D5F-3C@0
Replace @in the model number with the code for the Switch you require (i.e. 1
for Switches with a 1,000-mm cable and 3 for Switches with a 3,000-mm
cable).
Note: The degree of parallelism and squareness of the ceramic chip are
±5 µm/5 mm against the reference plane.

Precautions
■Correct Use
Do not impose any force exceeding 29.42 N on the cord, other-
wise the cord may break. Make sure that the bending radius of
the cord is at least 20 mm.
Connections
Take the residual voltage (2 V max.) into consideration when con-
necting a load or power supply.
When the internal circuit of the D5F is open, there will be a leak-
age 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.
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.
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.
Make sure that the ripple rate of the power supply is 10% maxi-
mum.
Operation
Do not press two or more plungers at the simultaneously, other-
wise the D5F may break.
Example: Two-directional Operation
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.
D5F-2B
# 0: The output transistor is kept turned OFF.
D5F-3C
# 0: The output transistor is kept turned ON.
Take the above into consideration and install a stopper mecha-
nism so that the machine will not be damaged or the Switch will
not be pressed excessively if the output transistor does not oper-
ate 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 ace-
tone. Check the operating environment before using the D5F.
