Omron D4F Datasheet

Small Safety Limit Switch
D4F
A Smaller Limit Switch than
Ever Previously Produced.
Ideal for Applications to
Small-scale Machinery and
Equipment
• A noticeable reduction to 1/4 the size of OMRON's
conventional model.
• High-sensitivity safety limit switch.
• Built-in switches with two- or four-contact construction
are available.
• Degree of protection: IP67 (EN60947-5-1)
• Patent and design pending.
Features
A Dramatic Reduction in Size
The volume is reduced to one quar-
ter of the volume of our company's
conventional types of limit switches
(30 (W) × 18 (L) × 60 mm (H)).
Optimal for the downsizing of ma-
chinery and equipment.
High-sensitivity and Space-
saving
The conventional types of limit
switches with a direct opening
mechanism required 18 degrees for
a movement until operation be-
cause its direct opening point is long
(Our company's conventional types
of limit switches).
The D4F requires 6 degrees to re-
spond.
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.

Four-contact Construction is Available
D4F models of two-contact con-
struction (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 cir-
cuits 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 po-
sitioning in steps of 9 degrees.
