MENTOR applies for patent for 7-segment display with infinitely variable height

Conventional 7-segment displays still compensate these height differences either via DIL sockets or sophisticated sandwich printed circuit boards. The 7-segment displays from MENTOR resolve this problem with variable heights between 4.5 mm and maximum 23.5 mm and can be produced to meet individual customer requirements using tool change inserts. These custom-made 7-segment displays can be tailored to suit diverse design requirements and thus offer a significant advantage in the assembly process compared to standard solutions.



Individuality through modular design

Conventional 7-segment displays have permanently integrated LEDs offering little scope for individual design. The new 7-segment display from MENTOR offers a choice of SMD LEDs to suit specific applications: in addition to a choice of colours, Duo and RGB LEDs can also be used on printed circuit boards including low-current SMD LEDs.

A further advantage: the modular design of this display allows individual component replacement in the event of a faulty LED – conventional segment displays must be replaced as complete units.



Technical design

The 7-segment display is produced in a two-component injection moulding process with an opaque multi-chamber body and light guides as the segment display in three standard digit sizes of 7.62 mm, 10.16 mm and 14.2 mm. The displays are attached to the printed circuit board via two fixing pins on the underside of the housing.



In addition to individually variable heights, MENTOR also offers 7-segment displays in two standard heights of 9.7 mm and 12.5 mm.
