Miniature Limit Switch D4CC

• New center roller lever models that enable ganged mounting of up to 6 Switches.

• Cable connectors for easy Switch replacement.

• Triple-seal construction to provide IEC IP67 degree of protection.

• Operation indicators available for easy monitoring (standard indicator is lit when Switch is not operating).

• Approved by UL and CSA. (Ask your OMRON representative for Information on approved models.)



Rated voltage Non-inductive load (A) Inductive load (A)
Resistive load Lamp load Inductive load Motor load
125 VAC 1 1 1 0.7 1 1 1 1
30 VDC 1 1 1 1 1 1 1 1



Note: 1. The above current ratings are for steady-state current.
2. Inductive loads have a power factor of 0.4 min. (AC) and a time constant of 7 ms max. (DC).
3. Lamp loads have an inrush current of 10 times the steady-state current.
4. Motor loads have an inrush current of 6 times the steady-state current.
