AL-S series limit switches feature a forced contact opening mechanism. Under abnormal conditions, the mechanism forces the contacts open to prevent pitting and fusing. Gold-plated silver contacts with scrubbing action have high reliability.
The K244 series is provided with four different kinds of contact operating actions: standard normal stroke, snap action, make-before-break, and extended stroke.
WK244 of the K244 series has bifurcated contacts, while HK244 features the scrubbing action mechanism. These limit switches can be used in the low-level circuits of 3V, 5mA.
The AL-S series limit switches feature a forced contact opening mechanism. This mechanism prevents contact welding and subsequent malfunctioning. These series therefore result in extremely dependable system controls.
FUJI K244 type limit switches have an excellent performance.
K244 limit switches employ a highly dependable and long lasting double break silver alloy contact system. These can be expected to perform more than 10 million mechanical operations and the rate of 3,000 operations per hour.
The large variety of operating modes such as standard stroke, snap-action mode, make-before-break mode, extended stroke mode, and etc. allow you to select a suitable limit switch that fully meets your needs.
K244 limit switches are widely used for industrial apparatus such as machine tools, printing machines, conveyors, automatic machines and door interlocking and similar applications. The aluminum die-cast housing can also be supplied in an oil and water proof version.
