Miniature Sensors offer 1.0 m sensing range.

Press Release Summary:




Series VS4 Opposed-Mode self-contained sensors utilize optically correct lens, which redirects visible red sensing beam 90° off internal circuit board, sending light out narrow side of sensor. Designed for presence sensing inside machinery, 10-30 Vdc sensors have max output rating of 50 mA. Constructed of thermoplastic with polycarbonate mounting holes and lenses, sensors include noise suppression and meet IEC IP67 and NEMA 6 standards.

Extremely Low-Profile Miniature Sensor Features Powerful 1.0M Sensing Range and Advanced Noise Suppression



Minneapolis, MN-December 20, 2002-Banner Engineering Corp. has
announced new VS4 Series Opposed-Mode self-contained miniature sensors. Designed for precision sensing in tight confines, the VS4's horizontal mounting capability and extremely small size make it ideal for applications previously only accessible by remote or fiber optic models. Despite their tiny size, these self-contained sensors utilize a unique optically correct lens which through a periscope-like concept, redirects the visible red sensing beam 90 degrees off the internal circuit board, sending light out the narrow side of the sensor. This provides a
powerful 1.0 m (39") sensing range and easy alignment for machine mounting.

The VS4's unique overmolded housing eliminates traditional weld seals thus completely coating and sealing the inner components and cable entries of the sensor from contamination by dirt or moisture. At the same time, this technique yields an extremely thin sensor at just 4.75 mm (0.19") thick by 25.0 mm (0.99")
high and 12.2 mm (0.48") wide. Inside the tiny housing, the VS4's advanced circuitry delivers powerful, precision sensing performance and the entire electronic assembly is shielded from noise through a special metalized coating process.

Designed for presence sensing inside machinery such as electronic component handling equipment, miniature conveyor transportation mechanisms and document handling equipment, the VS4 also may be used to perform simple inspections for high caps, open box flaps or skewed material. Semiconductor manufacturing applications include inspection of skewed, missing or protruding wafers and wafer mapping.

LED indicators on the sensors provide constant operating status information. The steady green LED indicates Power ON; it flashes to indicate output overload. The yellow LED indicates Output On; it flashes to indicate marginal excess gain sensing conditions.

The 10 to 30V dc VS4 Series Opposed-Mode Sensors have a maximum output rating of 50 milliamps. Models are available for light operate (N.O.) or dark operate (N.C.), with a choice of NPN (current sinking) or PNP (current sourcing) outputs. The tough and tiny sensors tolerate vibration, mechanical shock, and
washdown. Internal circuitry guards against false pulse on power-up, continuous overload, and short circuit of outputs.

Constructed of durable black thermoplastic with polycarbonate mounting holes and lenses, VS4 sensors meet IEC IP67 and NEMA 6 standards and operate in temperatures of -20°C to +55°C (-4°F to +131°F). The sensors are available with an integral 2 m (6.5') cable, or a 3-pin pigtail Pico-style quick-disconnect fitting.
All models include M2 stainless steel mounting hardware for easy installation. Optional beam shaping apertures are also available. The VS4 sensor is a high quality, low-cost replacement for remote and fiber optic devices. List prices begin at $83.00 for an opposed-mode pair.
