Product Overview
Designed for precision displacement detection in constrained spaces, Nisshinbo Micro Devices NJL 9101R integrates an optical emitter and photodetector onto a single compact substrate. Built in a low-profile 6-pad surface-mount package measuring roughly 2 mm across, this device enables non-contact motion tracking in tightly confined assemblies.
Key Features
- Miniature 6-pad surface-mount footprint
- Integrated optical emitter and photodetector array
- Reflective sensing configuration for non-contact position tracking
- Symmetrical bottom contact pads with central optical window
- Compact profile suitable for miniature motion mechanisms
Applications
- Precision lens position feedback and linear motion tracking in compact mechanisms.
- Micro-robotics displacement sensing and miniature rotary encoder assemblies on maker workbenches.
- Optical feedback sensing in space-restricted automated assemblies and instrumentation.
Frequently Asked Questions
How does a reflective optical position sensor operate?
It directs light toward a target surface or patterned scale and detects the reflected beam, translating physical displacement into electrical signals without mechanical friction or contact.
How is package orientation determined during installation?
The package geometry features a distinct optical trench and asymmetrical substrate markers to align pin orientation on the PCB footprint before reflow soldering.
Packed into a footprint smaller than a match head, this little sensor handles precision tracking where larger encoders simply cannot fit. Drop it onto your board and give your micro-mechanism an accurate sense of place.
