Notes:
1. When you specify custom types (custom-made), new tooling and jigs, and/or equipment may be required. It will be necessary to confirm your
estimates of quantity and development schedule as accurately as possible.
2. Please inform us if you designate your own part number.
✽ Previous notations for potentiometer shape “Stand-up type” (Shaft is parallel to PWB.) and “Lay-down type” (Shaft is vertical to PWB.) – have
been changed in this edition to “Horizontal type” or “Side-adjust type” (Shaft or knob is parallel to PWB.) and “Vertical type” or “Top-adjust type”
(Shaft or knob is ver tical to PWB.).
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
Should a safety concern arise regarding this product, please be sure to contact us immediately.

4. For use in equipment for which safety is requested
Application Notes
Although care is taken to ensure encoder quality,
infe ri or characteristics, short circuits, and open
circuits are some problems that might be generated.
To design a set which places maximum emphasis
on safety, review the affect of any single fault of a
encoder in advance and perform virtually fail-safe
design to ensure maximum safety by:
1. preparing a protective circuit or a protective
device to improve system safety, and
2. preparing a redundant circuit to improve system
safety so that the single fault of a encoder does
not cause a dangerous situation.
When using our Encoders, please observe the following
cautionary items to prevent dangerous accidents and
deterioration of performance.
1. Prohibited items and notes in design stage
1. Soldering conditions
W hen per forming solder dipping, check the
soldering conditions according to the Individual
“Product Specifi cations,” because the conditions
vary from product to product.
Do not wash an encoder after solder dipping
because flux may invade the encoder, resulting in
contact failure. Avoid use of jumper cables near the
encoders because flux may get to them.
2. Shaft rotation wobble
If the shaft is long, the rotation wobble increases in
proportion to its length. To secure the quality of a
set, we recommend use of the types with a bushing.
3. Operating temperature conditions
Tactile feeling in operation is given serious
consideration, and rotation torque increases
under low temperatures (below –10 °C) depending
on the product. If a encoder is expected to be used
under low temperatures, specify this in advance.
5. For actual use, be sure to refer to “Product
Specifications for information.”
2. Prohibited items and notes on handling
1. Chemical resistance
Before using a potentiometer with an insulated shaft,
be sure to check the reactivity of the shaft with any
chemicals to be used.
2. Storage conditions
Do not store the encoders under high temperatures
and /or high humidit y, or in a location where
corrosive gas may be generated. Store the encoders
at room temperature and room humidity in a packed
condition. Use them within a maximum of 6 months.
Check the date of manufacture on the package box
and apply the “fi rst-in-fi rst-out” rule. If unpacked
encoders must be stored as inventory, store them in
a polyethylene bag to keep out air.
3. Prohibited items on fire and smoking
1. Absolutely avoid use of a encoder beyond its rated
range because it may cause a fire.
If misuse or abnormal use may result in conditions
in which the encoder is used out of its rated
range, take proper measures such as current
interruption using a protective circuit.
2. The grade of nonfl ammability for resin used in
encoders is “94HB,” which is based on UL94
Standards (fl ammability test for plastic materials).
Prohibit use in a location where a spreading fi re
may be generated or prepare against a spreading
fire.
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
Should a safety concern arise regarding this product, please be sure to contact us immediately.
