Linear Encoders

Product catalog summary

Overview: The document provides technical specifications for the LE series incremental linear encoders, detailing their dimensions, features, and ordering information.

Specifications:

Overall Length (OL): Varies based on Measuring Length (ML) with specific formulas for different ML ranges.
Graduation and Resolution: 20 um graduated glass with resolutions down to 1 um.
Measuring Length: Available up to 1,100 mm.
Output Signal: TTL/RS422 with a maximum output frequency of ≥ 50 kHz for LE50 and ≥ 250 kHz for LE10.
Mechanical Speed: Maximum of 1 m/s.
Accuracy: 5 um/meter.
Reference Mark: Periodic or distance coded, with periodic marks at 40mm spacing.
Supply Voltage and Current: 5 V ± 5% and ≤ 80 mA without load.
Environmental Protection: IP53 standard, IP64 with optional air inlet.
Temperature Range: Operating from -0°C to +50°C, storage from -20°C to +70°C.
Humidity: Up to 98% non-condensing.
Vibration and Shock Resistance: Vibration ≤ 100 m/s², shock ≤ 300 m/s².
Weight: 0.4 kg plus 0.7 kg per meter of measuring length.
Required Moving Force: ≤ 4 N.

Recommendations: The encoders are recommended for small manually operated machines and feature end-point mounting.

Ordering Information: Example provided as LE50-750D, where the model (LE50 or LE10), measuring length, and reference mark type (P for periodic, D for distance coded) are specified.
