153 Series PCB Indicators from Aerospace and Defence Products are 3mm in size. These right angle surface mounting PCB indicators feature a standard intensity diffused LED element in a range of colours and voltages. These indicators are moulded with fixing spigots for ease of assembly and secure anchoring during flow soldering. The precision black moulded housing manufactured to UL 94 V-0 flammability rating material emphasises the mechanical stability and on/off contrast ratio of the component. Their benefits include savings on board space and production assembly time.
