Basic Linear Sensors Type 1


Type 1 sensors are robust, precise and simple. They are also narrow - 10mm wide - which means they can fit in tight spaces. Standard sensors are available from 25mm to 300mm measuring length.
25mm, 50mm, 100mm, 150mm and 200mm Type 1 linear sensors
A single CAM204 Central Tracking Unit (CTU) chip can operate up to 4 Type 1 sensors, including a mix of linear and rotary.
