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

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 embedded 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 required to avoid performance change (see Fig.2 and table below):
