D4C
Sealed, Compact, and Slim-bodied Switch
Offers Choice of Many Actuators
• Liquid- and dust-resistance conforms to IEC IP67 standard.
• Triple-sealed construction:
Plunger section sealed via nitrile rubber packing seal and diaphragm; switch section sealed via nitrile rubber cap; cable entrance sealed via encapsulating material.
• Standard cable (S-FLEX VCTF) in 2-, 3-, or 5-meter lengths offers high flexibility with outstanding oil and extreme temperature
resistance.
• Low temperature models are available.
