Product Overview
The MicroE MII5750‑AB‑4000‑5‑1‑0 miniature optical encoder, part of Novanta’s Mercury II M5000 series, is a fully integrated digital incremental measurement head. It requires no external signal processing box, making it perfect for tight‑space precision platforms such as wafer‑inspection systems, micro‑positioning stages, and compact CNC machine tools.
Key Hardware Dimensions
- Read‑head size: 38.5 × 13.5 × 9.6 mm (thickness 39% less than competing units)
- Standard grating width: 6 mm (half the width of traditional gratings)
- Metal‑band thickness: 0.3 mm, cut‑to‑length on site, up to 30 m travel
- Glass grating range: up to 995 mm
- Alignment tolerance: ±0.15 mm gap, X‑axis ±1°, Y/Z‑axis ±2°
- Double‑shielded cable: 4.2 mm outer diameter, 10 m length, 20 mm bend radius, 20 M flex cycles
Programmable Core Functions
All parameters are configured via the MicroE SmartPrecision II software and stored in non‑volatile memory. Key programmable features include:
- Interpolation factor: X4‑X16384, linear resolution 5 µm – 1.22 nm
- Output bandwidth: 0.098 M – 50 M orthogonal counts/s
- Low‑pass filter cut‑off: 0.01 kHz – 100 kHz
- Dual‑level optical limit signals with selectable polarity
- Automatic signal‑optimization calibration for offset and contamination correction
- Three‑state differential alarm output for fault diagnosis

Buying Guide and Applications
Selection Guide – Linear vs. Rotary Grating
When choosing a grating type, consider travel distance and measurement mode. Metal‑band gratings (MT series) are ideal for long‑stroke applications up to 30 m and offer cost advantages. Glass linear gratings (MIIL series) provide higher resolution for short‑range tasks such as wafer‑stage positioning. Rotary circular gratings support precision turntables and spectrometers, allowing the same read‑head to serve both linear and angular tasks, simplifying system architecture.
Installation & Alignment Tips
The compact 9.6 mm height enables installation in confined chambers. Follow the ±0.15 mm gap tolerance and keep the X‑axis alignment within ±1°. The adhesive zero‑position marks can be placed anywhere on the scale, eliminating extra mechanical structures. Calibration typically completes within 30 seconds using the built‑in alignment routine.
Maintenance and Reliability
The encoder is solid‑state with no contact wear, guaranteeing a 5‑year stable operation under normal conditions. The double‑shielded cable prevents signal degradation over 10 m runs, and the built‑in self‑diagnostics monitor optical power and limit‑track reflectivity, instantly reporting anomalies to the controller.
Ordering and Inquiry Process
All units are stocked in the United States and shipped directly from the authorized distributor. Provide the exact model number MII5750‑AB‑4000‑5‑1‑0 and desired grating type when requesting a quote. For custom length metal‑band scales, specify the required travel distance; the distributor will cut and certify the scale on site.
Buyer FAQ
What measurement ranges does the MII5750‑AB‑4000‑5‑1‑0 support?
It supports metal‑band scales up to 30 m, glass linear gratings up to 995 mm, and circular rotary gratings up to 6000 rpm with nanometer resolution.
Can I use the same encoder for both linear and angular applications?
Yes. The single read‑head is compatible with linear metal‑band or glass scales and also with rotary circular gratings, allowing seamless switch between linear and angular measurement modes.
Is the encoder programmable on‑site?
All parameters are programmed through the MicroE SmartPrecision II software and saved in the head’s non‑volatile memory, so settings remain after power cycles.
What are the environmental standards?
The device complies with CE electromagnetic compatibility (EMC) requirements and is built for standard industrial environments.
How is the encoder calibrated?
Calibration is performed via the built‑in alignment routine; with the specified tolerances, alignment typically finishes in under 30 seconds.
Who should I contact for a quotation?
Reach out to Beijing High‑Control Technology Ltd., the authorized MicroE distributor, at 185‑1855‑6588 (Mr. Dong Yu).
