Miniature sensors

Banner Engineering has available the VS4 series opposed-mode self-contained miniature sensors.

Designed for precision sensing in tight confines the horizontal mounting capability and small size make it suitable for applications previously only accessible by remote or fibre optic models.

Despite their tiny size, these self-contained devices used an optically correct lens which through a periscope-like concept, redirects the visible red sensing beam 90° off the internal circuit board, sending light out on the narrow side of the sensor.

This provides a 1.0 m sensing range and easy alignment for machine mounting.

The overmoulded housing eliminates traditional weld seals completely coating and sealing the inner components and cable entries of the sensor from contamination by dirt or moisture.

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.

The 10 to 30 VDC sensors have a maximum output rating of 50 mA. Models are available for light operate (NO) or dark operate (NC), with a choice of NPN (current sinking) or PNP (current sourcing) outputs.
