Product Overview

EX-29A is an EX-20 series (Ver.2) amplifier built-in ultra-compact photoelectric sensor. It features a long sensing range, clear beam spot using red LED dot light source. Application includes detecting presence of chip components, checking protrusion of wafer, and sensing objects from an opening. The EX-20 series achieves reductions in power consumption of up to 65 %. These sensors contribute to environmental friendliness. The EX-20 series become significantly stronger against inverter light and other extraneous light. The beam-receiving photodiode and the A/D conversion circuit have been fabricated on a single chip optical IC (full custom). Hence, in spite of its miniature size, it has a performance and reliability which is equal to or better than the conventional product. The sensor incorporates a sensitivity adjuster in spite of its miniature size. It is convenient when you need fine adjustment.
  • Miniaturization by using single chip optical IC, waterproof IP67 (IEC)
  • Incorporates a sensitivity adjuster even in this size, identical size
  • NPN open-collector transistor output, light-ON output operation
  • Sensing range from 30 to 200mm, 0.5ms or less response time
  • Retroreflective type, side sensing
  • Bright 2-color indicator
  • 12 to 24VDC plus or minus 10% Ripple P-P 10% or less supply voltage range
  • 13mA or less current consumption, DC-12 or DC-13 output (utilization category)
  • Polyarylate enclosure, polyarylate lens
  • Ambient temperature range from -25 to +55°C, red LED (modulated) emitting element
