AutomationDirect has added Nitra CPS9E series cylinder position switches, which are compact general-purpose switches designed to detect the position of a pneumatic cylinder's magnetic piston. This feedback can be used by a control system to determine cylinder position, cycle count and to confirm operation. These switches are manufactured specifically to fit into extruded or machined 1/4-in. 60° dovetail slots. They are superior to reed switches since they use solid-state technology with no moving parts for a longer life. They are available in PNP or NPN logic, with a normally open output, and a flying lead pigtail or a 3-pin M8 electrical connection with a 90° cable exit.
