D5A
D5A
When a limit switch type is used, apply grease to the dog to
reduce friction between it and the plunger. Do not apply grease to
pin plungers, otherwise the grease may stick to the contacts or
generate gas that may cause contact failures.
Be sure to use dogs made of hard materials for bevel or top
plungers and apply grease to the surface of the dogs. The hard-
ness (Hv) of a bevel plunger is 2,000 or over, for which it is recom-
mended that a dog that has an Hv value of 1,000 or less be used.
Do not fail to provide a stopper so as to prevent the enclosure of
the D5A from being used as the stoppers.
Attach an appropriate cover for the protection of the D5A from
machining oil or cuttings. No protective cover is, however, pro-
vided together with the Switch.
Exercise care that excessive force is not applied to the ceramic
plunger of M5, M8, or slim type.
If the possibility exists that strong shock may be applied to the
plunger when the Switch is being mounted, use a protective cap.
The plunger may not release if it is depressed with too great a
force. Set its stroke by referring to the OT value indicated in Oper-
ating Characteristics.
Do not mount the Switch with its nameplate facing downwards
(i.e., in the direction of gravity), otherwise the oil drain hole will not
work effectively.
