Omron, ZC-[]55 Series

• Small, High-precision Enclosed Switches with Built-in Basic Switches for High Repeatability and Durability of 10 Million Operations Minimum.

• Same mounting pitch as Z Basic Switch.

• Requires less operating force than conventional limit switches.

• Lineup includes modes with operation indicators for easy maintenance and inspection.

• Approved by EN, UL, CSA, and CCC (Chinese standard). (Ask your OMRON representative for Information on approved models.)

Inrush current	NC	30 A max.
Inrush current	NO	15 A max.

Note:The above figures are for steady-state currents.

Note:Inductive loads have a power factor of 0.4 min. (AC) and a time constant of 7 ms max. (DC).

Note:Lamp load has an inrush current of 10 times the steady-state current.

Note:Motor load has an inrush current of 6 times the steady-state current.

Note:The above ratings were tested under the following conditions according.
(1) Ambient temperature:+20±2°C
(2) Ambient humidity: 65±5%RH
(3) Operating frequency:20 operations/min.
