EC-3000 Series and EC-3400 Series Rotary Cam Limit Switches available from Veederline 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 machinery.

Electronic Cam Limit Switches can be used as stand-alone switches, or they can be interfaced to programmable logic controllers (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 accommodate multiple setpoint schemes by assigning groups of interrupters to different product configurations.

For product changeover, simply activate the appropriate group of interrupters.

All EC-3000 Series units are housed in NEMA 12 enclosures. All EC-3400 Series units are housed in NEMA 4X stainless steel enclosures.

All units have right, left, or double-ended shaft extensions with a 606 Woodruff Key provision; Nema 4X models have a double-ended stainless steel shaft.

The cover plate on the EC-3400 Series units is secured with clamps to avoid contamination. Five standard EC-3000 Series and four standard EC-3400 Series models are available.

Model outputs standard shafts:

  • EC-3004/EC-3404 4 right, left or double
