Omron D5C DATASHEET
Touch Switch
D5C
Unique 18 mm dia. Capacitive Touch Switch
with Choice of Three Actuators is Activated
with Only a Very Slight Physical Contact
• Lightweight objects, such as thin wire or foil can be accurately
detected.
• Solid-state switch activates the moment its actuator comes in
contact with the object.
• Amplifier, operation indicator, and sensitivity adjuster are builtin on all models.
• Conforms to IEC IP67 and NEMA Type 6, 6P.
• Actuators can be freely interchanged between switch units.
• A unique free-attachment version allows any kind of actuator
antenna to be attached.
