• Excellent reliability
  High performance characterized by the smallest detectable hole diameter of 8 mm and margin in operation of over 30 times as much as operation level for transmitter and receiver circuits ensures detection even with minor soiling of lens.
• Easy optical axis alignment
  Transmitter and receiver are provided with devices exclusively for optical axis alignment and lamps are illuminated when the optical axis is aligned, facilitating accurate alignment.
• Superb vibration and waterproofing
  Case and structure time-tested in press safety sensors are employed for transmitter and receiver, withstanding adverse environment.
• Streamlined circuit design has further reduced power consumption.
  Unitization of transmitter and receiver has achieved about 50% reduction of size from the conventional model.
• Air purge hood or water cooling jacket can be attached as required.
