Technical Datasheet: SICK DME4000-111

Product Type: Long Range Laser Distance Sensor (Time-of-Flight)

Part Number / Model: DME4000-111 (1029789)

Data Interface: SSI (Synchronous Serial Interface)

1. Product Characteristics & Application

• Sensing Principle: High-precision Time-of-Flight (ToF) laser measurement.

• Measuring Range: 0.15 m to 50 m when tracking target on standard “Diamond Grade” reflective tape.

• Light Source: Visible red laser beam (Class 2 laser product, complies with 21 CFR 1040.10 and 1040.11).

• Typical Light Spot Size: 130 mm diameter at a distance of 70 meters.

• Special Features: Built for high-speed industrial position tracking and measurement loops. Features an integrated diagnostic liquid crystal display (LCD) on top and mechanical alignment status indicators. Highly utilized for precise positioning of crane systems, automated storage and retrieval systems (ASRS), transfer cars, and large-scale robotic tracking grids.

2. Electrical Data & Interface
