Reflective Laser Sensors

IX series - Image-Based Laser Sensor

IX Series image-based laser sensors can measure height anywhere within the area. Camera-based image recognition allows the laser to detect the height of the target point even when workpieces are not perfectly aligned on the production line. The height of where the laser hits the target will vary if the target is tilted or if the target itself is different, but the IX Series can identify the difference in height against the reference. For example, in a parts assembly line, a single IX Series unit can not only check for the presence of parts, but also perform seating checks and other height-based inspections. Thanks to its ability to detect height differences, the IX Series is also free from false detections and errors in the presence of glare from glossy surfaces of metal parts or when the detection target point has the same color as the background, offering stable automatic inline differentiation.

IL series - CMOS Multi-Function Analog Laser Sensor

IL Series CMOS multi-function analog laser sensors are reflective laser displacement sensors that provide the best-in-class detection ability and stability at reasonable cost. Stable detection is possible without tuning for workpiece types or their surface conditions, so the IL Series can be added to production lines to help make setup, changeover, and product changes easier. With a wide-ranging lineup of sensor heads, including high-accuracy models and long-range (up to 3.5 m 11.5') models, these laser sensors can be applied to diverse applications thanks to their broad dynamic range and environmental resistance. 1 μm repeatability allows for use in high-tolerance detection setups that previous sensors could not stably provide.

LVDT / Contact Sensors

GT2 series - High-Accuracy Digital Contact Sensor

To increase longevity—a common challenge with contact-type displacement sensors—the structure of the main body has been fundamentally re-examined for the High-Accuracy Digital Contact Sensor GT2 Series. The structure, including the relay connector and cable, ensure stable measurement even in environments with splashing water or oil. In addition, the reduced weight of the spindle means minimal friction wear and significantly improved durability. A wide variety of sensor heads are available, including pencil type, air push-type, and low-stress type. The GT2 Series offers two types of detection methods: LVDT (linear variable differential transformer) and Scale Shot System II. This allows use across various applications. The varied lineup of communication units enables communication with PCs and PLCs from various manufacturers.

GT series - General Purpose Digital Contact Sensor

The General Purpose Digital Contact Sensor GT Series is a contact type sensor designed for ease of use and reliability. It can be installed easily in existing facilities, allowing for quick startup of the production line after installation. It also has an easy-to-see display and a self-diagnostic function for checking for conditions such as a trapped spindle or cable disconnection. There are two types of mounting for the amplifier: DIN type for rail mounting and panel type for panel mounting. Selecting the correct type for the installation environment is effective for simplified wiring. Various functions are included to complete the setting with minimum steps. The sensor can be used immediately after installation. The easy-to-see indicators clearly show judgment results and errors during measurement.

Thrubeam Laser Sensors

IG series - Multi-Purpose CCD Laser Micrometer

IG Series multi-purpose CCD laser micrometers provide high-precision differentiation that is unaffected by how much light the target transmits. This series uses a line-charge coupled device (L-CCD) as its light receiving element. Instead of using received light intensity, it captures the edge of transmitted laser light, so it can perform high-accuracy, stable differentiation with 5 μm repeatability and ±0.1% linearity. This makes the IG Series capable of supporting various applications, including edge detection and positioning of clear glass, precise recognition of workpiece OD, feedback control while detecting a sheet edge, and roll gap measurement. The positioning monitor on the main unit facilitates optical-axis alignment when starting up a line and during changeovers.

IB series - Thrubeam Type Laser Detection Sensor

IB Series thrubeam type laser detection sensors cater to a diverse range of applications by differentiating received light intensity with high accuracy. This series uses a photodiode (PD) for its light receiving element. By accurately detecting the changes in received light intensity, it can support various applications without being affected by the target. For example, the IB Series can be used for applications that are impossible with photoelectric sensors, such as detection of liquid crystal glass and liquid turbidity, differentiation of film types, tilt detection of chips, and incorrect seating of caps, all at low cost. The compact sensor head is equipped with an alignment LED, so optical-axis alignment is easy.

Ultrasonic Sensors

FW series - High Power Digital Ultrasonic Sensors

FW Series high power digital ultrasonic sensors are super multi-reflective, non-contact level switches that can perform stable detection of any target. They are not affected by the color, pattern, luster, or transparency of surfaces, so they can be used for any target, including liquid levels, metal, and glass. The IP67-compliant sensor heads have excellent environmental resistance and emit powerful ultrasonic waves that penetrate some dust and dirt to detect workpieces. The newly included A.W.S. (active wave stabilizer) algorithm eliminates the influence of target vibration or ambient light. The N.O.D. (nearest object detection) function detects only the nearest target without being affected by the luster or shapes in the background. This makes it possible to perform stable detection of any target in any installation environment.
