Long-Range Polarized Retroreflective Laser Sensors

TAKEX LD-MX5R laser photo sensors use coaxial polarized retroreflective optics for long-range, high-precision positioning and small-object detection.
The lineup offers NPN or PNP output, sensing up to 5 m with the K-7 reflector, Class 1 variants up to 3 m, laser emission inhibit input, and IP66 protection.

Features

Coaxial high-precision sensing: The emitter and receiver share a coaxial optical arrangement, supporting detection through narrow gaps or holes and accurate recognition of small positional differences.
Fine laser beam for small objects: The extra-fine laser beam is designed for minute-object detection and precise positioning.
Polarized retroreflective detection: Polarized retroreflective optics support detection of mirror-like objects and highly reflective workpieces.
Sensing up to 5 m: LD-MX5R and LD-MX5RPN reach up to 5 m with the K-7 reflector, while Class 1 models cover 0.3–3 m.
Interference prevention and emission inhibit: The series includes mutual interference prevention and a laser emission inhibit input for machine integration.

Specification notes

Detecting distance depends on the reflector: The 5 m maximum applies to standard models with the K-7 reflector. S-0503A, K-72, and K-71 provide different ranges.
Standard and C1 models differ in laser class and sensing range: C1 models are Class 1 variants and cover 0.3–3 m with the K-7 reflector.
The laser uses a slow-start circuit and turns on approximately one second after power-up or release of the emission inhibit input. Do not look directly into the laser beam or point it toward the human body.

FAQ

Q1: What is the TAKEX LD-MX5R?
A: The LD-MX5R is an embedded amplifier laser photo sensor using coaxial polarized retroreflective optics for long-range precision positioning and small-object detection.

Q2: What models are available?
A: The lineup includes LD-MX5R, LD-MX5RPN, LD-MX5R-C1, and LD-MX5RPN-C1.

Q3: What is the maximum sensing range?
A: LD-MX5R and LD-MX5RPN reach up to 5 m when used with the K-7 reflector.

Q4: What is the sensing range of the Class 1 models?
A: LD-MX5R-C1 and LD-MX5RPN-C1 cover 0.3–3 m with the K-7 reflector.

Q5: Can LD-MX5R detect mirror-like objects?
A: Yes. Its polarized retroreflective detection method is designed to support mirror-like workpieces.

Q6: Why is LD-MX5R suitable for narrow spaces?
A: Its coaxial emitter and receiver arrangement allows the fine laser beam to detect targets through narrow gaps and holes.

Q7: Are NPN and PNP outputs available?
A: Yes. LD-MX5R and LD-MX5R-C1 use NPN output, while LD-MX5RPN and LD-MX5RPN-C1 use PNP output.

Q8: Is Light-ON/Dark-ON operation selectable?
A: Yes. All four models support selectable Light-ON and Dark-ON operation.

Q9: Can laser emission be externally disabled?
A: Yes. A laser emission inhibit input is provided. After the inhibit condition is released, the slow-start circuit turns on the laser after approximately one second.

Q10: What applications are suitable for LD-MX5R?
A: Applications include semiconductor, LCD, precision machinery, electronic component, and automotive parts equipment, including detecting slightly lifted ICs in pallets.
