Loads with Large Surge Currents (E2E-X@T@)
If a load with a large surge current is connected, such as a relay, lamp, or motor, the surge current may cause the load short-circuit protection
circuit to operate, resulting in operating errors.
● Mounting
Tightening Force
Do not tighten the nut with excessive force.
A washer must be used with the nut.

Note: 1. The allowable tightening strength depends on the distance from the edge
of the head, as shown in the following table. (A is the distance from the
edge of the head. B includes the nut on the head side. If the edge of the
nut is in part A, the tightening torque for part A applies instead.)
2. The following strengths assume washers are being used.

Connecting a DC 2-Wire Proximity Sensor to a PLC (Programmable Controller)
Required Conditions
Connection to a PLC is possible if the specifications of the PLC and the Proximity Sensor satisfy the following
conditions. (The meanings of the symbols are given at the right.)
1. The ON voltage of the PLC and the residual voltage of the Proximity Sensor must satisfy the following.
VON ≤ VCC− VR
2. The OFF current of the PLC and the leakage current of the Proximity Sensor must satisfy the following.
IOFF ≥ Ileak
(If the OFF current is not listed in the PLC’s input specifications, take it to be 1.3 mA.)
3. The ON current of the PLC and the control output of the Proximity Sensor must satisfy the following.
IOUT (min.) ≤ ION ≤ IOUT (max.)
The ON current of the PLC will vary, however, with the power supply voltage and the input impedance, as
shown in the following equation.
ION = (VCC − VR − VPC)/RIN
Example
In this example, the above conditions are checked when the PLC Unit is the C200H-ID212, the Proximity
Sensor is the E2E-X7D1-N, and the power supply voltage is 24 V.
1. VON (14.4 V) ≤ VCc (20.4 V) − VR (3 V) = 17.4 V:OK
2. IOFF (1.3 mA) ≥ Ileak (0.8 mA):
OK
3. ION = [VCC (20.4 V) − VR (3 V) − VPLC (4 V)]/RIN (3 kΩ) = Approx. 4.5 mA
Therefore, IOUT (min.) (3 mA) ≤ ION (4.5 mA): OK
Connection is thus possible.
VON: ON voltage of PLC (14.4 V)
ION: ON current of PLC (typically 7 mA)
IOFF: OFF current of PLC (1.3 mA)
RIN: Input impedance of PLC (3 kΩ)
VPC: Internal residual voltage of PLC (4 V)
VR: Output residual voltage of Proximity Sensor
(3 V)
Ileak: Leakage current of Proximity Sensor
(0.8 mA)
IOUT Control output of Proximity Sensor (3 to
100 mA)
VCC: Power supply voltage (PLC: 20.4 to 26.4 V)
Values in parentheses apply to the following PLC
model and Proximity Sensor model.
PLC: C200H-ID212
Sensor: E2E-X7D1-N
