3km LRF Module for Laser Distance Measurement

The Lumispot Tech ELRF-C16 is a compact and lightweight laser rangefinder module(distance measurement sensor), notable for being the smallest of its kind, weighing only 33g. It is a highly precise tool for measuring distances up to 3km, tailored for photoelectric systems where accuracy and reliability are paramount. This laser measurement sensor is eye safety-certified and offers a wide range of technical features.

Technical Features of The Laser Measurement Sensor:

The LRF module integrates an advanced laser, high-end transmitting and receiving optics, and a sophisticated control circuit. These components work together to provide a visible range of up to 6km and a vehicle ranging capability of at least 3km under ideal conditions.
It supports both single and continuous ranging, features range strobe and target indicators, and includes a self-inspection function for consistent performance.

Key Performance Attributes:

It operates at a precise wavelength of 1535nm±5nm and has a minimal laser divergence of ≤0.5mrad.
The ranging frequency is adjustable between 1~10Hz, and the module achieves a ranging accuracy of ≤±1m (RMS) with a ≥98% success rate.
It boasts a high-ranging resolution of ≤30m in multi-target scenarios.

Efficiency and Adaptability:

Despite its powerful performance, it is energy-efficient with an average power consumption of <1.0W at 1Hz and a peak of 5.0W.
Its small size (≤48mm×21mm×31mm) and light weight make it easy to integrate into various systems.

Durability:

It operates in extreme temperatures (-40℃ to +65℃) and has a wide voltage range compatibility (DC6V to 36V).

Integration:

The module includes a TTL serial port for communication and a specialized electrical interface for easy integration.
The ELRF-C16 is ideal for professionals needing a reliable, high-performance laser rangefinder, combining advanced features with exceptional performance. Contact Lumispot Tech for more information on our Laser Ranging Sensor for distance measurement solution.

Specifications

Interface Description

• Communication interface: RS422, baud rate 115 200 bps (default)
• Electrical interface: connector A1002WR-S-10P

Operating Precautions

• The module emits 1535 nm laser radiation that is Class-1 eye-safe. Nevertheless, deliberate direct eye exposure should be avoided.
• Always cover the receive lens while aligning the three optical axes; excessive return energy can permanently destroy the detector.
• The module is NOT hermetically sealed. Operate only in clean environments with relative humidity < 80 % to prevent laser damage.
• Maximum range depends on atmospheric visibility and target reflectivity. Fog, rain, dust or sand reduce range. Highly reflective objects (green foliage, white walls, exposed limestone) increase range; large beam-to-target angles decrease it.
• NEVER fire the laser at highly reflective targets such as glass or white walls within 15 m; the intense return pulse can destroy the APD.
• NEVER connect or disconnect cables while the unit is powered.
• Observe correct power-supply polarity; reversal will cause permanent damage.
