The EFC combines a photoelectric sensor with a timing control that limits compressed air use by turning it off when no part is present.
For most plants, the air compressor uses more electricity than other equipment in the facility. One simple blowoff, cooling or drying operation that uses compressed air can easily waste thousands of those electricity dollars per year if not properly controlled. The EFC reduces compressed air costs by turning on the air only when a part is present and provides just enough air to complete a specific task or operation.
The timing control of the EFC permits easy tuning to the application requirements with numerous valve operating modes and timing delays. The compact photoelectric sensor has a sensitivity adjustment and detects objects up to 1 metre away. The sensor provides superior immunity to noise and inductive loads that are common to industrial environments and installs easily in tight spaces with the supplied mounting bracket.
The EFC has an easy electrical connection for voltages from 100V to 240VAC (50/60Hz) that is appropriate for applications throughout the world. The NEMA 4 polycarbonate enclosure of the EFC is suitable for a wide range of applications including those in wet locations. The timing control unit and photoelectric sensor are equipped with a 2.74 metre power cord.
Three models of the EFC are offered that include the timing control, photoelectric sensor and choice of a 40, 100 or 200 SCFM solenoid valve.
