Description

The MD17/73 operates on the thru-beam (opposed) photoelectric principle, where an infrared transmitter and receiver are separated. The modulated 950nm light beam provides immunity to ambient light interference up to 10,000 lux, ensuring reliable object detection even in variable lighting conditions. The sensor’s fast response time (≤3 ms) and 150 Hz switching frequency enable high-speed counting and positioning tasks on fast-moving production lines.

Engineered for industrial durability, the sensor features a robust ABS housing with an IP67 rating, making it resistant to dust ingress and temporary water immersion. It includes built-in protection against short-circuits and reverse polarity, safeguarding both the sensor and the connected control system. The compact design and dual mounting options (M18 threaded front or side) offer flexible integration into machinery, conveyor systems, and automated handling equipment.

Key Features

  • Long-Range Infrared Sensing: Modulated 950nm LED provides a stable, long-distance detection beam up to 15 meters.
  • Industrial Environmental Protection: IP67-rated enclosure ensures reliable performance in dusty, damp, or washdown industrial settings.
  • Fast & Reliable Switching: High 150 Hz switching frequency and ≤3 ms response time for high-speed automation applications.
  • Robust Electrical Design: Features short-circuit and reverse polarity protection for enhanced system safety and longevity.
  • Clear Operational Feedback: 360° visible LED indicators provide instant visual confirmation of power and output status.
  • Versatile Mounting: Compact miniature housing supports both M18 threaded front mounting and side mounting for flexible installation.
  • Wide Voltage Compatibility: Operates from 10-30V DC, compatible with standard industrial 24V DC power supplies.
  • High Ambient Light Immunity: Functions reliably in ambient light conditions up to 10,000 lux.

Applications

  • Conveyor Belt Object Detection: Counting, positioning, or jam detection of products on high-speed packaging and material handling lines.
  • Automated Storage & Retrieval Systems (AS/RS): Verifying the presence or absence of pallets, totes, or containers over long aisles.
  • Machine Guarding & Safety: Creating non-contact safety light curtains or presence detection zones for personnel and equipment.
  • Logistics & Sorting Systems: Detecting parcels and packages on roller conveyors for routing and dimensioning.
  • Industrial Door & Gate Control: Sensing vehicle or personnel approach for automatic door opening and closing sequences.

Frequently Asked Questions

What is the operating voltage range for the Pepperl+Fuchs MD17/73 sensor?

The MD17/73 operates on a wide-range DC supply from 10 to 30 volts. This makes it directly compatible with standard industrial 24V DC power systems. The sensor includes reverse polarity protection to prevent damage from incorrect wiring.

How does the thru-beam detection work, and what is the maximum sensing distance?

This is a thru-beam (opposed) sensor, meaning it requires a separate transmitter (this unit) and a receiver unit aligned opposite each other. An object is detected when it breaks the modulated infrared beam. The maximum effective sensing range between the aligned transmitter and receiver is 15 meters under optimal conditions.

What does the IP67 protection rating mean for this sensor?

An IP67 rating indicates the sensor is completely dust-tight (IP6X) and can withstand temporary immersion in water up to 1 meter deep for 30 minutes (IPX7). This makes it suitable for harsh industrial environments, including washdown areas, where exposure to dust and water sprays is common.

Can this sensor be used in high ambient light areas?

Yes, the modulated 950nm infrared light source provides high immunity to ambient light. The sensor is specified to operate reliably in ambient light conditions up to 10,000 lux, which covers typical factory lighting, preventing false triggers from sunlight or bright lamps.

What are the mounting options for the MD17/73?

The sensor features a compact housing with an integrated M18 threaded barrel for standard front mounting. It also includes side mounting holes, offering flexibility for installation in space-constrained applications on machinery, frames, or conveyor supports.
