Machine Vision: Diffuse Light Panels Growing in Popularity

Smart Vision Lights DLP Series illuminators are innovative and highly versatile lights. Think of a powerful backlight with a hole in the center. The result is homogeneous illumination similar to dome lighting.  These products emulate dome lighting by allowing light to come from multiple directions while giving the freedom to mount the light at a distance when domes must be mounted directly on top of the object.  

DLP lights can also be used to fill an area with soft diffuse light. This type of illumination reduces shadowing, reflection, and eliminates hot spots that point source spot lights can produce. The built-in LED driver makes connect-ability a snap featuring NPN/PNP strobe trigger input and remote analog intensity control through a 1-10V signal. DLP lights can run in continuous on or be pulsed. Available in multiple colors/wavelengths.

TURCK QR24 Rotary Contactless Position Detection

The QR24 provides contactless position detection and wear-free performance in a variety of industrial applications ranging from solar energy plants and harvesters to crane vehicles and AGVs.

Rotary feedback is critical in nearly every installation, and most rely on their mechanical bearings to provide proper tolerance and position of the internal system. After time, this results in mechanical wear, vibrations, potential leaks and requires spring elements. The QR24 provides superior performance without the need for contact or bearings, allowing it to successfully
execute the same functions as an encoder or potentiometer while eliminating wear and extending sensor longevity.

The Turck QR24 is part of the company’s industry-recognized Q-track family of sensors, which utilize resistance inductive capacitance (RLC) measuring technology. Unlike potentiometric or magnetic technologies, the sensors incorporate precisely manufactured printed emitter and receiver coil systems. The emitter coils are activated with a high frequency AC field and produce an inductive RLC circuit with the positioning element. The element is inductively coupled with the receiver coils, which are arranged so different voltages are induced in the coils, depending on the position of the actuator. The voltages serve as a measure for the sensor signal.

The QR24’s multi-coil system provides high resolution, while ensuring 16-bit noiseless operation. The sensor also features a double resonator system, providing increased distance capability and high-end signal processing with multi-core microprocessor for enhanced speed.
Along with advanced design features, the QR24 sensor features a fully potted and sealed IP69K/IP67-rated housing to protect against moisture and dust in demanding environments. It also offers flexible parameterization via IO Link or easyteach, allowing the sensor to easily adapt to specific application requirements.

Tolomatic's ERD Stainless Steel Electric Cylinder IP69K

Tolomatic has just released two new sizes of ERD electric cylinders that are hygienically designed, IP69K rated with an USDA Accepted Equipment Certification for meat (livestock), poultry, and dairy food processing applications.

The new hygienic stainless steel design of ERD electric cylinders offer:

  • Thrust capacities to 4500 lbf [20,017 N]
  • Increased strokes to 39.4 inches [1000 mm]
  • Increased speed capacities to 57.5 inches [1460.5 mm]
  • Choice of ball, or roller screws 
  • Lowest cost stainless steel actuator– with IP69K as standard equipment available out of the catalog with fast delivery 
With the expanded force range the ERD can handle the most demanding jobs such as pressing, cutting, chopping and can replace most pneumatic and hydraulic cylinders with excellent efficiency and operating flexibility.
