Limit Switchs

Features

-----------------------------------------------------------------------------------------------------

■

Double-circuit type of limit switch, is widely used

■

With strong aluminum cast outer shell

■

High mechanical strength

■

Water-proof, oil-proof construction

■

Structure preventing oil, water and pressure

■

Indicating plate with setting position is installed in it, so it is easy to

maintain

■

Various of actuators is taken convenience for using

■

Built-in contact stand has double-spring, so it has long mechanical life

NOTES:

■

Inductive load has a power factor of 0.4 min.(AC) and a time constant of 7

msec.max.(DC).

■

Lamp load has an inrush current of 10 times the steady-state current,while

motor load has an

■

inrush current of 6 times the steady-state current.
