- Unified 6 mm wide scale, half the width of traditional gratings, saving installation space.
- Metal steel‑strip scale thickness 0.3 mm, cut‑to‑length on site, up to 30 m travel.
- Glass grating range up to 995 mm.
- Alignment tolerances: ±0.15 mm gap, X‑axis ±1°, Y/Z‑axis ±2°.
- Dual‑layer shielded cable, 4.2 mm diameter, 10 m length, 20 mm bend radius, 20 million cycles without signal loss.
Programmable Core Functions
All parameters are set via the MicroE SmartPrecision II software and stored in non‑volatile memory, surviving power‑off. Features include:
- Interpolation factor adjustable from 4 to 16 384, delivering linear resolution from 5 µm down to 1.22 nm.
- Output bandwidth 0.098 M to 50 M orthogonal counts/s, protecting controllers from overload.
- Low‑pass filter cutoff 0.01 kHz‑100 kHz, selectable per speed regime.
- Programmable limit‑switch polarity with dual optical/electrical safety logic.
- Automatic signal‑optimization calibration compensating scale mis‑alignment and light contamination.
- Three‑state differential alarm output for fault diagnostics.

Buying Guide and Applications
Selection Guide for Lab‑Scale Encoders
When choosing an encoder for laboratory micro‑detection, prioritize size, resolution, and configurability. The MicroE MII5730‑AB‑1000 offers an ultra‑compact form factor (under 10 mm height) that fits tight enclosures, while its programmable interpolation (X4‑X16384) lets you match the resolution of any precision controller. Evaluate the travel length you need – the metal strip version can be cut to a maximum of 30 m, ideal for long‑range linear stages, whereas the glass grating version provides sub‑micron accuracy for short‑range metrology. Verify that the encoder’s output bandwidth (up to 50 M counts/s) aligns with your controller’s maximum count rate to avoid missed pulses.
Installation & Alignment Tips
The MII5730‑AB‑1000’s ±0.15 mm gap tolerance and ±1°/±2° axis alignment simplify set‑up. Start by mounting the read head with the supplied brackets, ensuring the scale is parallel within the tolerance range. Use the built‑in auto‑calibration routine through SmartPrecision II; the system will compensate for minor mis‑alignments and surface contamination. The dual‑layer shielded cable tolerates tight bends (20 mm radius) without signal degradation, allowing clean routing in cramped lab cabinets.
Maintenance & Reliability
Because the encoder uses non‑contact optical measurement, there is no mechanical wear on the read head. Routine checks should focus on keeping the scale surface free of dust and oil; the large‑area photodiode and multi‑stage optical filter already provide strong immunity to light contamination. The device is CE‑EMC compliant and has been calibrated against NIST‑traceable laser interferometers, guaranteeing long‑term accuracy for at least five years under normal lab conditions.
Why Choose MicroE’s Mercury II Platform?
Mercury II encoders combine miniature packaging with full programmability, enabling customers to tailor interpolation, bandwidth, filter settings and limit‑switch logic without hardware changes. The integrated electronics reduce wiring complexity, and the dual‑mode limit switches add a safety layer for critical medical and semiconductor processes. Compared with legacy encoders, the MII5730‑AB‑1000 delivers up to 39 % less thickness while maintaining nanometer‑scale resolution and robust signal integrity over 10 m cable runs.
Buyer FAQ
What measurement ranges are available for the MII5730‑AB‑1000?
