Compact SICK UM18-217161101 ultrasonic sensor for precise short-range distance measurement. Fast, reliable detection for automation and industrial machines.
The SICK UM18-217161101 ultrasonic distance sensor provides dependable short-range measurement for applications that require stable object detection regardless of color, surface finish, or ambient lighting. It operates within a compact M18 cylindrical housing and delivers accurate readings from 20 mm to 150 mm, making it ideal for machines with limited mounting space. The sensor responds quickly with a 32 ms reaction time and maintains consistent accuracy in harsh industrial environments thanks to its IP65/IP67 protection rating. This model is well-suited for packaging, logistics, assembly automation, and general-purpose detection tasks where reliability and ease of integration are essential.
The UM18-217161101 enhances process stability by offering high repeatability, fine measurement resolution, and multiple switching modes for flexible configuration. Its Teach-in setup allows operators to adjust detection points directly on the device without additional tools, reducing commissioning time. The lightweight housing and M12 4-pin connector make installation simple in both new and existing systems. Designed to operate from –25°C to +70°C, the sensor maintains reliable performance even in demanding industrial conditions. Whether checking presence, monitoring levels, or positioning components, it provides long-term accuracy while minimizing maintenance efforts and downtime.
The UM18-217161101 stands out because it delivers precise, short-range ultrasonic detection in one of the smallest and toughest housings in its class. It combines fast response, stable measurement, and simple Teach-in configuration, making it a smart choice for engineers who want reliable performance without complicated setup. Its durability and consistency make it a sensor you can install once and trust for years.
This sensor solves the challenge of detecting objects that optical sensors struggle with—such as dark, shiny, transparent, or irregular surfaces. It ensures accurate distance measurement even in dusty, humid, or variable lighting conditions. When production lines demand consistent detection regardless of material or environment, the UM18-217161101 delivers steady results and minimizes downtime caused by unreliable sensing.

On automated wrapping machines, transparent films frequently cause missed detections when optical sensors are used. The UM18-217161101 avoids this issue by using ultrasonic measurement that reacts to the film’s physical presence instead of its appearance. Its short sensing range and quick response allow the controller to verify film alignment before sealing begins. This helps prevent open packages, reduces rework, and keeps production running consistently even when operators switch between glossy, matte, or fully transparent wrapping materials.
Factories with grinding, cutting, or sanding processes often produce airborne particles that settle on sensors, making visual detection unreliable. The UM18-217161101 continues to perform accurately because dust does not interfere with ultrasonic waves. Mounted above a conveyor, it confirms whether an item has reached the inspection point before the next mechanical step. Its durable IP-rated housing withstands heavy dust buildup, and its stable measurement range helps avoid false triggers caused by lighting changes, vibration, or surface debris.
Small jars, vials, or cups on a filling line require quick-level confirmation before entering the sealing station. The UM18-217161101 provides a non-contact way to verify liquid height without touching the product or being affected by color or clarity. Set in window mode, it checks that the level falls within a narrow acceptable range. This prevents underfilled or overfilled units from moving forward, reduces product waste, and supports consistent packaging quality — especially useful in food, cosmetics, and specialty chemical lines with frequent recipe changes.
In electronics assembly or precision handling tasks, robots must ensure a part is properly gripped before moving. The UM18-217161101 can be positioned near the gripper to confirm the presence and approximate height of small components. Its fine resolution and fast update rate detect irregular or missing parts quickly, allowing the robot to stop before placing something incorrectly. This minimizes production errors, protects delicate tooling, and improves overall process reliability without requiring additional cameras or complex sensing setups.
