Bosch LR 45 Professional Laser Receiver

Bosch LR 45 Professional Laser Receiver

The Bosch LR 45 Professional Laser Receiver is a precision instrument engineered for use with Bosch rotary laser levels such as the GRL 300 HV, GRL 300 HVG, and GRL 400 H. Designed to capture both red and green laser beams, it delivers reliable performance in demanding construction and surveying environments.

Key Features

• Dual‑Colour Detection: Capable of receiving red (650 nm) and green (520 nm) laser beams, ensuring compatibility with a wide range of Bosch rotary laser systems.
• Wide Reception Angle: The receiver’s optical design allows it to capture laser signals from a 360° field, making alignment straightforward regardless of the device’s orientation.
• Maximum Range: Effective detection up to 300 meters in clear conditions, providing ample coverage for large-scale projects.
• Robust Construction: Encased in an IP66‑rated housing that resists dust and water ingress, the receiver is suitable for outdoor use and harsh job sites.
• Integrated Mounting Bracket (RB 45): The included RB 45 mounting bracket offers secure attachment to standard tripod heads or other mounting systems, facilitating quick setup and repositioning.
• Power Supply: Operated by two standard AA batteries, the receiver delivers long battery life while remaining lightweight and portable.
• Compact Size: The small footprint allows it to be carried easily in a toolbox or mounted on a workbench without obstructing other equipment.

Technical Specifications

Applications and Use Cases

The LR 45 Professional Laser Receiver is indispensable in a variety of construction, civil engineering, and architectural tasks:

• Leveling and Alignment: Used to establish horizontal or vertical reference planes when installing foundations, slabs, or structural elements.
• Flooring Installation: Provides accurate guidance for laying tiles, hardwood, or engineered flooring across large areas.
• Wall Framing and Drywall: Assists in maintaining straight lines and level surfaces during framing, sheathing, and drywall hanging.
• Electrical and Plumbing Rough‑In: Enables precise placement of conduits, pipes, and cable trays by referencing laser guides.
• Surveying and Mapping: Supports rapid data collection for site surveys, boundary delineation, and topographic mapping when paired with compatible laser levels.

Installation and Setup

1. Mount the Receiver: Attach the RB 45 bracket to a tripod or other stable surface. Secure the receiver onto the bracket, ensuring it is level and centered.
2. Power On: Insert two fresh AA batteries into the designated compartment. The receiver will automatically detect the laser beam once the source is activated.
3. Align with Laser Source: Point the receiver toward the laser emitter. Adjust the angle until the sensor detects both red and green beams simultaneously, confirming proper alignment.
4. Verify Range: Move the receiver to various distances up to 300 m while maintaining line of sight. The device should consistently capture the beam without loss of signal.

Maintenance Tips

• Clean the Sensor Lens: Use a soft, lint‑free cloth to wipe the optical surface periodically, preventing dust accumulation that could degrade performance.
• Check Battery Life: Replace AA batteries when the receiver’s indicator shows low power or when accuracy diminishes.
• Inspect Mounting Hardware: Ensure screws and brackets remain tight; vibration on job sites can loosen connections over time.
• Store Properly: When not in use, keep the receiver in a dry environment to avoid moisture ingress, even though it is IP66 rated.

Compatibility Summary

The LR 45 Professional Laser Receiver is specifically engineered for Bosch rotary laser levels:

• GRL 300 HV (Red)
• GRL 300 HVG (Green)
• GRL 400 H (Dual‑Colour)

Its dual‑colour detection and wide reception angle make it a versatile companion for any project requiring precise laser guidance.
