Miller SRL2-M Series
Rodless Cylinders

On M25 and/or M2WV5 switches, the leakage current increases
based on the number of connections. When one switch turns on
and off, as the voltage at both ends of the switch connected in
parallel drops below the load voltage range down to internal voltage
drop value when switch is turned on, other switches will not turn
on. Therefore, check the specified input of the programmable
controller regarding the connection load before use. M35 and
M3WV5 switches have a small leakage current (under 10µA) so
multiple connections will usually not present a problem or cause
the lamp to fade or stay off.

Avoid using switches near a strong magnetic field or strong current
(large magnet, spot welding machine, etc.). When cylinders with
switches are mounted close to each other in parallel, or when
magnetic material moves near the cylinder, they could cause
interference and affect switch operation.

Minimum bending radius of lead wires should be 3/8". Ensure that
no bending or tension stresses are continuous on the wires. For
moving portion, use wiring similar to that used on robots.

Minimum bending radius of lead wires should be R9 or more. Ensure
that no bending or tension stresses are continuous on the wires. For
moving portion, use wiring similar to that used on robots.

Avoid using a load that exceeds the maximum contact capacity of
the switch. In the case of a lower current than the rated current
value, the M0 switch lamp may not light.

When using an inductive load, such as a relay, etc., be sure to set
the protection circuit as shown in Fig. 1 and Fig. 2. Also, if lead wire
is longer than that specified in Table 1, set protection circuit as
shown in Fig. 3 and Fig. 4.

Connect the lead wire of the switch with load in series type
connection. Do not connect it directly to a power source. In the
case of the M05 switch the following will apply:

(1) When using for DC, connect the black (white) wire to positive,

and blue (black) wire to negative. If the wires are reversed, the
switch will work but the lamp will not light.

(2) When connecting to an AC relay or programmable controller

input, using half wave rectification, the switch may not light. If
this happens, it can be corrected by connecting the switch lead
wires to the opposite polarity.

If more than one M05 switch is wired in series, value of voltage drop at
switches are the total of all the switches connected. In order to ensure
its operation, use one M05 switch and use M55 for the others and the
voltage drop will be limited to that of one M05 switch (about 2.4V).
The lamps will light only when all the switches are on.

Any number of switches can be used in parallel connections, but in the
case of the M0 switch, the lamp might be dimmer or not on at all.
