High-precision Optical Switch
D5F
CSM_D5F_DS_E_2_2
Optical System Achieves 1-μm Operating Position
Repeatability in this 4-way Switch
• No-contact structure for high reliability.
• Ceramic materials in measuring part for superior resistance
to abrasion.
• Two different output types (PNP and NPN) available.
• Less abrasion and damage of mechanical contacts compared
to switches with contacts, reducing fluctuation in the output.
• More compact than previous OMRON models: 40% less mass,
15% lighter across the operating width.
Be sure to read Safety Precautions on page 4 and Safety Precautions for All
Limit Switches.

Safety Precautions
Refer to Safety Precautions for All Limit Switches.
Precautions for Safe Use
Do not impose any force exceeding 29.42 N max. on the cable,
otherwise the cable may break. Make sure that the bending radius of
the cable is at least R20 mm.
Precautions for Correct Use
Connections
• Take the residual voltage (2 V max.) into consideration when
connecting a load or power supply.
• When the internal circuit of the D5F is open, there will be a leakage
current of 0.15 mA maximum and a residual voltage on the load.
Check the release voltage of the load before use.
Handling
Do not drop or impose external force, such as shock, on the D5F.
Otherwise, the D5F may malfunction or lose its accuracy.
Noise
If the power supply line is affected by excessive noise, the D5F may
lose its accuracy.
Refer to the following and if the noise level is excessively high, take a
proper countermeasure, such as the use of a noise filter.
Level

1.5kV p-p
Influence on accuracy

Make sure that the ripple rate of the power supply is 10% maximum.
Operation
Do not press two or more plungers at the simultaneously, otherwise
the D5F may break.

Operation
Operating Environment
The operating environment has a significant effect on the D5F.
Consult your OMRON representative before using the D5F in
environments with different cutting oil, solvent, or gas.
Testing has been performed for the following 12 types of cutting oil.
Consult with your OMRON representative for application under other
conditions, such as other cutting oils, solvents, and gases.

Precautions
<Light Source Burnout>
The D5F does not use any contacts. Therefore no contact failures will
result. If the LED light source burns out due to noise or any other
cause, the following will result.
[email protected]: The output transistor is kept turned OFF.
[email protected]: The output transistor is kept turned ON.
Take the above into consideration and install a stopper mechanism so
that the machine will not be damaged or the Switch will not be pressed
excessively if the output transistor does not operate properly.
<Adhesive Agent>
The ceramic chips are glued with epoxy resin that may deteriorate
due to cutting oil or warm solvent. In the worst case, the chips may fall
off. The chips can withstand certain cutting oils or acetone. Check the
operating environment before using the D5F.
