2 -OMMN - Quality and Reliability Since many years we are active in the branch of conveyor- and hoisting technique as a supplier of solutions around control- and safety technology. The requirements on our products differ widely - from heavy industry applications on a building crane up to accurate positioning of machinery and highly sensitive devices. Together with our clients it is our aim to improve the safety of industrial machinery with our products. ecause of a flexible company organisation and decades of experience in this branch, we can turn a complex task into a customized solution within a short time. We work in a close cooperation to all partners of the supply chain - customer and supplier. ecause of this fact, we guarantee the quality of our products, even in difficult environments. Our aim is the highest quality and reliability of our products. ross Limit Switch for ranes The conveyor- and hoisting technique has to deal with huge requirements of both - operator and machinery. Operator and manufacturer of cranes put a enormous focus on permanent safety and reliability of machinery under all environmental conditions. The safe limiting of the end-positions of crane and trolley travel of overhead-cranes are realized by our cross limit switches. eside the basic stop-function of crane movement for each direction by using 2 contacts, we are also able to realize a slow down and stop-function by using 4 contacts. In addition special switching configurations allow an exclusion of defined areas out of the travel range of the cranes. ross limit switches of series lpha and Lambda are especially made for the heavy industry usage. ll used materials guarantee robustness, a good dimensional stability and max. resistance against oil, gas and extreme variations in temperature. The technological progress in crane development implicates higher requirements for cross limit switches. oth cross limit switches have been designed for high-speed cranes and can be used with max. 3m/s activation speed. The housings of the cross limit switches are made of extremely resistant zinc-diecast material, which are also resistant against high loads. oth series of cross limit switches are equipped with 3 possible cable-entries in size of M20x1,5. This allows a flexible cable-connection for the operator. dditionally we offer a pre-wiring. The operator can choose between: -elivery of pre-wired contacts with connector installed in the housing - elivery of pre-wired contacts with cable in desired length Realizing customized solutions in the shortest time, is a challenge we daily face. eside all standard cross limit switches we pictured in our catalog, we are able to offer a wide range of special solutions according to your requirements. We look forward to receive your inquiry. 2

3 ross Limit Switch Lambda Robust zinc die-cast enclosure Small, compact housing for minimum space requirements 2 or 4 contacts (1NO+1N each) Several switching configurations 3 possible cable entries ctivation speed: max. 3m/s Protection degree IP 65 ross limit switches of series Lambda stand for robustness and compactness. The compact housing is made of extremely resistant zinc-diecast material and offers space for up to 4 potential-free switching contacts. ross limit switches of series Lambda are available with different switching configurations. eside the basic stop-function of crane movement for each direction by using 2 contacts, we are also able to realize a slow-down and stop-function by using 4 contacts. Furthermore it is possible to create customized switching configurations according to your requirements. ll materials are resistant against oil, gas and extreme variations in temperature. The rubber sealing allows a optimum protection against dust and liquids, which is proved by protection degree IP 65. The small housing is perfect for a space-saving application. Product Specifications Space-saving small housing out of robust zinc die-cast material enclosure for up to 4 switching contacts Flexible cable-entry through 3 cable-entries M20x1,5 with screw thread Optionally pre-wiring of switching contacts and supply with cable in desired length. Optionally pre-wiring of switching contacts inside the housing and supply incl. connector for a easy replacement in case of maintenance. 3
