KEYENCE SR-2000 is an autofocus 1D/2D code reader designed for high‑speed, long‑range reading in industrial automation, logistics, and manufacturing applications. Autofocus automatically adjusts focus position during installation and tuning without manual intervention. High‑sensitivity 3.1‑megapixel CMOS image sensor (2048 × 1536 pixels) captures clear images even with dark, low‑contrast codes. Built‑in high‑intensity red LED illumination and green LED pointer. 3‑output photo MOS relay outputs. EtherNet/IP™ and PROFINET industrial Ethernet protocols supported. IP65 enclosure, 24 V DC, 0 … +45 °C operating temperature. Designed for trouble‑free, “install‑and‑go” performance in applications ranging from automotive part traceability to semiconductor FOUP ID reading and high‑speed conveyor scanning.
Applications:
-
Logistics and material handling conveyor code reading
-
Automotive part traceability and assembly verification
-
Semiconductor FOUP ID reading and yield tracking
-
Pharmaceutical and food packaging code inspection
-
Electronic PCB identification and quality control
-
High‑speed production lines requiring moving object code reading
