Optex FA CD33 Series Small Laser Displacement Sensors
Half-palm size. Ideal for built-in use with smaller machines.
- Specular reflection types have been added to the line up
- Control units for Mitsubishi Electric PLC are available
Specular reflection types
for measurements of specular and transparent objects.
Specular reflection types have been added to the line up to enable the measurement of transparent objects such as glass workpiece, as well as specular objects such as wafers, etc. This means that transparent and specular objects that were diffi cult to measure using diffuse-refl ective types can now be measured with stability.
Thickness measurements also possible
- When using a specular reflection type to measure transparent objects, not only surface displacement, but also thickness can be measured. As shown below, when the laser light is emitted at an angle, light reflected from both the front and rear surfaces of the glass are received by receiver element. Thickness measurements are possible by measuring between the peaks of these reflected light forms.

<Measurement conditions> The measurement conditions are as follows unless otherwise designated: Ambient temperature of +23℃ (normal temperature), Supply voltage 24 VDC, Response time: High-resolution, Center of measurement range, Measurement target: 50 ☓ 50 mm white ceramic.*1 Defined with center strength 1/e2 (13.5%) at the center of measurement range. There may be leak light other than the specified spot size. The sensor may be affected when there is a highly reflective object in the range of the light axis.*2 The response time is a time in which the sensitivity switching time has been added. The sensitivity switching time fluctuates within a max. range of 4 ms (6 ms for CD33-250N☐) depending on measurement conditions. Also, if the sampling period is long, the response time will also increase proportionately.Ex.: Sampling period 500 µs → 1000 µs: Response time 12.5 ms → Approx. 25 ms*3 If external teaching is selected, setting items can be changed as shown in the table below depending on the input time thereof.
