11 / 14 page Proximity Sensors Technical Guide ●Wiring Considerations AND/OR Connections for Proximity Sensors Note: When AND/OR connections are used with Proximity Sensors, the effects of erroneous pulses or leakage current may prevent use. Verify that there are no problems before use. Model Type of connection Connection Description DC 2-Wire AND (series connection) Keep the number of connected Sensors (N) within the range of the following equation. VS - N × VR ≥ Operating load voltage 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. OR (parallel connection) 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. AC 2-wire AND (series connection) <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 VL = VS - (Output residual voltage × Number of Sensors), for both 100 VAC and 200 VAC. The load will not operate unless VL is higher than the load operating voltage. 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.) OR (parallel connection) 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.
