Unlock Precision Automation: The MRR1 Ultrasonic Sensor Solution

The MRR1 is designed for versatility and durability, packing high-end performance into a compact industrial housing. Built upon advanced PZT piezoelectric technology, this sensor represents the pinnacle of ultrasonic sensing innovation.

1. Superior Resolution with 200kHz Technology

Unlike standard 40kHz sensors that cast a wide, clumsy net, the MRR1 operates at a high frequency of 200kHz. This higher frequency generates a shorter wavelength, allowing the sensor to detect smaller objects and resolve finer details with millimeter-level precision.

• Repeatability: Listed ±0.1% of full scale; verify variant and test conditions
• Resolution: Up to 0.11mm at maximum sensing range
• Blind Zone: Minimized to just 100mm, enabling effective measurement in tight spaces

This exceptional performance is achieved through carefully engineered piezoelectric ceramic elements that form the heart of every MRR1 sensor unit.

2. Uncompromising Durability (IP67)

Industrial environments are unforgiving. Dust, moisture, and washdowns are part of the daily routine. The MRR1 features a robust IP67-rated housing, ensuring it remains completely dust-tight and can withstand immersion in water. Whether mounted on a dusty agricultural hopper or a wet food processing line, the MRR1 performs without degradation.

This durability makes the MRR1 ideal for applications similar to those served by our industrial ultrasonic cleaning systems, where harsh conditions are the norm rather than the exception.

3. Smart Connectivity

Ready for modern integration, the MRR1 series offers versatile output options including UART TTL, ensuring seamless communication with microcontrollers, PLCs, and IoT gateways. Its fast response time (approx. 125ms) makes it ideal for real-time monitoring applications where every millisecond counts.

Key Applications: Where the MRR1 Excels

Transparent Object Detection

One of the greatest challenges in packaging and manufacturing is detecting clear materials. Glass bottles, PET plastic trays, and clear protective films are invisible to many photoelectric sensors. The MRR1 solves this physics problem effortlessly.

Sound waves reflect off solid surfaces regardless of optical transparency, making the MRR1 the common choice for clear film detection and glass bottle counting on high-speed lines. This capability complements our acoustic transducer solutions designed for specialized detection applications.

Non-Contact Liquid Level Monitoring

For small tanks, medical reservoirs, or chemical dosing systems, contact sensors pose a risk of contamination and corrosion. The MRR1 provides a non-contact solution, measuring the level of liquids—from water to corrosive acids—without ever touching the surface.

With a sensing range of 100mm to 1000mm, it is perfectly sized for header tanks and dosing vessels. For specialized liquid detection needs, explore our flow measurement solutions and bubble sensor selection guide.

Robot Navigation and Collision Avoidance

Autonomous Mobile Robots (AMRs) and AGVs require reliable near-field detection to navigate warehouses safely. The MRR1's compact form factor and high-resolution "short-range" detection make it an excellent virtual bumper, detecting obstacles that might be missed by long-range LiDAR, ensuring smooth and appropriate autonomous operation.

Understanding how piezoelectric sensors compare to traditional sensing methods helps engineers select the optimal solution for robotic applications.

The Yujie Difference: Engineered Customization

When you choose the MRR1, you are not just buying a component; you are leveraging nearly three decades of material science expertise. Since 1996, Yujie Piezoelectric Technology has specialized in the formulation and manufacturing of piezoelectric ceramics.

Unlike assemblers who rely on generic off-the-shelf components, we manufacture the core piezoelectric elements inside the MRR1 ourselves. This vertical integration allows us to strictly control the resonant frequency and sensitivity of every unit.

Furthermore, our OEM/ODM capabilities mean we can tailor the MRR1 architecture—adjusting beam angles, housing materials, or connector types—to fit your specific machine design. Learn more about the strategic advantages of partnering with an OEM piezoelectric manufacturer.
