Polycarbonate
This material offers UL94 V-0 flame retardancy* and a high impact strength. This material has a melt point of 290-340°C and is suitable for use in
the majority of automatic soldering processes.

LEDs
LED Polarity
Anode identification is shown in the dimensional diagram. The long lead of a non-cropped unit can also be used to help identify the anode. For
the 2 pin Bi-colour units the standard colour configuration is red anode to the ‘+’ sign.
Reverse Polarity
This is offered on all PCB units, with the exception of the 125 series, if requested to help overcome the problem of systems with reverse polarity
reverse colour configuration.

o acheive the second colour for a 2 pin Bi-colour unit the supply must be reversed, standard colour configuration for these units is red anode to

Electro-static Discharge (ESD)
Build up of electrostatic discharge occurs in many situations involving people moving and handling products. The range of possible situations is
very diverse but voltage levels as high as several thousand volts can and do arise in many individual situations. When an operator charged up to
these levels handles a ‘static sensitive device’, there is a very probable likelihood that the device will be irreversibly damaged. It is essential that
precautions are taken at all stages during manufacture and assembly of these products. Although LEDs were never considered to be static
sensitive devices, changes in manufacturing technology and materials used to produce higher intensityproducts over a large range of the
and despatch. We recommend all users of LED based products follow the guidelines of BS 100015.
