Product Description

The Allen-Bradley 42MRU-5000 is a modular photoelectric sensor that primarily operates in retroreflective mode. This means it detects an object when it interrupts a light beam that is reflected from a reflector back to the sensor. The Series 5000 is known for its modular design, consisting of a photohead (which houses most of the electronics) and a power base. This design allows for quick and easy replacement of the photohead without disturbing wiring or alignment, offering flexibility for various applications or sensing modes within the same power base. The “Green Line” designation often refers to a specific sub-series or feature set within the Photoswitch 5000 family, emphasizing its standard retroreflective capabilities.

Product Advantages

The 42MRU-5000 offers several key advantages for industrial automation:

• Modular Design: The separation of the photohead and power base simplifies installation, maintenance, and allows for quick sensor replacement or changing sensing modes without rewiring or realignment. This significantly reduces downtime.
• Universal Voltage Input: Its ability to accept a wide range of AC and DC voltages makes it highly versatile and adaptable to different power supply configurations.
• Robust Construction: With an IP66 enclosure rating and resistance to shock and vibration, it’s designed to withstand harsh industrial environments, including washdown applications.
• Reliable Detection: Infrared sensing and retroreflective mode provide reliable detection of opaque objects.
• Fast Response Time: The 1 ms response time is suitable for high-speed applications, ensuring accurate object detection.
• Flexible Output Options: Available with NPN/PNP solid-state or relay outputs, allowing compatibility with various control systems.
• Visible Status Indicators: Often includes highly visible LED indicators for power and output status, aiding in troubleshooting and setup.

Precautions

When installing, operating, or maintaining the 42MRU-5000, consider the following:

• Power Supply: Ensure the correct voltage and current are supplied to the power base, within the specified limits. Incorrect power can damage the sensor.
• Reflector Placement: For retroreflective sensors, proper alignment and placement of the reflector are critical for reliable operation. Ensure the reflector is clean and free from obstructions.
• Environmental Conditions: While robust, avoid exposing the sensor to extreme temperatures beyond its rated limits, corrosive chemicals, or direct impact that could damage the housing or optics.
• Electrical Noise: Protect sensor wiring from strong electrical noise sources (e.g., motor drives, welders) by using shielded cables and proper grounding practices to prevent false triggering.
• Mounting: Securely mount the sensor to prevent movement or vibration that could affect sensing accuracy. Ensure adequate space around the sensor for heat dissipation if applicable, and for easy access for maintenance.
• Cleaning: Regularly clean the sensor’s lens and the reflector surface to ensure optimal performance, especially in dusty or dirty environments. Use appropriate cleaning agents that won’t scratch or damage the optics.
• Safety: Always follow lockout/tagout procedures before performing any maintenance or wiring to prevent accidental startup or electrical shock.

Product Applications

The Allen-Bradley 42MRU-5000 photoelectric sensor is suitable for a wide range of industrial detection tasks, including but not limited to:

• Conveyor Systems: Detecting the presence or absence of products on a conveyor belt, counting items, or ensuring proper spacing.
• Packaging Machinery: Verifying product placement, lid detection, or ensuring proper package orientation.
• Material Handling: Sensing the position of pallets, boxes, or other materials in automated storage and retrieval systems.
• Automated Assembly Lines: Confirming component presence, tool position, or part alignment.
• Door and Gate Control: Sensing the presence of vehicles or personnel for automatic door or gate operation.
• Process Control: Monitoring levels in tanks, detecting jams in chutes, or confirming flow in certain applications.
• General Object Detection: Any application requiring reliable, non-contact detection of opaque objects across a moderate distance.
