Barcode Reader for Sample Handling Systems

Product Specifications

Technical details and manufacturing context for Barcode Reader

Definition

The barcode reader is a component used in machinery and equipment manufacturing, specifically within sample handling systems. It automatically identifies and tracks sample containers by scanning their barcodes, ensuring accurate sample routing, preventing misidentification, and maintaining traceability throughout the handling process. The device decodes barcode symbologies and transmits data to the system's control unit.

Operating on the principle of optical scanning, the reader uses a light source (typically laser or LED) to illuminate the barcode pattern. A photosensitive sensor detects reflected light intensity variations representing black bars and white spaces. The analog signal is converted to digital data, decoded according to the barcode symbology (e.g., Code 128, QR Code), and transmitted via an interface (e.g., USB, RS-232) to the system controller for processing.

Key parameters include a scanning distance of 0–300 mm for typical 1D barcodes, a scan rate of 100–500 scans/s (higher for moving conveyor applications), and a resolution of 0.1–0.3 mm (minimum barcode element width readable). The reading angle tolerance is ±60° for pitch and skew. Operating temperature ranges from -20 to 50 °C, storage temperature from -40 to 70 °C, and humidity from 5 to 95% RH (non-condensing). Ingress protection is IP54–IP65 per IEC 60529, suitable for dusty or wet environments. Supply voltage is 5–24 V DC, with power consumption of 1.5–3.5 W depending on illumination and processor. Interfaces include USB, RS232, and TTL. Weight ranges from 100–300 g, and housing materials are ABS or PC (polycarbonate for higher impact resistance).

Materials on file include an optical lens (glass), CMOS/CCD image sensor, LED/Laser diode, plastic housing, and PCB with microcontroller. These specifications are reference ranges; verify model-specific values and standards with the legal manufacturer or supplier before procurement or integration.

Working Principle

The barcode reader uses a light source (laser or LED) to illuminate the barcode. A photosensitive sensor detects reflected light intensity variations corresponding to black bars and white spaces. The analog signal is converted to digital data, decoded according to the barcode symbology (e.g., Code 128, QR Code), and transmitted via interface (e.g., USB, RS-232) to the system controller for processing. The device must be positioned within the specified scanning distance and angle to ensure reliable reads.
