The PJ-H30 series with its slim, compact design significantly decreases the distance between the focusing wheel and projection screen, compared with conventional models. In addition, measurement efficiency is improved because the 2D data processor (QM-Data200)is connected to the main unit with its large LCD screen positioned close to eye level. The compact main body unit is common to every model in the series. The turret in the PJ-H30 series uses a bearing in the rotary and positioning units to change the projection lens with a gentle and quick sliding action. The turret unit employs a bayonet mount that makes it easy to attach or detach a lines. The PJ-H30 series uses continuously variable brightness control so that a workpiece can be illuminated at the appropriate level according to its surface texture and color.

This illumination system generates illumination from low to high intensity, and can be effective in lengthening the halogen bulb life. Also, the illumination does not start suddenly but increases gradually to the set level. A quick release mechanism inside each X and Y wheel can switch the stage between Fine Feed and Unlocked. In the unlocked position the stage is completely free moving so it can be shifted very rapidly by hand to the next measuring point. This is very convenient and efficient when long-distance movements are needed, or for a quick return to the reference point. Thanks to the twist roller method used in the mechanism the feed is smooth with minimum shock during switch over. A pro .le projector requires not only appropriate optical performance but also a high level of accuracy. The PJ-H30 series projectors, designed for two-dimensional measurement with high accuracy in addition to contour observation and comparative inspection. This PJ-H30 series has achieved long-stroke measurement and high-accuracy measurement simultaneously, and thus are suitable for practically every industry. Highly Dust Resistant for Use in Any Location Profile projectors are used in widely varying locations, from machine shop to inspection room, with all the associated variations in atmospheric cleanliness.

The PJ-H30 series has been designed for continuous use under these conditions by increasing the dust resistance of the contour illumination unit beneath the stage glass. Additionally, the protection glass is mounted on this illumination unit to avoid damage to the condenser lens and make cleaning much easier. Built-in Auto Edge Detection Function The model PJ-H30B/30D incorporates the Opto-eye sensor that outputs a signal upon automatic sensing of a low or high intensity at an edge (under the contour illumination).The sensor allows auto edge-detection measurement while performing chart comparison inspection on the projection screen. Additionally, because calibration can be set up according to each low or high intensity level on the projection screen, a high accuracy of edge detection has been achieved. Dual-mode Surface Illumination Unit Surface illumination is provided by a swiveling lighting unit that can direct light onto the side window in a projection lens for reflection vertically downwards through the lens itself ,or that can illuminate the surface directly. This illumination system is useful to increase the color reproducibility of a workpiece and perform three-dimensional observation. High-operability Focusing An easy-to-grip wheel shape and a convenient location are key factors for quick focusing on a workpiece placed on the stage. The manual focusing wheel in the PJ-H30 series is mounted at an angle so it can be operated from a natural pose without feeling uncomfortable even in a standing or sitting position. The motor-driven focusing spec model with a high-operability jog shuttle that moves smoothly is also available, allowing observation and measurement with minimum feeling of fatigue. Bulb Housings Designed for Ease of Replacement The bulb housings of the PJ-H30 series are designed to allow quick and safe bulb replacement, particularly for the contour illumination bulb which is mounted on a sliding tray to provide easy, external access. This ensures that contour inspection can be continued as soon as the bulb has cooled to a safe temperature after failure. Bulb replacement is very simple because the housing can be released just by loosening one screw. Current to the bulb is shut off while the housing is pulled out. Maximizing Bulb Life Halogen bulb life is greatly dependent on the characteristics of its power supply. Specifically, inrush current at switch-on with conventional AC supplies is a big overcome this effect, the PJ-H30 series uses a regulated switching power supply that delivers DC with a soft-start characteristic to help ensure the rated bulb life and light intensity is achieved. It also allows operation in shortening the rated life of a halogen bulb. country without the need for adjustment to local mains power.
