IR distance sensor 1–25 mm 3Dsimo DDE1090

The 3Dsimo IR distance sensor 1–25 mm (model DDE1090) is a wired infrared proximity sensor designed for compact short-range distance detection. It measures object presence and approximate distance within a millimetre-scale range using infrared reflection, providing a simple sensing solution for close-proximity applications. The sensor's detection span of 1–25 mm makes it suitable where precise short-distance feedback is required and where space constraints demand a small form factor.

Advantages

This wired IR distance sensor delivers reliable short-range detection with fast response and low power consumption. Its compact design allows integration into tool heads, robots, and small automation systems without adding significant bulk. Infrared-based sensing reduces complexity compared with larger optical rangefinders and is effective for detecting opaque and reflective surfaces at close distances. The sensor's millimetre-scale range supports fine proximity control and collision avoidance in constrained environments.

Suitable for

• Robotics: end-effectors and obstacle detection for small robots
• Small automation projects requiring close-range presence sensing
• Tool heads and add-on modules where compact proximity feedback is needed
• Collision avoidance and safety interlocks for confined mechanisms

Key specifications

• Detection range: 1–25 mm
• Sensing technology: infrared reflection
• Connection: wired interface for direct integration
• Target type: effective on opaque and reflective surfaces at short distances
• Size: compact form factor suitable for tight assemblies

How to use

Mount the sensor so its sensing window faces the target area and ensure a stable mechanical fixation to avoid misreadings due to vibration. Connect the wired interface to the host controller or signal processing circuit following the manufacturer's connection scheme. Calibrate or verify readings by approaching known reference targets within the 1–25 mm range to confirm response and adjust any software thresholds. Maintain a clear optical path and avoid obstructing the sensor aperture for consistent measurements.

Usage recommendations

For best performance, use the sensor in environments with controlled ambient light and avoid directly exposing the sensing window to strong infrared sources. Verify detection behaviour with representative target materials and, if necessary, implement debounce or averaging in software to reduce the effect of transient reflections.
