OTTO Introduces the New HTWS Subminiature Hall Effect Thumbwheel Switch
The HTWS is a Smaller Version of OTTO's HTW and HTWM Hall Effect Proportional Output Thumbwheel Switch.

The HTWS is a subminiature Hall effect thumbwheel switch with single axis and proportional output. With a spring return-to-center, the HTWS provides a linear change in voltage output corresponding to actuator movement in either direction from center.

With its smaller size and shorter behind panel depth, it is perfect for use in grips, handheld controllers and in panels where space is limited.

The HTWS is available with eight output options, including single and dual (redundant) outputs.

The HTWS is designed for a .895” x .420” panel opening. The electronics are sealed to IP68S and an optional boot is available for added dust, sand and water protection. The HTWS offers a cycle life of three million. It is available with flying wire leads or pin connection.
