Information for the contacting unit of the COR-B20
- The contacting unit for the chip card is produced for 10 years in a large quantity. It is
sophisticated very solid and is also used for outdoor applications.
- All materials of the contacting unit are water resistant (i.e. synthetics, high-grade steel,
gold-plated contacts for contacting the chip and gold-plated contacts at the limit switch).
- There can only be problems with frozen contacts. If the card is put in more times the
ice on the contacts will detach. For preventing the contacts of freezing we recommend
to use a heating inside of the vending machine.
