Koganei YMDA Series, Compact & Direct Mounting

4

Always read these precautions carefully before use.

CAUTION

When mounting the product, leave room for adequate working 
space around it. Failure to do so will make it more difficult to 
conduct daily inspections or maintenance, which could eventu-
ally lead to system shutdown or damage to the product.

Do not bring any magnetic media or memory within one meter 
[3.28 ft] of the product. Doing so creates the risk of damage to 
data on the magnetic media due to magnetism.

The sensor switch should not be used in a location where high 
current or magnetic field is generated. This may cause the 
machine to malfunction.
Also avoid using magnetic material for any parts used for 
mounting. Doing so creates the risk of magnetism leakage that 
causes malfunctions.

Do not bring the product close to magnetized body. Bringing 
the product close to magnetized body or the location where 
high magnetic field is generated can magnetize the main body 
or table, resulting the malfunction of sensor switches or defec-
tive operation due to attachment of the iron powder.

Make absolute sure that sensor switches of other companies 
are not used for this product.
Failure to do so can lead to malfunctions or runaway 
operations.

Do not scratch, dent, or deform the actuator by climbing on the 
product, using it as a scaffold, or placing objects on top of it. 
Doing so creates the risk of damage to or breakage of the 
product, resulting in operational shutdown or degraded 
performance.

Always post an "operations in progress" sign for installations, 
adjustments, or other operations, to avoid unintentional 
supplying of air or electrical power, etc. Unintended power or 
air supply can cause electric shock or sudden cylinder 
movement, creating the risk of personal injury.

Do not apply excessive load to the cords, such as the lead 
wires of sensor switches mounted on the cylinder, in such 
manner as pulling, carrying by hands or placing heavy object 
on the cords. Doing so may cause the leak current or defective 
continuity, leading to fire, electric shock or malfunctions.

When the pressure is increased by external force, make sure 
to attach the relief equipment or any other means not to 
exceed the specified operating pressure of the cylinder. 
Pressure exceeding the specified operating pressure may lead 
to malfunction and breakdown.

When the machine has been idle for over 48 hours or is in first 
operation after storage, it is possible that the contacting parts 
may have become stuck, leading to operation delays or 
sudden movements. In initial operation, be sure to perform trial 
operation to check whether the machine works properly.

Never use the product in direct sunshine-suffered location like 
beach, near mercury lamp, or near a product likely to produce 
ozone. Deterioration of rubber parts caused by ozone may 
reduce the performance and function or stop the function.

Because KOGANEI products may be used under a wide 
variety of conditions, decisions concerning conformance with 
a particular system should be made upon the careful 
evaluation by the person in charge of system design. 
Assurances concerning expected system performance and 
safety are the responsibility of the designer who decides 
system conformity. Be sure to use the latest catalogs and 
technical materials to study and evaluate specification details, 
to consider the possibility of machine breakdown, and to 
configure a system that ensures fail-safe safety and reliability.

Do not use in locations that are subject to direct sunlight 
(ultraviolet rays), in locations with dust, salt, or iron particles, 
or in locations with media and/or ambient atmosphere that 
include organic solvents, phosphate ester type hydraulic oil, 
sulfur dioxide, chlorine gas, acids, etc. Such uses could lead to 
early shutdown of some functions, a sudden degradation of 
performance, and a reduced operating life. For details on 
materials used in the product, refer to the description of major 
parts.

Always observe the following items.
KOGANEI shall not be held responsible for any problems that 
occur as a result of these items not being properly observed.

2.

 Never attempt inappropriate disassembly or assembly of the prod-

uct relating to basic construction, or its performance or functions.

KOGANEI shall not be held responsible for any problems that occur 
as a result of these safety precautions not being properly observed.

Others

ATTENTION

Whenever considering use of this product in situations or 
environments not specifically noted in the "catalog" or "instruction 
manual", or in applications where safety is an important requirement 
such as in aircraft facilities, combustion equipment, leisure equipment, 
safety equipment, and other places where human life or assets may 
be greatly affected, take adequate safety precautions such as allowing 
plenty of margin for ratings and performance, or fail-safe measures.
Be sure to contact KOGANEI before use in such applications.

Always check the "catalog" and other reference materials for 
product wiring and piping.

Moving parts of machine and devices should be isolated with a 
protection cover so as not to be directly contacted by human body.

Do not configure the control that may cause a workpiece to 
drop when in power outage.
Be sure to configure the work/table-drop prevention control for 
the case of power outage or emergency stop of the machine.

When handling the product, wear protective gloves, safety 
glasses, safety shoes, etc., as required.

When the product can no longer be used or is no longer 
necessary, dispose of it appropriately as industrial waste.

Pneumatic equipment can exhibit degraded performance and 
function over its operating life. Always conduct daily inspections of 
the pneumatic equipment, and confirm that all requisite system 
functions are satisfied, to prevent accidents from happening.

For inquiries about the product, consult your nearest KOGANEI 
sales office or KOGANEI overseas group. The addresses and tele-
phone numbers are shown on the back cover of this catalog.
