Keep the number of connected Sensors (N) within the range of the following
equation.

It is possible, however, that the indicators may not light correctly and error
pulses (of approximately 1 ms) may be generated because the rated power
supply voltage and current are not supplied to individual Proximity Sensors.
Verify that this is not a problem before operation.
Keep the number of connected Sensors (N) within the range of the following
equation.
N × i ≤ Load reset current
Example: When an MY (24-VDC) Relay is used as the load, the maximum
number of Sensors that can be connected is 4.
<TL-NY, TL-MY, E2K-@MY@, TL-T@Y>
The above Proximity Sensors cannot be used in a series connection. If need-
ed, connect through relays.
<E2E-X@Y>
For the above Proximity Sensors, the voltage VL that can be applied to the
load when ON is V
both 100 VAC and 200 VAC.
The load will not operate unless V
This must be verified before use.
When using two or more Sensors in series with an AND circuit, the limit is three
Sensors. (Be careful of the VS value in the diagram at left.)
In general it is not possible to use two or more Proximity Sensors in parallel
with an OR circuit.
A parallel connection can be used if A and B will not be operated simulta-
neously and there is no need to hold the load. The leakage current, however,
will be n times the value for each Sensor and reset failures will frequently oc-
cur.
("n" is the number of Proximity Sensors.)
If A and B will be operated simultaneously and the load is held, a parallel con-
nection is not possible.
If A and B operate simultaneously and the load is held, the voltages of both A
and B will fall to about 10 V when A turns ON, and the load current will flow
through A causing random operation. When the sensing object approaches B,
the voltage of both terminals of B is too low at 10 V and the switching element
of B will not operate. When A turns OFF again, the voltages of both A and B
rise to the power supply voltage and B is finally able to turn ON.
During this period, there are times when A and B both turn OFF (approximately
10 ms) and the loads are momentarily restored. In cases where the load is to
be held in this way, use a relay as shown in the diagram at left.
