Key Performance Highlights

• The DT500-A311 keeps 1 mm repeatability across the full measuring range.
• Accuracy stays within ± 3 mm for stable distance feedback in control loops.
• A 12-bit resolution gives fine steps for precise position tracking.
• The 150 ms response time suits moderate-speed automation and monitoring tasks.
• Visible red laser class 2 simplifies alignment during commissioning.
• Temperature drift of 0.05 mm/K supports consistent readings in changing conditions.
• Ambient light immunity to 3,000 lx limits interference from factory lighting.
• EMC compliance to EN 61000-6-2 and EN 55011 improves抗干扰能力 in industrial settings.

Installation Guide

• Mount the sensor on a rigid bracket using the 69 mm x 50 mm x 153 mm housing footprint.
• Keep the glass window clean and aim the laser spot squarely at the target surface.
• Connect the 5-pin M12 connector and confirm the 10 V to 30 V DC supply polarity.
• Set the analog output to 0 mA to 20 mA or 4 mA to 20 mA before startup.
• Use the multifunctional input above 12 V to switch the laser off when needed.
• Respect the –10 °C to +45 °C operating range, or add a cooling case for higher heat.
• Verify IP65 sealing by tightening the connector and checking the window seal.
• Test repeatability and accuracy against a known reference after mounting.
