Rima System, Huntington Beach, CA, is a world leader in material handling and stacking equipment for post press and post bindery applications. They were using a sensor from one company and an interlock from another company on their automatic counting, binding and stacking equipment. To improve efficiency, Rima tested several sensors for performance in counting periodicals. The W.1000 photoelectric sensor by SICK offered superior sensing performance, particularly when sensing black ink, resulting in more accurate periodical counts. Once implemented, the accuracy of the W.1000 resulted in significant cost savings. Additionally, the "push to teach" teach-in function simplified setup and reduced programming time, making conversion to the W.1000 very easy.

The W.1000 series is the most technologically advanced, feature-rich, low-cost sensor available today. It has fixed background suppression that provides superior performance to focused sensors because the W.1000 utilizes the OES2 ASIC, our best-selling, cost-efficient chip. The OneTouch TM teach-in is simple and easy to set up. One press of the teach-in button and the sensor automatically sets itself up for your application. It has an integrated front snout for maximum strength and unchallenged durability. The clear status indicator is visible from four sides for highly visible status identification. The industry common mounting configuration allows easy adaptability to existing applications.

After the successful testing and implementation of the W.1000, Rima reviewed other products from SICK and elected to switch from their current supplier to the SICK i12 safety interlock switch. The compact size of the interlock and the match in form, fit and function allowed SICK to offer a "single-source" solution for the customer, providing streamlined purchasing advantages for Rima.

SICK's i12 interlocks have a small, compact body and are switched by means of a mechanical coded actuator. The durable housing is made of fiberglass reinforced thermoplastic with a protection class of IP 67. The i12 is a standard duty, M16 conduit entry, 1NC interlocking device. It has five actuating directions and standard or angle versions are available.
