E4PA-N
Ultrasonic Displacement Sensor
Nomenclature
Setting Plug
The E4PA-N is set up by aligning the notch on the Sensor with one
of the triangular marks on the Setting Plug and inserting the Setting
Plug into the Sensor.
Note: 1. Analog Output Characteristics when Setting Plug is inserted at E2/
E3 Position:
The analog output characteristics will change from (1) to (2) to (3),
in that order, each time the Setting Plug is inserted with the E2/E3
position aligned with the notch on the Sensor.
2. The analog output value can be compensated so that the sensing
surface (0 mm) of the Sensor is 4 mA/0 V regardless of the nearest
sensing point setting.
This function is useful when using Controllers without a scaling
function. Sensing is not possible, however, for characteristics
within the dead band distance and current/voltage output values
may not be stable.
Indicator Display and Analog Output Characteristics
Note: 1. Lit: The sensing object is within the sensing range.
Not lit: The sensing object is not within the sensing range.
2. Output indicator just prior to occurrence of malfunction.
Mutual Interference Prevention
The E4PA-N provides a sync input to prevent mutual interference.
When the fifth pin of the Sensor I/O Connector’s M12 Connector is interconnected, mutual interference can be prevented for up to five Units. The
Sensors will mutually oscillate, however, causing a delay in measurement time by the mutual interference cycle time per Sensor
×
number of Units
+ response time. When the sync inputs are not connected, the mutual interference prevention function is disabled.
(For example, if three E4PA-LS200-M1-N are connected, the response time for one Sensor is 34 ms
×
3 S 195 ms = 297 ms.

1. Increase: As the distance increases, the output in-
creases. (LED A2 flash.)
2. Output from 0 mm: Increases from the sensing surface
to point A2. (LED A1 and A2 flash.) (See note 2.)
3. Decrease: As the distance increases, the output de-
creases. (LED A1 flash.)
