(2) Do not use in an environment where the auto switch will be continually exposed to water.
Although auto switches satisfy IEC standard IP67 construction, do not use auto switches in
applications where they will be continually exposed to water splash or spray. This may cause
improper insulation or malfunction.
(3) Do not use in an environment with oil or chemicals.
If auto switches are used in an environment with containing coolant, cleaning solvent, various
oils or chemicals, even for a short period of time, this may adversely affect the auto switches,
resulting improper insulation, malfunction due to the swelling of potting resin, or hardening of
lead wires.
(4) Do not use in an environment with temperature cycles.
If temperature cycles other than normal temperature changes are applied, this may adversely
affect the insides of the auto switches.
(5) Do not use in an environment where there is excessive impact shock.
<Reed>
When excessive impact (300m/s
contacts will malfunction and generate or cut off a signal momentarily (1ms or less). If further
excessive impact is applied, the reed auto switch may break. Depending on the environment, a
solid state auto switch may be required.
(6) Do not use in an area where surges are generated.
<Solid state>
If there is an equipment unit (electromagnetic lifter, high-frequency induction furnace, motor,
radio, etc.) that generates large surges or electromagnetic waves around cylinders or actuators
with solid state auto switches, this may cause the circuit element inside the auto switch to
break.
(7) Avoid the accumulation of iron waste or close contact with magnetic substances.
If too many iron particles, such as cutting chips or spatters, accumulate around a cylinder or
actuator with auto switches, or if a magnetic substance (attracted by a magnet) is put close to a
cylinder or actuator with auto switches, the magnetic force inside the cylinder or actuator may
weaken, causing the auto switch to malfunction.
(8) Do not use in direct sunlight.
(9) Do not mount the product in locations where it is exposed to radiant heat.
(10)Take appropriate measures against the lightning surge on the equipment side as the
auto switches do not have any lightning surge resistance specified in the CE marking.
Maintenance
Warning
(1) Removal of equipment, and supply/exhaust of compressed air.
Before any machinery or equipment is removed, first ensure that the appropriate measures are in
place to prevent the fall or erratic movement of driven objects and equipment, then cut off the electric
power and reduce the pressure in the system to zero. Only then should you proceed with the removal
of any machinery and equipment.
When machinery is restarted, proceed with caution after confirming that appropriate measures are in
place to prevent actuators from moving suddenly.
(2) Do not touch a terminal during energizing.
Touching a terminal during energizing may cause electric shock, malfunction, or auto switch
breakage.
