Classification Function
Linear output An analog 4 to 20 mA output signal proportional to the distance from the target to the face of the sensor
within the range of the 4 mA linear setpoint to the 20 mA setpoint.
Switching output A 100 mA, 40 VDC rated transistor output (separate power source required) adjustable within the range of the
4 mA linear setpoint and 20 mA linear setpoint.
Power ON Red LED illuminated when amplifier is connected to power source and energized.
Operation Red LED illuminated when the target is present within the range from the minimum sensing distance to the
target setpoint distance.
Span Green LED illuminated when the target is present within the range of the 4 mA linear setpoint and the 20 mA
linear setpoint.
Cable length selector Set to the length of cable (3 or 5 meters) supplied on the sensor head.
switch
4 mA linear adjustment Used to set the analog output at 4 mA when the target is at 20% of the rated sensing distance.
Adjustment method 1.
20 mA linear adjustment Used to set the analog output at 20 mA when the target is at 100% of the rated sensing distance.
Adjustment method 1.
Sensitivity Used to set the target distance that turns on the switching output.
Mode selector switch Determines the logic of the switching output circuit. In the NO position, the target turns on when the target is
present between the minimum sensing distance and the target setpoint distance. In the NC position, the
switching output turns on when the target is beyond the target setpoint distance.

LINEAR OUTPUT ADJUSTMENTS
Choose one of the two adjustment methods for setting the
LINEARITY adjuster. Adjustment of the 4 mA and
20 mA LINEARITY adjusters must be performed with the
standard target at positions of 20% and 100% of the rated
detecting distance away from the sensor.
Linearity Adjustment Method 1
1. Connect an ammeter across terminals 1 and 2. The
illustration shows the sensor connected to an amplifier
through socket P2CF-11.
2. Place the standard target at 20% of the rated detecting
distance away from the sensor unit.
3. Turn the 4 mA LINEARITY adjuster slowly clockwise (to
increase the output current) or counterclockwise (to
decrease the output current). Set the adjuster to a position
that reads 4 mA output on the ammeter.
4. Place the standard target at the rated detecting distance.
5. Turn the 20 mA LINEARITY adjuster slowly clockwise (to
increase the output current) or counterclockwise (to
decrease the output current). Set the adjuster to a position
that reads 20 mA output on the ammeter.
6. To fine tune the adjustment accuracy of the output current,
repeat the adjustment steps for 4 mA and 20 mA
LINEARITY adjusters.
Linearity Adjustment Method 2
1. Set the standard target at 20% of the rated detecting
distance away from the sensor.
2. Turn the 4 mA LINEARITY adjuster counterclockwise so that
the SPAN indicator remains OFF. Then slowly turn the
adjuster clockwise until the indicator illuminates. Stop
turning the adjuster at the position where the SPAN
indicator illuminates.
3. Set the standard target at the rated detecting distance away
from the sensor.
4. Slowly turn the 20 mA LINEARITY adjuster clockwise until
the SPAN indicator goes OFF. Then tur n the adjuster
counterclockwise until the indicator illuminates. Stop turning
the adjuster when the SPAN indicator illuminates.
SENSITIVITY ADJUSTMENTS
S
0.8
Place the standard target at the specified position. If the target
moves in parallel with the surface of the sensor unit, make the
adjustment after determining the position using the following
procedure.
1. Adjust the linear output according to Adjustment Method 1
or 2.
2. Calculate detecting distance X using the following formula:
X = S = setting distance
3. Adjust the distance between the sensor and the object to
be detected to distance X.
Slowly turn the SENSITIVITY adjuster clockwise (toward HIGH)
and stop turning when the OPER. indicator illuminates. Move
the target to confirm that the OPER. indicator illuminates when
the object to be detected is at the specified position and that
the indicator goes OFF when the target is moved away from
that position.
If the target moves in parallel with the surface of the sensor
unit, place the sensor at distance S.

The P2CF-11 socket has two hooks that secure the E2CA
amplifier to the socket. Be sure to allow at least 20 mm (0.79
in) clearance above and below the socket to gain access and
to release the hooks for servicing and maintenance. The
P2CF-11 socket may also be used for surface mounting the
amplifier using the two through holes.

Panel-Mount Installation Using Y92F-30 Adapter and P3GA-11 Socket
Insert the E2CA amplifier through the panel cutout. Push the
Y92F-30 adapter from the rear of the amplifier as far forward
toward the panel as possible. Then tighten the two retaining
screws. Wire the P3GA-11 socket, then push it onto the rear
of the amplifier. To release the adapter, lift the tab at the rear
of the adapter.
Several E2CA amplifiers may be panel mounted close
together using Y92F-30 adapter as shown here. When
mounting two or more amplifiers in a vertical line, arrange the
adapters so that their molded tabs are positioned on the right
and left sides. When mounting two or more amplifiers in a
horizontal line, arrange the adapters so that their molded tabs
are positioned on the top and bottom sides.
