Slotted Optical Switches Utilized in Credit Card Printers


TT Electronics’ OPB841W55Z was successfully used in a bank credit card printer. Our customer was looking for a side mounted sensor to detect the presence of blank plastic credit card as it passes through the machine to be embossed, coded and to magnetize the black strip. Our OPB841W55Z with a customised cable harness helped solve their challenge. The customer chose to work with us because our brand Optek, supplied a cost-sensitive, side mount transmissive sensor with a customised cable harness, making us the preferred supplier with 7 transmissive switches in this printer. This simplified the customer’s supply chain and reduced their cost.
