Frequently asked question (FAQ)

Question: Is the autoswitch magnet for the CU/CUK Series built-in as standard?
Answer: Add "D" to the CU part number to have a magnet built in (ex. CDU10-20D).
Note that φ16 and up with built-in magnet have a longer total length (S and Z dimensions) than the standard dimensions (without magnet). For details, see the catalog.
Note 1) The CDU/CDUK single acting pull types have longer body dimensions than standard from φ20 up.
Note 2) The CDUJ Series have longer body dimensions than standard from φ6 up.
Question: What are the selection criteria for autoswitches that are compatible with the CUJ/CU/CUK Series?
Answer: Upon consideration of
(1) Mounting: Direct (groove) mounting only;
(2) Load voltage: DC or AC and voltage;
(3) Switch contact: Wet or dry;
(4) Two-wire or three-wire;
(5) Environment: Improved water resistance;
(6) Diagnostic display (two-color display);
(7) Lead wire length: 0.5, 1, 3, or 5 m
etc. as conditions for selection, please select a switch from those in the catalog.
