EC-3000 Series and EC-3400 Series Rotary Cam Limit Switches
use interrupter discs and photocouplers instead of traditional
cams and mechanical limit switches, eliminating contact wear
and bounce. They provide on/off control of devices such as glue
guns, solenoids, air cylinders, or relays on shaft-driven machin-
ery. Electronic Cam Limit Switches can be used as stand-alone
switches, or they can be interfaced to programmable logic con-
trollers (PLC’s) or other logic circuitry.
Although generally used for applications which do not require
setpoint adjustment for speed changes or product changeover,
EC-3000 Series and EC-3400 Series switches can accommo-
date multiple setpoint schemes by assigning groups of interrupt-
ers to different product configurations. For product changeover,
simply activate the appropriate group of interrupters.
Typical applications for EC-3000 Series and EC-3400 Series
switches include cartoners and case packers, palletizers, gluing
machines, high-speed presses, automatic assembly, pick and
place equipment, and similar machinery.
