Description
Product Name: 42GRR-9002 Allen Braley Central control module
Product details:
The Allen-Bradley 42GRR-9002 is a high-performance, general-purpose photoelectric sensor within the 9000 Series (specifically the Photoswitch family). It is designed for industrial environments where durability and long-range sensing are required.
Product Overview
The 42GRR-9002 is a Polarized Retroreflective Sensor. It functions by emitting a light beam to a reflector; the sensor then detects the beam as it returns. The “polarized” feature is crucial because it allows the sensor to ignore “false trips” caused by shiny objects (like a stainless steel can or shrink-wrapped pallet), as it only reacts to the light specifically de-polarized by the reflector.
Technical Specifications
Below are the key technical parameters for the 42GRR-9002:
Key Advantages
- Rugged Construction: Features a high-impact, chemical-resistant housing. It is built to withstand heavy washdown environments (IP69K rating).
- False-Trigger Prevention: The polarized filter ensures it doesn’t get confused by highly reflective surfaces that are not the intended reflector.
- Visible Alignment: The visible red beam makes it much easier for maintenance teams to align the sensor with the reflector during installation.
- Diagnostics: Includes highly visible LED indicators for “Power,” “Status,” and “Margin” (the margin indicator flashes if the lens is getting dirty or the alignment is drifting).
Important Considerations (Usage Notes)
- Reflector Quality: The sensing distance is highly dependent on the quality and size of the reflector used. Ensure you use a high-quality corner-cube reflector for maximum range.
- Alignment: While the red beam is visible, precise alignment is necessary for the “Margin” indicator to stay solid, ensuring long-term reliability.
- Lens Maintenance: In dusty or oily environments, wipe the lens periodically with a soft, damp cloth. Avoid using harsh abrasive cleaners that could scratch the plastic lens.
- Wiring: Always ensure the power is off before connecting the M12 quick-disconnect cable to prevent accidental short-circuiting of the NPN/PNP outputs.
Product Applications
The 42GRR-9002 is a “workhorse” sensor commonly found in:
- Conveyor Systems: Detecting the presence or absence of boxes, even those with glossy tape or plastic wrapping.
- Packaging Machinery: Counting items on a high-speed line.
- Food and Beverage: Because of the IP69K washdown rating, it is ideal for bottling lines and food processing.
- Material Handling: Pallet detection in automated warehouses.
