Optical Positioning Sensor for Industrial Fish Filleting Machines

Product Specifications

Technical details and manufacturing context for Optical Positioning Sensor

Definition

In an Industrial Fish Filleting Machine, the Optical Positioning Sensor is a critical component used to accurately locate and track the position of fish carcasses or fillets as they move along the processing line. It enables precise cutting, portioning, and sorting by providing real-time positional data to the machine's control system. The sensor typically emits a beam of light (laser or LED) towards a target area. It detects the reflection or interruption of this beam by an object (e.g., a fish). By analyzing the received light signal (e.g., time-of-flight, triangulation, or image processing), it calculates the object's exact X, Y, and sometimes Z coordinates relative to the sensor's reference frame. This positional data is then used by the control system to adjust cutting blades, portioning mechanisms, or sorting gates in real time, ensuring consistent product quality and minimizing waste. The sensor is designed for harsh industrial environments, with a housing made of aluminum or stainless steel for corrosion resistance. It operates over a measurement range of 0–200 mm with a resolution of 0.01 mm, linearity of ±0.05% F.S., and repeatability of ±0.02 mm. The response time is 1–5 ms, and it operates on a 24 V DC supply (±10%) with a 4–20 mA analog output. It is rated for operating temperatures from -40 to 85 °C and offers ingress protection from IP54 to IP67 per IEC 60529. The weight varies from 0.5 to 2.0 kg depending on housing and cable length. These specifications are typical reference ranges; for the actual model, verify with the manufacturer. The sensor's working principle relies on optical reflection or interruption, making it suitable for non-contact measurement of moving objects. It is essential to select the appropriate sensor based on the specific application requirements, including measurement range, resolution, and environmental conditions. Regular maintenance includes cleaning the optical lens and checking for alignment. If the sensor fails to provide stable signals, it may indicate contamination, misalignment, or component degradation. Always consult the manufacturer's documentation for installation, calibration, and troubleshooting procedures.

Working Principle

The sensor emits a light beam (laser or LED) towards the target area. When an object, such as a fish, enters the beam, it reflects or interrupts the light. The sensor's photodetector (e.g., CMOS/CCD) captures the reflected or transmitted light. By analyzing the signal using methods like time-of-flight, triangulation, or image processing, the sensor calculates the object's position in X, Y, and sometimes Z coordinates relative to its reference frame. This data is output as a 4–20 mA analog signal to the machine control system, enabling precise positioning and tracking.
