NK Technologies' ASC Series Switches are designed for improved safety and startup efficiency

NK Technologies' ASC Series Switches are designed to be precision calibrated at the factory. ASC switches are built to combine a current transformer, microprocessor-based signal conditioner and limit alarm contact for use in status monitoring or proof of operation applications. ASC switches are made for: proof of flow, conveyor jam and overload detection, multiple section conveyor interlocking, and control of lighting circuits or electrical heaters.

Current operated switches are self-powered. ASC switches provide a magnetically isolated N.O. or N.C. solid state output for control circuits rated up to 135 VAC or VDC. The set trip point (from 2 to 150 amps) is precision calibrated at the factory and designed for improved safety and startup efficiency. Switch response time is 120 msec. An LED indicator provides quick visual confirmation of contact status.

ASC switches are offered in two configurations: a solid-core case with a Ø0.74” (19 mm) thru-hole sensing aperture, or; a split-core case with a hinged opening to provide a 0.85” (21.6 mm) square sensing aperture. Package dimensions of both configurations are approximately 3.5” W x 2.25” H x 1.2” D (90 x 57 x 5 mm). Built-in mounting feet are made to accommodate two-screw panel mounting, or units can attach with optional DIN rail brackets. The switch casing is made to a UL94 VO flammability rating. Operating environment is rated for -4 to 122°F (-20 to 50°C) 0-95% relative humidity non-condensing. All units are designed to meet UL, CUL and CE Approval.
