Compact limit switch excelling in compact size, thin and high seal properties.
[Features]
· Approved by EN (TÜV), UL, CSA, CCC standard. (ask your manufacturer for information on approved models)
· High sealing property compliant with IEC Standard IP67.
· The plunger has a seal packing, a diaphragm and the built-in switch has a protective cap and a triple seal structure.
· 3 m and 5 m cords are used as a standard. Series with cords certified by UL and CSA standards.
· Plunger type enables multiple mountings.
· A series of LED indicator lights (red) is made to facilitate confirmation during operation. (Lights up when not operating as a standard)
· VCTF oil-resistant cord type and pre-wired type products confirm with CE marking. (However this is applicable to the Standard type only)
