Position sensor, linear displacement sensor shipments to increase

Natick, MA— Similar to other industrial automation markets, prospects continue to brighten for proximity and linear displacement sensor markets in North America, according to a recent research by Venture Development Corp. (VDC). The analyst firm’s report adds that photoelectric proximity sensors and laser-based sensors are two of the fastest growing segments.

VDC anticipates positive growth in North American markets for these sensors through 2007, based on improving health of the U.S. economy and increasing implementation of these sensors for monitoring and control in many products and equipment. Shipments for proximity sensors to North America are expected to grow at a 4.7% compound annual growth rate (CAGR) from $617.2 million in 2004 to $708.5 million in 2007.

Likewise, shipments of linear displacement sensors are projected to increase at a 4.3% CAGR from $334.9 million in 2004 to $380.1 million in 2007. The largest share of each sensor type will go to industrial automation applications. Other uses include HVAC, medical, metrology, military/aerospace, office automation, printing, security equipment, and automotive vehicles. VDC adds that use of position sensors augments performance with improvements in accuracy, efficiency, enhanced functionality, faster operation, higher productivity, and better quality control.

The report adds that optical-based devices will grow the fastest. North America’s market for photoelectric proximity sensors is forecast to increase at an overall 6.1% CAGR through 2007. Photoelectric proximity sensors use several types of light sources.

The fastest growing areas are infrared and laser-based products. Infrared sensors efficiently produce a strong beam that is desirable for long-range sensing. The North American market for laser systems is expected to be the fastest growing among the linear displacement sensor products at an 8.5% CAGR through 2007. Laser proximity and linear displacement sensors have long-range and small-target capabilities.
