Belt systems in factories producing chemical materials are more practical and miniature than heavy industrial factories. In the conveyor band systems used to increase the work speed during the production phase, limit switches are needed for emergency stop and to control the band in desired areas. KBT NSR 55 and NSR75 series products which are produced exactly according to the needs are preferred. Position limit switches are preferred in order to control where the products are on these band structures that work together with the machine park. Emergency stop switch is used for machine safety. Since TPR 55 series products are BMC Composite material, they are not affected by unpackaged chemical products.
