Reliable object detection in limited area
CE , Korean S Mark Approved
Korea’s S-mark certification : Excluding 5 m cable length type
Features
Stable convergent distance sensing
Due to convergent distance sensing, the color or material of the object has almost no effect. Further, the background also has very little effect, enabling stable sensing.
EX-43: Correlation between material and sensing range
Compact size (W10 x H29 x D18 mm W0.394 x H1.142 x D0.709 in)
It can be installed in a limited space.
Various applications
Diffused beam type
Even in a limited sensing area, the sensor is not affected by small perforations or unevenness. It is suitable for presence detection.
Spot-beam type
– Visible red spot beam allows easy targetting.
– It is suitable for positioning because of its 0.05 mm 0.002 in repeatability.

NOTE ： Mounting bracket is not supplied with the sensor. Please select from the range of optional sensor mounting brackets (two types).
Note 1 : The sensor does not detect even a specular background if it is separated by the distance specified below.
EX-42…150 mm 5.906 in or more, EX-44…300 mm 11.811 in or more, EX-43…100 mm 3.937 in or more
(These are typical values. However, the specular background should be a plane surface, directly facing the sensor. A spherical or curved background may be detected.)
5 m 16.404 ft cable length type
5 m 16.404 ft cable length type (standard: 2 m 6.562 ft) is also available.
When ordering this type, suffix “-C5” to the model No.
(e.g.) 5 m 16.404 ft cable length type of EX-42 is “EX-42-C5”.
