D4F Small Safety Limit Switch

The volume is reduced to one quarter of the volume of our company's conventional types of
limit switches (30 (W) × 18 (L) × 60 mm (H)).
Optimal for the downsizing of machinery and equipment.

• The conventional types of limit switches with a direct opening mechanism required 18 degrees for a movement until operation because its direct opening point is long (Our company's conventional types of limit switches).
• The D4F requires 6 degrees to respond.
• On the table that allows machine tools etc. to move at an increasing speed, the moment the dog pushes the actuator, the D4F responds.
• With the development of smaller versions of machines, the D4F saves space and fits in a smaller space.

D4F models of two-contact construction (1NC/1NO and 2NC) and those of four-contact
construction (2NC/2NO and 4NC) are available.
The auxiliary contact can be used for monitoring input of control circuits and indicator lighting.

Positioning in Steps of 9 Degrees

For a roller lever type of switch, grooves are incised on the body and the cam of the actuator, to allow positioning in steps of 9 degrees.
