• Measurement Principle: HDDM™ optical time-of-flight for precise direct diffuse distance measurement.
• Measuring Range: 50 mm to 12,000 mm at 90% remission; 50 mm to 5,300 mm at 18%; 50 mm to 3,100 mm at 6%.
• Light Source: Infrared laser diode at 827 nm wavelength, Class 1 eye-safe per IEC 60825-1:2014.
• Response Time: Selectable from 2.5 ms (Super Fast) up to 96.5 ms (Super Slow) across five speed settings.
• Repeatability: ≥ 0.5 mm to 5 mm, depending on speed setting and target remission factor.
• Measurement Accuracy: Typical ± 10 mm for consistent distance readings.
• Supply Voltage: DC 12 V to 30 V with reverse-polarity protection; Vs > 18 V required when IO-Link is active.
• Power Consumption: ≤ 1.7 W at +20 °C without load in Slow speed setting.

Interface and Communication Features

• Output Q1: One push-pull digital output (PNP/NPN) with IO-Link V1.1 bidirectional communication.
• Output Q2: Shared configurable channel — selectable as analog current (4–20 mA, ≤ 450 Ω), analog voltage (0–10 V, ≥ 50 kΩ), or digital push-pull.
• Multifunctional Input: One MF input for flexible control and configuration tasks.
• Electrical Connection: M12 male connector, 5-pin, for secure industrial wiring.
• Integrated Aiming Aid: Optical LED alignment assist for quick and visible target acquisition.

Environmental and Mechanical Durability

• Operating Temperature: -30 °C to +55 °C (at Uv ≤ 24 V) for demanding industrial environments.
• Storage Temperature: -40 °C to +75 °C for safe off-duty handling.
• Enclosure Protection: IP65 rating per EN 60529, resistant to dust and water jets.
• Housing Material: Plastic (ABS/PC) body with acrylic glass (PMMA) optical window.
• Dimensions: 32 mm × 58.6 mm × 42.7 mm (W × H × D) for compact integration.
• Weight: Approximately 65 g — lightweight and easy to mount.

Installation Guide

• Mount the DT35-B15851 securely using the 32 mm × 58.6 mm body footprint and standard brackets.
• Align the sensor toward the target using the integrated optical aiming LED for fast setup.
• Connect the M12 5-pin male connector to a DC 12–30 V supply with correct polarity protection.
• Verify that Vs > 18 V when you activate IO-Link, and Vs > 13 V for analog voltage output.
• Select the response speed (2.5 ms to 96.5 ms) to balance reaction time against signal stability.
• Configure output Q2 as analog current, analog voltage, or digital push-pull per your control needs.
• Keep the PMMA optical window clean and free from dust or condensation for accurate readings.
