This family of LED lens caps, from Keystone, are in round configurations. They are designed for use with standard 3mm (T-1) and 5mm (T-1 3/4) through-hole LEDs with both diffused and non-diffused lenses. Installation is made easy by snap-in mounting through the panel. The LEDs can then be pushed in by hand, placing them into the cap using light pressure. It is then held securely in place due to the lens cap design.
The round lens caps are ideal for protecting the LED against any physical damage, thus potentially improving the life time of the LED in harsher environments. The cap also guards the LED from any electrostatic discharge (ESD) of up to 16KV.
Available in a variety of colour options, including clear, the round LED lens caps are made from a polycarbonate material. The coloured caps are ideal for providing high contrast and visibility.
