D4E-@N
Molded Terminal Models
Operation of Indicator-equipped Models
• The molded terminal model may be equipped with an operation indicator (neon lamp or LED) upon request to facilitate maintenance and
inspection.
• The operation indicator is designed to illuminate when the Switch is not operating. (Because of the molded terminal model, any change to the
Switch wiring cannot be made.)
AC Operation
• The operating voltage is 90 to 250 VAC.
• There is no difference in operating characteristics between D4E-
@N AC Models and corresponding D4E-@N Standard Models.
• There is no difference in dimensions between D4E-@N AC Models
and D4E-@N Standard Models.
Example:
Add “L” at the frond of “N”, which is suffix of a part number.
Basic type: D4E-1A23N
When placing your order for the molded terminal model with an neon
lamp operation indicator, specify the model number as D4E-1A23LN.
Internal Circuit
DC Operation
• LED indicator is provided.
• As a rectifier stack is incorporated, into the unit and no directionality
exists for connection of + and
− , this type can also be operated on AC.
• Voltage ratings of LED indicators are as shown in the table below.
Example:
Add “L2” at the frond of “N”, which is suffix of a part number.
Basic Model: The model number of the D4E-1A23N with a built-in
24-V LED indicator is D4E-1A23L2N.
Internal Circuit
The molded-terminal model is available with
right-hand and left-hand leads and is
recommended for use where the Switch is
exposed to dust, oil or moisture. It can be used
like a screw-terminal model (with a cable), and
the dimensions and operating characteristics
are the same as for standard models.
