The Sensors connected together must satisfy the
following conditions:
i_L + (N–1) x i = Upper–limit of control output of each
Sensor
V_S – N x V_R = Load operating voltage
N=
No. of Sensors
V_R =
V_S =
i=
Residual voltage of each Sensor
Supply voltage
Current consumption of the Sensor
i_L =
Load current
If the MY Relay, which operate at 24 VDC, is used as a
load for example, a maximum of two Proximity Sensors
can be connected to the load.
The number of Sensors connected in parallel varies with
the Proximity Sensor model.
Effects of Surrounding Metal
Shielded types:
Shielded types allow direct installation on metal plates in an em-
bedded manner without performance change. A minimum distance
of 3s_n is required between the active surface and a metallic surface
in front of the device. (Fig. 1).
For SUS shielded types the following minimum distances are re-
quired to avoid performance change (see Fig.2 and table below):

Non–shielded types:
Installation of non–shielded types in metal require the minimum di-
stances according to Fig. 3.
