Thank you, Dr. Bob. Good evening, everyone. I'm pleased with the results we reported tonight for the first quarter of 2012. They were slightly ahead of our expectations.
Revenue grew 4% over the first quarter of 2011, despite significantly lower revenue from the semiconductor and electronics capital equipment market, resulting from that market's downturn. The broad range of industries that we serve in the factory automation and surface inspection markets drove growth in the first quarter.
From a product standpoint, ID products continue to be our leading performer, increasing 29% year-on-year. Gross margins remained very strong at 75%, reflecting the value of the Cognex customers recognize in our technology. Operating margins of 23% tracked with our long-term target despite the investments we made in new product development and sales force expansion to drive future growth. And we reported earnings of $0.33 per share, an increase over the $0.32 reported for the prior year's strong first quarter.
Now let's turn to the details of the quarter. Revenue from the factory automation market was $59 million and accounted for 76% of total revenue. This level represents growth of 14% year-on-year. As expected, factory automation revenue declined by 5% on a sequential basis due to seasonality we typically see at the start of a new year.
From a geographic perspective, Asia was our best performer during the first quarter in terms of percentage growth. Factory automation revenue from Asia increased 31% year-on-year and 12% from the prior quarter. Although a slowdown in the consumer electronics industry has cooled our growth rate, especially in Greater China, Asia is still growing faster than the rest of our business. On a sequential basis, growth was led by strong sales in Korea.
Sales to the Japanese factory automation market increased 21% over the first quarter of 2011. While spending on automation equipment is sluggish in Japan and the consumer electronic slowdown has dampened growth, our business continues to grow well through the Mitsubishi channel following the setback of last year's earthquake and tsunami.
In Europe, our factory automation business held up well, considering the region's economic news, increasing 12% year-on-year. On a constant currency basis, the growth was 16%. Strong performance in automotive, consumer products and food and beverage offset significantly lower revenue from solar customers.
And factory automation revenue from the Americas increased 8% over the first quarter of 2011. We saw good forward momentum in the broad factory automation market, with particularly strong performance in automotive.
Revenue from the semiconductor and electronics capital equipment market was $6.7 million in the first quarter. This represents a decrease of 47% year-on-year, or a reduction of $6 million. SEMI revenue increased by 28% on a sequential basis, which was a positive development. It appears the downturn has bottomed out and the market is beginning to recover.
In the surface inspection market, first quarter revenue was $11.6 million. This represents an increase of 20% year-on-year and a decrease of 28% from the record level reported for the prior quarter. Surface inspection revenue can be lumpy due to the timing of deliveries and installations and the impact of revenue deferrals. Demand for our surface inspection systems remains solid in both metals and paper, our main vertical industries.
We are pleased that the investments we have made in new product development are helping Cognex grow revenue despite challenging conditions in certain industries and geographic regions. The new Cognex products hitting in the market today are more powerful and easier to use than ever before. One example is the DataMan 300, the latest addition to our lineup of industrial ID readers. Incorporating our groundbreaking new Hotbars technology, the DataMan 300 is a self-configuring barcode reader that can read the most difficult 1D and 2D codes as they are presented at any angle on high-speed lines. This reliable and versatile ID reader is opening new opportunities for Cognex in both manufacturing and logistics.
In the first quarter, we also introduced OCRMax, an exceptional optical character-reading software product for our In-Sight and VisionPro platforms. OCRMax is a very powerful, accurate, fast and easy-to-use tool for reading and verifying character strings, such as vehicle identification numbers on automobile parts and date and lot codes on aspirin bottles, soup cans and cosmetic packages as they move on factory conveyors.
OCRMax can handle character variations, text skews, proportional fonts and variable string lengths easily and at the highest read rate. Customers are using OCRMax in applications that until now were extremely difficult for machine vision to perform.
OCRMax and Hotbars are 2 examples of the software innovation for which Cognex is recognized. They are highly advanced technologies, but difficult applications, that enable us to maintain high margins and win new customers in automotive, food and beverage, pharmaceuticals, consumer products, logistics and other target industries.
Our sales force expansion is also contributing to top line growth. One reason for our momentum is the additional sales engineers we have added over the past 24 months and the quality of the people we have hired. We are building our numbers of sharp, highly motivated sales engineers who are committed to Cognex.
Further additions to engineering and sales are planned for 2012, although at a slower pace than in 2011. The consistent investment we make in our business reflects the confidence we have in our plans for growth.
For the second quarter, we expect that revenue will be in the range of $82 million to $85 million. This range represents an increase of 6% to 9% over the revenue reported tonight for the first quarter. We expect little increase over the second quarter of 2011 because growth in factory automation and surface inspection is expected to be offset by lower revenue from the semiconductor, electronics and solar industries. Operating expenses are expected to increase by up to 3% on a sequential basis. And the effective tax rate is expected to remain at 21%.
Now let's open up the conference call for your questions. Operator, we are ready to take questions.
