Supplied in dust proof enclosures with carbon resistive elements, 10 mm PT10 and 15 mm PT15 feature stepped outputs (constant voltage zones). Combining constant value zones with detents allows engineers to align same voltage values with each of detent stops when rotating control both forward and backward. Depending on model, performance characteristics are available with mechanical rotational angles from 10° up to 265° ±5° and electrical rotational angles of up to 240° ±20°.
