stabilised and smoothed direct voltage, consider residual ripple.
Utilisation category: AC-140, DC-13.
Hysteresis: difference between switch-on and switch-off points.
Short-circuit protection: pulsed protection, may cut in with incandescent lamps or low resistance loads.
Standard target: 1mm thick, square-shaped steel plate, side length equal to sensing face diameter or 3xSn.
Product standard: IEC 60947-5-2.
Repeatability: max 10% of Sr.
Leakage current: internal supply current for 2-wire units, flows through load when output is blocked.
Switch point drift: shift due to ambient temperature changes.
Switching frequency: damping with standard target at half Sn, ratio 1:2.
Protection rating: IP68, IP69K.
Current consumption: internal supply current for 3-wire DC units.
Transport and storage: -40°C to max ambient temperature, 50% RH at +70°C, 5-year shelf life.
Degree of soiling: designed for degree 3.
Maintenance, repair, disposal: no maintenance needed, only manufacturer can repair, dispose environmentally friendly.
Intended use: ensure suitability for application, particularly in hazardous areas or adverse environments.
Operating principle: LC resonant circuit, eddy current losses in conductive materials for switching signal.
Glossary: active zone, output function, rated insulation voltage, rated short-circuit current, power-on delay time.
Sensing range: Sn, Sr, Sumin, Sumax, Sa, nominal and real sensing ranges, useful and reliable sensing ranges.
Correction factors: for different materials, target size influence, lateral approach and ranges.
Installation: electrical connection, use miniature fuse, check safe functioning after short circuit, series and parallel connections.
Minimum clearance: for installing units side-by-side, flush and non-flush mounting instructions.
