Product Overview

S81-PL-5-Y03-NNV - 951551120 - S81 Laser Distance Sensors is a TOF laser distance sensor designed for distance measurement, pallet positioning, presence detection and level-related applications. The S81-PL-5-Y03-NNV configuration combines a specified measurement range with defined switching, analogue and/or serial interfaces, making the order code relevant to both mechanical and control-system integration.

Measurement and Interface

Important technical values include Optic function: Distance sensor, Output: NPN + analog 0…10 V, Connection: M12 connector, Light source: Red laser 665 nm, class 2, Measurement range: 300…4000 mm, Repeatability: ±4 mm, Response time: 5 ms, Switching frequency: 80 Hz. These are not interchangeable attributes: the maximum distance determines the usable measurement envelope, the analogue output provides the process value where specified, and the serial interface supports structured integration with the machine or controller.

Installation Considerations

Installation should account for the measurement path, target geometry, connector access and required communications wiring. For distance sensors, the mechanical placement is part of measurement performance because the target must remain within the specified range and the optical axis must be kept clear.

Selection for Automation Systems

This product is therefore suited to distance measurement, pallet positioning, presence detection and level-related applications, including machine-positioning and material-handling tasks where distance must be monitored rather than only detected as a simple on/off condition.

Typical Applications

S81-PL-5-Y03-NNV - 951551120 - S81 Laser Distance Sensors is suited to distance measurement, pallet positioning, presence detection and level-related applications. Match the measurement range and controller interface to the machine design.

Exact Configuration for Procurement

When ordering S81-PL-5-Y03-NNV - 951551120 - S81 Laser Distance Sensors, the complete model S81-PL-5-Y03-NNV and order code 951551120 should be retained as the purchasing reference. The principal configuration points for this item are Optic function: Distance sensor; Output: NPN + analog 0…10 V; Connection: M12 connector; Light source: Red laser 665 nm, class 2; Measurement range: 300…4000 mm; Repeatability: ±4 mm. These parameters should be checked against the existing machine drawing, controller wiring, mounting arrangement or bill of materials before substitution. This avoids treating a family-level part number as interchangeable with a different optical, electrical or mechanical variant.

Maintenance and Replacement Value

For maintenance use, S81-PL-5-Y03-NNV - 951551120 - S81 Laser Distance Sensors is most useful when the replacement part preserves the same functional role and interface. Keep the exact model identifier and order code with the equipment documentation so the next procurement cycle can reproduce the intended configuration without relying on a similar-looking family member. This is particularly relevant for S81-PL-5-Y03-NNV products, where changes in output type, optical configuration, connection or mounting format can change how the part integrates with the machine.
