Laser sensors claim distance accuracy
standards
A new range of laser sensors is billed as setting a new standard for high performance distance measurement.
Setting a new standard for high performance distance measurement, Sick introduces the new DT/DS 500 laser sensors Able to measure distances up to 30m with an accuracy of +/-3mm without a reflector, the DT/DS 500 detects and measures the distance of almost any object precisely and reliably

Vision sensor promises photoelectric ease
The Inspector's rugged IP67-protected metal housing ensures it can withstand harsh industrial and production line environments, for quality assurance inspection in any location or orientation.
Incremental encoders provide smooth running
Bearings are separated as widely as possible within the encoder body, to achieve smooth and vibration-free running.
Easy to set up via the built-in display and membrane keypad, and protected by a robust metal housing, the DS/DT 500 can handle the most demanding applications in the materials handling, industrial and logistics industries.
With a Class 2, eye-safe laser diode producing a visible point of red light, it is easy to align the laser on to the target.
Even without a reflector the DT/DS 500 is able to operate over distances of up to 30m with white target surfaces and an impressive 18m with black targets.

Sick's 120-page direct part marking book guides the engineer through the choice of technologies for permanent identification of components and finished products.
By measuring the time of flight of the light beam to and from the target, the DT/DS 500 is able to calculate the distance of the detected object with an accuracy of +/-3mm and a repeatabilty of 1mm every 250ms.
The integral display shows the distance measurement from the target in millimetres to enable parameters to be set during the simple "teach-in" configuration process.
The DT/DS 500 is rated IP65 and can operate in temperatures from -10 to +50C as standard.
For outdoor applications a weather protection hood is available, while an integrated heating element can also be fitted to allow operation in cold stores at temperatures as low as -40C.
The DT 500 is a versatile universal distance measurement sensor offering users a choice of data output between an RS422 serial interface and 0-20 or 4-20mA analogue output.
The user can quickly configure the sensor's outputs to enable measurement of distances between 0.2 and 30 m, and the DT 500 can be used in a variety of demanding applications including loop control in steel and tyre manufacture, level control in silos, stack height measurement, parts positioning and coil diameter measurement.
The DS 500 is a precise object detection sensor with two switched outputs that can be set up by the user to operate at pre-determined distances between 0.2 and 30m.
The high resolution of the DS 500 ensures reliable detection of the target object against bright background surfaces, making it ideal for critical or difficult applications such as anti-collision control for high speed gantries or cranes, detection of small parts over large scanning distances and detection of low reflective objects such as tyres and shipping containers.
Sick offers a wide range of laser scanning sensors to suit a variety of distance measurement and object detection applications, and with the launch of the DT/DS 500 it sets a new standard for performance, reliability and ease of use.
