Description
Product Characteristics
The ELRF-E16 laser rangefinder module is a laser ranging module developed based on our company’s independently researched and developed 1535nm erbium laser.It adopts a single-pulse Time-of-Flight (TOF) ranging method with a maximum ranging distance of ≥5km.Composed of a laser,transmitting optical system,receiving optical system,and control circuit board,it communicates with the host computer through a TTL serial port.It provides host computer test software and communication protocols, facilitating user secondary development.It boasts features such as small size,light weight,stable performance,high shock resistance,and Class 1 eye safety.
Product Function
The ELRF-E16 laser rangefinder consists of a laser,a transmitting optical system,a receiving optical system and a control circuit.
Visibility under the conditions of visibility is not less than 20km,humidity ≤ 80%,for large targets(buildings)ranging distance ≥ 6km;For vehicles(2.3m×2.3m target,diffuse reflectance ≥ 0.3)ranging distance ≥ 5km;For personnel (1.75m× 0.5m target plate target,diffuse reflectance ≥ 0.3)ranging distance ≥ 3km.
The ELRF-E16 Main functions:
a)single ranging and continuous ranging;
b)Range strobe,front and rear target indication;
c)Self-test function.

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.
