical parts, we help manufacturers to:
- Select the appropriate reflector for each sensor and environment
- Monitor the condition of the components to anticipate their replacement
- Reduce unplanned downtime and optimise operating time
By combining the quality of SICK products and our connected solution, SOSMachine transforms industrial maintenance into an intelligent, safe, and cost-effective process.
