Output Circuit Protection
Series Connection
Connection to Programmable Controller (Sequencer)
• When connecting and using an inductive load (relays,
solenoid valves), as surge voltage occurs with the switch
off, be sure to wire a protection circuit as shown in Fig. 3.
• When connecting and using a capacitor load, as in-rush
current occurs with the switch on, be sure to wire a
protection circuit as shown in Fig. 4.
• When lead wire is more than 10m long, be sure to wire a
protection circuit as shown in Fig. 5, 6 (for M2, M2WV) or
Fig. 7 (for M3, M3WV).
Fig. 3. Example where inductive load is used with diode. Use diode Hitaachi
V06C or equivalent.
Fig. 4. Example where capacitor load is used with resistance (R). Resistance (R)
should exceed the value from the formula.
Fig. 5. Choke coil L= hundreds of H - several mH, with high-frequency
characteristic. Connection should be within 2m of switch.
Fig. 6. In-rush current resistance R equals as much resistance as load circuit
side permits. Connection should be within 2m of switch.
Fig. 7. Power source noise absorption circuit C1 = 20-50 µF electrolytic
capacitor (more than 50V of allowable pressure).
C2 = 0.01-0.1 µF. Ceramic capacitor R1 = 20-30 Ohms. In-rush current
resistance R2 equals as much resistance as load circuit side permits.
Connection should be within 2m of switch.

Connection depends on type of programmable controller.
Conneciton should be as shown n Fig. 8-12.

(1) If more than one M25 and/or M2WV5 switches are wired in series,
the total amount of voltage drop is the sum of all the switches connected.
As voltage at load side is power voltage minus the sum of voltage fall at
switches, check your programmable controller, as being a load, with its
specified input to determine maximum number of connections.
(2) If more than one proximity switch of the 3-wire type are wired in
series, the value of the voltage drop at switches is the total sum of
voltage fall of all the switches connected. As current flowing in the
switches is the sum of the power consumption of all of the switches
connected and load current, as shown below, check the specified load
of switches so that it does not exceed the maximum load current of
switches, and determine the mazimum number of connections.
(3) Lamp is on only when all the switches are on.
