Ultra-compact Photoelectric Sensor EX-20 Ver.2
Panasonic — EX-20 Series
The receiving photodiode and the A/D conversion circuit are combined on a single full-custom optical IC, so despite its miniature size it matches or exceeds the performance and reliability of previous models. Thru-beam, retroreflective and diffuse reflective types are available.
Key Features
- Miniaturisation with a single-chip optical IC
- Sensitivity adjuster even in this size
- Long sensing range
- Clear beam spot from a red LED dot light source
- Low power consumption
- IP67 (IEC) waterproof
