The Topcon LS-110D Digital Laser Receiver is a high-precision laser receiver designed to improve the speed and accuracy of elevation and vertical alignment work on construction, grading, earthwork, drainage, and site preparation projects. Featuring a digital readout that displays the exact distance from grade, the LS-110D gives operators more information than a conventional laser receiver with basic directional indicators.

The LS-110D features a large 90 mm (3.5 in.) vertical detection range, a 70 mm (2.7 in.) digital readout range, and five selectable on-grade resolutions ranging from a precise ±0.5 mm (±0.02 in.) to ±10 mm (±0.50 in.). This allows operators to adjust receiver sensitivity based on the precision requirements of the job.

Large front and rear LCD displays provide 9 channels of grade information, while orange, green, and red LED indicators provide additional visual guidance. The receiver also includes selectable buzzer levels, a Hold function, integrated bubble tube, strobe light suppression, and two built-in magnets for vertical applications.

Built for demanding jobsite conditions, the LS-110D carries an IP67 dust and water protection rating and operates from -20°C to 50°C. It is an ideal receiver for compatible Topcon rotating lasers, including the RL-SV2S, RL-H4C, and RL-200 Series.

Key Features

Digital Distance-to-Grade Readout

The LS-110D digitally displays the distance to on-grade, giving operators a precise measurement instead of relying solely on arrows or audible signals.

Units can be displayed in millimeters, centimeters, inches, or fractional inches, allowing operators to work in their preferred measurement format.

Five Selectable Accuracy Resolutions

The LS-110D provides five selectable on-grade resolutions:

• ±0.5 mm (±0.02 in.)
• ±1.0 mm (±0.05 in.)
• ±2.0 mm (±0.10 in.)
• ±5.0 mm (±0.20 in.)
• ±10.0 mm (±0.50 in.)

This flexibility allows the receiver to be configured for high-precision work or broader grade-checking applications.

90 mm Extra-Wide Beam Detection

A 90 mm (3.5 in.) vertical detection range provides a large target for quickly locating the rotating laser beam.

The vertical detection range extends from -30 mm to +60 mm (-1.1 in. to +2.3 in.).

70 mm Digital Readout Range

The digital LCD readout covers 70 mm (2.7 in.), ranging from -20 mm to +50 mm (-0.7 in. to +1.9 in.).

This provides operators with precise distance-to-grade information across a wide working area.

Front & Rear LCD Displays

Large LCD displays are positioned on both sides of the receiver, allowing grade information to be viewed from either direction.

The displays provide 9 channels of grade information for fast and intuitive elevation control.

Three-Color LED Grade Indicators

Orange, green, and red LED indicators provide additional visual grade information.

The LED indicators can be switched on or off depending on operator preference and working conditions.

Strobe Light Suppression

Built-in strobe light suppression helps prevent interference from jobsite strobe lights, improving receiver reliability in environments where flashing warning lights and construction equipment are present.

Horizontal & Vertical Operation

The LS-110D supports both horizontal and vertical applications. Its horizontal detecting range is ±45°, while two integrated magnets on the top of the receiver allow it to attach directly to suitable steel surfaces.

This makes the receiver useful for applications such as steel erection and vertical alignment in addition to standard elevation work.

Built-In Magnetic Mounting

Two round magnets are integrated into the top of the LS-110D, providing a convenient mounting option for compatible steel surfaces.

Hold Function

The Hold button locks the displayed measurement, allowing operators to remove or reposition the receiver and conveniently read the captured elevation result.

Selectable Audible Guidance

The built-in buzzer provides three selectable settings:

• Loud
• Low
• Off

Operators can select the setting that best matches jobsite conditions.

Built-In Bubble Tube

An integrated bubble tube helps operators maintain proper receiver alignment during measurement and grade-checking applications.

Up to 800 m Working Diameter

When used with specified compatible Topcon rotating lasers, the LS-110D supports a working diameter of up to 800 meters.

Up to 45 Hours of Battery Life

The receiver operates on a single AA/LR6 dry-cell battery and provides up to 45 hours of operation with an alkaline battery.

An LCD battery-level indicator helps operators monitor remaining battery capacity.

Automatic Shut-Off

The LS-110D automatically powers down after approximately 30 minutes of inactivity to help conserve battery life.

IP67 Environmental Protection

An IP67 rating provides protection against dust and water, helping the LS-110D withstand demanding outdoor construction environments.
