ROHM RPR-0730 — High-Speed VCSEL Proximity Sensor for Precise Industrial Detection

ROHM's RPR-0730: High-speed, high-precision VCSEL proximity sensor

The RPR-0730 from ROHM combines a VCSEL light source and an analog phototransistor to deliver industry-leading proximity sensing for label printers, conveyors, copiers, and industrial automation. Engineered for high-speed detection, this compact optical sensor excels at identifying micro targets down to 0.1 mm with a 10 µs response time.

Key features and SEO keywords

• VCSEL emitter for superior beam directivity and micro-target detection
• Analog phototransistor output for fast, reliable signal processing
• High-speed proximity sensor — 10 µs response time
• Small package: 2.0 × 1.0 × 0.55 mm; visible-light cutoff resin for ambient-light immunity
• Ideal for label printer, conveyor, motor/gear rotation detection and compact automation

These attributes make RPR-0730 a strong choice for applications that demand both precision and speed: optical sensor, proximity detection, VCSEL proximity sensor, RPR-0730.

Practical applications

Use cases include print detection in label printers and copiers, paper/jam sensing, object detection in conveyor systems, sample routing, and motor or gear rotation monitoring in robotics and industrial equipment. The sensor’s small form factor enables integration into tight spaces where LED-based sensors struggle.

Why choose RPR-0730? It reliably rejects ambient lighting, supports high-frequency motion, and detects extremely fine features — improving throughput and reducing false triggers in automated systems.

Availability & sample: Mass production began October 2025. Sample price: JPY 350 (excl. tax). Samples and commercial units are available through authorized distributors and e-commerce channels.
