Optical Absolute Position Sensors

Optical absolute position sensors measure the stroke of a hydraulic cylinder. They measure the stroke with high accuracy of less than 0.1mm, are integrated and do not involve invasive mechanical work such as drilling into the piston rod. The main applications of these sensors are continuous measurement on steering cylinders, suspensions, and stabilisers.

Design and Specifications

Model	Type	Supply (V)	Load resistance (kΩ)	Output type
OIS22	Absolute optical position sensor	8V - 30V	20 - 100 kΩ	Analog 0,5 - 4,5 V
OIS22	Absolute optical position sensor	8V - 30V	20 - 100 kΩ	Analog 4 - 20 mA

Operation and Applications

Optical absolute position sensors are designed for the mobility sector and specifically for agricultural and earthmoving machinery working in harsh environments.
Unlike single position sensors, absolute position sensors measure the stroke of a hydraulic cylinder, making it possible to continuously monitor the exact position of the piston rod within the cylinder.

Optical single position sensors

Optical single position sensors measure a single point on the stroke of a hydraulic cylinder. They are integrated, tamper-proof, and insensitive to electromagnetic fields. We have designed the optical position sensors specifically for agricultural and earth-moving machinery; the robust design of the sensors guarantees optimal operation even when the machines on which they are applied operate in harsh environments.Features High input voltage range High temperature range High current output Meets ISO 7637 normative, including pulse 5 “load dump“ MTTF 120 years Inversion of polarity protection Overload protection Smart interface and smart algorithm Compliant to RoHS European Directive Designed for earth moving environment Customizable on different parameters

Level Sensors

Level sensors are optoelectronic devices based on emitters and receivers that work on the principle of reflection and refraction.The Optoi level sensor is based on optical prism technology which allows the light emitted by a LED to be captured by the receiver in the absence of liquid. On the other hand, in the presence of liquid, the optical channel is perturbed, thereby causing the absence of a signal on the receiver.Features Small size Simply installation Modular level sensing Robust optical technology High media compatibility
