Germany SICK Introduces Position Sensor OLM Series Based on Bar Code Reading Principle

Following the maturity of the family of laser ranging sensors, SICK recently introduced the linear distance sensor OLM series. By scanning the bar code information on the fixed track, the linear sensor acquires the current position information to quickly and accurately position different trajectories of a straight line or a curved line. This feature of the OLM series offers more options for the application of the logistics industry.

Typical applications such as overhead electric conveyors, track shuttles, turntables and toroidal turntables, lift systems and robotic arms, etc., have become increasingly important for reducing blind spots such as precise positioning at corners. The OLM series is non-linear. The positioning provides the best solution. By scanning the 3cm adjacent spaced bar code blocks on the track, the sensor obtains current position information up to 0.1mm resolution and provides data interfaces such as Profibus (OLM200), RS422, RS485, SSI, and CANopen (OLM100). Information is input to the upper control system.

Superior performance provides unlimited possibilities for applications

The optical principle of the linear sensor OLM100 is designed for high-performance measurement, and at the same time integrates a rugged shell, using a more stable and reliable LED light source principle, while discarding the traditional rotating mirror-type light source. The light source of the sensor provides the strongest brightness, and it is very easy to align the bar code during installation and debugging. At the same time, it also greatly enhances the ability of reading and resisting ambient light interference. At the same time, the built-in backplane and four mounting screw holes and T-slots provide convenience and cost savings for installation on different occasions. The OLM100 offers a 100 mm +/- 20 mm range for mounting orientation, providing excellent flexibility for reliable positioning in horizontal direction.

Drive reading applications forward

SICK's bar code reading provides promising solutions for a variety of applications. It can flexibly and reliably respond to the effects of thermal expansion and contraction brought about by changes in temperature from -30°C to +60°C in various industrial environments. Pulling of the small-range bar code can be adjusted by the degree of tightness of the sticking, and the pull-up or interruption of the wide-range bar code can be adjusted and matched by a single special separate bar code. If the local bar code is damaged or dirty, SICK's website allows the customer to directly download the corresponding bar code segment to print and replace (.com/OLM).

The OLM100 provides an ideal solution for positioning linear and curved traces. Whether it is a flexible use of methods, reliable industrial performance, and convenient and low-cost installation and maintenance and other features, have provided customers with a trusted quality.
