Photoelectric Distance measurement sensors S85 Series

Datasensing S85 Series

The S85 Series delivers precision distance measurement in a compact but robust industrial housing, using direct Time-of-Flight (ToF) laser technology. With measuring ranges up to 20 m, a visible red Class 2 laser for alignment, analog and digital outputs, and advanced connectivity, the series provides high-accuracy measurement, versatile integration, and industrial durability for demanding automation environments.

Design & Functionality

• The S85 uses a visible red Class 2 laser emission (≈ 658 nm) combined with ToF measurement, yielding 1 mm resolution, repeatability down to ~1 mm, and accuracy typically ~7-10 mm.
• Measuring ranges include ~0.2 … 10 m for standard versions (S85-…-Y03) and ~0.2 … 20 m for advanced versions (S85-…-Y13). 
• Outputs: Analog (selectable 0-10 V or 4-20 mA) plus two digital outputs; advanced models also support RS-485 serial interface. 
• Housing is industrial metal (zinc alloy / zamak), with standard M12 connector (5-pin or 8-pin depending on version) and protection rating IP67, designed for warehousing, intralogistics and manufacturing environments. 
• Configuration: Basic versions employ push-buttons, advanced versions include display for configuration and reading distance values. Response times vary by speed mode (Fast ~15 ms, Medium ~30 ms, Slow ~45 ms). 

Total Crossed Beams

(Here this term implies the sensor’s full measurement path reliability rather than literal crossed optical beams.)

• The S85 Series ensures a consistent measurement path even across long spans and varying target surfaces, enabling reliable distance detection up to 20 m with millimetric resolution.
• The combination of laser emission and ToF technology enables strong immunity to ambient light, background variations, and target reflectivity changes, resulting in stable performance in dynamic automation systems.

Beam Pitch Options

(Interpreted here as selectable measurement spans or model variants rather than literal beam spacing.)

• Standard variant: measuring range ~0.2 … 10 m (for white target) in Y03 versions.
• Advanced variant: measuring range ~0.2 … 20 m (for white target) in Y13 versions, with higher connectivity and display. 
• These options allow selection of the sensor best suited for your target distance, target contrast, environmental conditions, and measurement accuracy requirements — offering flexibility in system design.

Intrinsic Synchronism

• The electronics are fully integrated: the ToF measurement system, laser emitter, signal processing, analog/digital outputs and optional RS-485 interface are self-contained — no external sync wiring required.
• The sensor’s configuration, measurement and output logic are built-in, enabling quick installation and live measurement capability within a minimal warm-up time.

Operational Advantages

• High-accuracy long-range measurement: With measurement spans up to 20 m, 1 mm resolution, and repeatability ~1-2 mm, the S85 Series is ideal for positioning, distance measurement, level detection and object presence in large installations.
• Versatile outputs and connectivity: With analog outputs, digital outputs and RS-485 interface (in advanced models), the sensor integrates easily with PLCs, field buses and automation networks.
• Rugged industrial housing: Metal construction, IP67 protection, laser alignment aid and industrial connectors ensure reliable performance in logistical hubs, automation cells, outdoor installations or harsh factory conditions.
• Applications: Suitable for warehousing systems (automated stackers, guided vehicles), packaging machines, industrial vehicles, automotive manufacturing lines, conveyor span detection and any scenario where precise distance measurement, long range, industrial durability and flexible outputs/connectivity are required.
