SICK 5304812 P250 reflector 47x47 mm 2-hole mounting content_copy

The SICK P250 is a rectangular standard reflector specifically developed for use with optical sensors and light barriers in industrial environments. It functions as a retroreflector, redirecting the light signal emitted by a transmitter back to the receiver to enable safe and reliable detection of objects or positions. The reflector is designed for screw-mounted installation and is made from a material blend of PMMA and ABS, offering high mechanical stability and weather resistance. The operating ambient temperature ranges from −30 °C to +65 °C, making it suitable for indoor and outdoor applications, provided the temperature limits are not exceeded.

Applications
The SICK P250 is used in industrial applications where optical feedback regarding the position or presence of an object is required. This includes, for example, automation systems in manufacturing, assembly lines, logistics, and material flow control. It is used in combination with SICK light barriers or sensors that operate on reflection principles. The rectangular shape and screw-mounting allow for flexible and stable installation on machines, conveyor belts, or other structured surfaces.

Functions and Features in Detail
The reflector operates based on the principle of light reflection: a transmitter in the sensor emits a light signal, which is reflected by the reflector and directed back to the receiver. If an object interrupts the light beam, the receiver is no longer reached, triggering a state change in the system. The reflector’s dimensions are 51.2 mm (width) × 8.2 mm (height) × 60.9 mm (length), enabling a compact design. Mounting is achieved via two holes designed for secure attachment to metallic or solid surfaces. The PMMA/ABS material ensures high light reflectivity and good mechanical strength against physical stress.

Technology Explained Simply
The reflector utilizes the properties of PMMA (polymethyl methacrylate) and ABS (acrylonitrile butadiene styrene) for optimal light reflection and resistance to mechanical and thermal stress. PMMA is known for its high light transmittance and reflectivity, while ABS provides impact resistance and dimensional stability. The combination of both materials ensures reliable performance even under frequent mechanical stress or in environments with temperature fluctuations. The operating temperature range of −30 °C to +65 °C covers most industrial applications, including climate-controlled halls and outdoor areas with mild temperatures.

Compatibility and Accessories
The SICK P250 is specifically designed for use with SICK sensors and light barriers that operate on reflection principles. It is not universally compatible with all brands and requires a matching transmitter-receiver combination from SICK. As an accessory, the XUZC50 universal reflector (50x50mm) is available, which can be used in similar applications but features a different shape and mounting method. The P250 is not interchangeable with the XUZC50, as the mounting holes and dimensions differ. No information is provided in the sources regarding additional compatible sensors or accessories.

Mounting and Installation
The reflector is mounted by screwing it onto a suitable surface. The two holes in the reflector allow for secure fastening using screws or bolts, although the exact hole size is not specified. The rectangular shape and low height of 8.2 mm ensure minimal space requirement and easy integration into existing machine structures. The mounting position must be chosen so that the sensor’s light beam can reach the reflector unobstructed and be reflected back. Precise alignment is necessary to ensure reliable signal return.

Operational Advantages
The SICK P250 offers high reliability in signal return, which is critical for the operation of safety and automation systems. The PMMA/ABS material combination ensures long service life and resistance to wear. The screw-mounting enables a stable and durable installation that remains secure even under vibration or mechanical stress. The operating temperature range of −30 °C to +65 °C expands its application to various industrial environments. The reflector does not include additional components such as batteries or cables; the delivery scope consists solely of the reflector itself.

Protection Rating and Environmental Conditions
The sources do not specify a protection rating (e.g., IP classification) for the reflector. However, the operating ambient temperature is defined, and the materials are designed for industrial conditions. No specific IP rating is mentioned, so no statement can be made regarding resistance to dust, water, or other external influences. Therefore, operating conditions should be chosen to ensure temperature limits are respected and to avoid direct mechanical damage or contamination of the reflector.
