Founded in 1979, Optex Co., Ltd. is one of the most technologically advanced manufacturer of Infra-Red sensing devices. Through itís intensive research and development, Optex is striving to be the market leader in Photoelectric Sensors and Non-contact Thermometers. Sensors are essential industrial requirements.
The "Photoelectric Sensor" plays an active role in automatic manufacturing processes. The "Displacement Sensor" measure the dimension of objects on the production line. The "Non-contact Thermometer" can measure surface temperature without making contact. Factory automation sensors contribute towards cost-effective as intelligent "eyes" to improve systems such like the analysis of process information and control of manufacturing lines.

Portable type non-contact thermometer (Thermo-hunters):
Portable non-contact thermometer enables temperature measurement without touching objects. It is desirable for food's temperature control where hygiene is required. It also brings a good solution for checking temperature safely at a distance from the dangerous atmospheres of which temperature and voltage are extremely high. The performance of OPTEX thermometer is well received in the field of measuring instrument all over the world.

Two main types of Optex Thermo-hunters are readily available:

  1. The standard PT-2LD which has a range of -40 to 510C and a response time of less than 800ms
  2. The PT-7LD with a measuring range of -20 to 200C and a response time of 700ms.

Other than these, the Optex BUILT-IN2 fixed mounting unit is also available. The model includes a built-in digital display and has a measuring range of 0 to 500C.
