Laser type photo sensor

LDA	Digital laser sensor with separate amplifier
	High performance with easy handling!

Feature

Visible laser ray
High-speed response time, 60µsec(when fast mode)
3 kinds of beam can be chosen(Spot, area, line)
IP67 for sensor head
Sensitivity correcting function is provided
Coaxial-reflection type is also lined-up

Applications

Warp detection(Through-beam type)	Transparent detection(Coaxial retro-reflection type)


Height/width detection(Through-beam, length measurement type)	Uneven goods detection(Coaxial retro-reflection type, long distance)


Tip work detection(Coaxial reflection type)

Mode

Teaching mode

One-point teaching It can set not to detect back-ground by teaching under no object.

Two-point teaching It sets the threshold at the center between 2 points teaching(object and no object).

Auto teaching It can set the sensitivity automatically.(it can be set even if the object is moving)

Teaching length measurement It can distinguish the width(length) of object in the specific area. If it would be over +10%, output 1 is executed and if over -10%, output 2 is executed.


Teaching transparent object This mode is to detect the transparent object with retro-reflection type head.(Glass or plastic film etc.) It can detect the object with a little variation of light-receiving amount such as transparent objects by making a one- point teaching under no objects.

Zone teaching It can detect within the area between upper and lower limit. It can set during ±10% of light-receiving amount. It can set without influence of background.

Caution

This product is emitting visible laser beam and is classified as Class 2 by JIS C6802/IEC Laser Safety standard. When exporting to USA, US laser control, FDA(Food and Drug Administration) is applied. Please ask us in details.
