C&K Components has designed a new series of IP67-sealed SMT key switches for harsh environment applications.
Designated the K12S series, the robust key switches are available with LED backlighting in a wide selection of colours, and detect versions.
Featuring excellent tactile feedback, the highly reliable devices provide a life cycle of more than 1 million actuations, making them ideal for demanding conditions often found in automotive, motorcycle, off-road transportation, industrial and medical applications.
The K12S series features abuse-proof contacts, 100 N overload resistance and self-cleaning golden contacts. The key switches offer an actuation force range of 1,5 N to 15 N, with a total travel of 1,5 mm. They also maintain a wide range of contact arrangements (NO/NC and SPST/DPST). Customisation options are available, including detect versions.
The switches feature a maximum power rating of 3 W d.c. and a minimum/maximum voltage of 2 V–30 V d.c., with a minimum/maximum current rating of 10 μA to 100 mA. The operating temperature ranges from -40°C to
+85°C. The K12S series is also available in an IP40-rated package for less demanding applications.
The RoHS-compliant and halogen-free switches’ advanced design offers customers the flexibility to tailor force values, actuation travel options and provide double-pole single-throw (DPST) custom solutions to meet specific application requirements.
