Durable rotary position sensor

26 November 2008 Switches, Relays & Keypads

Bourns has developed a new 12 mm rotary position sensor. The small and reliable new dust-proof Model 3382 provides long product life with 1 million rotational cycles and IP40 seal rating.

It is designed for a range of space-constrained applications such as navigation systems, automotive power seats and mirrors, portable electronic equipment, digital cameras, industrial equipment and controls, robotic systems and home applications including mechanical compartment systems, appliances, in-wall temperature control systems and more.

The position sensor has a shaftless, surface-mount design that operates over a temperature range from -40°C to +120°C and features independent linearity of +2%. This device is well suited for applications that require frequent adjustment where it is necessary to control a variable output such as frequency, speed, contrast, luminous intensity or volume control. The design is also a good solution for applications where a mechanical angular displacement is measured by the device’s proportional output signal.
