The KEYENCE SR-750 is an Ethernet-compatible 2D code reader engineered for short-range applications where reliable decoding and fast cycle times are critical. Designed for factory automation, it reads a wide range of symbols including QR, MicroQR, DataMatrix (ECC200/GS1), PDF417/MicroPDF, and major 1D barcodes such as CODE39, CODE128/GS1-128, ITF, and EAN/UPC, making it a versatile solution for traceability and quality control.

A high-sensitivity CMOS imager (752 × 480) with integrated red LED illumination and a visible Class 1 laser pointer (660 nm) ensures precise aiming and stable reads at close distance. The SR-750 delivers dependable performance within a 30–100 mm window for 1D codes (narrow bar 0.33 mm) and 40–80 mm for 2D codes (cell 0.25 mm), with a 60 mm focal distance. For integration, it offers Ethernet 10BASE-T/100BASE-TX and RS-232C connectivity with industrial protocols including TCP/IP, EtherNet/IP, PROFINET, FTP, SNTP, BOOTP, and MC protocol. Power options include 24 VDC ±10% or PoE Type A/B (36–57 V). Built for the shop floor, the unit is IP65-rated and resists high ambient light, ensuring consistent performance from commissioning to continuous operation.

Ideal for line-side workstations, robotic cells, and compact fixtures, the SR-750 helps machine builders and integrators shorten setup time while maintaining robust read rates across challenging materials and lighting. Its combination of PoE capability, rich protocol support, and rugged design reduces integration risk and total cost of ownership, and it provides additional peace of mind for maintenance teams as it is supplied with a 1-year warranty.
