R4N

miniature industrial relays

Design

Improvement of the functionality of the mechanical

indicator (W): it is mounted on an insulation base of

the unit of the movable contacts; the changes provide

the appropriate position in the window in the upper side

of the housing irrespectively of the number of operations

performed by the relay.

Improvement of the efficiency of the electromagnet:

an innovational technology of connecting elements has

been introduced, which guarantees more reliable opera-

tion of the relay.

Strengthening of the insulation in the area of the

contact plate: polyamide PA66 has been applied; it has

very good mechanical and electrical parameters and best

thermal properties.

Application of electronics made in the SMD techno-

logy: additional features L (LED diode) and D (diode)

are located on the printed circuit board; the change

of the position of the LED diode and optimization

of the quality and intensity of its light provide certainty

that the relay is in operation status when the LED is on.

Test buttons R4P-0001 and plugs R4W-0003 need

to ordered saparately. They substitute buttons type T.

To exchange by Customer themselves. Information

on test buttons (no latching) and plugs - page 12.

Dimensions - plug-in version (WT),

with lockable front test button type T

Dimensions - plug-in version, with test button

(no latching) or with plug (no manual operation)
