LED pilot lamps are colour coded for speedy installation
25 April 2015
Available from Switchtec, the SCL range of pilot lamps is available in 16 and 22mm diameters for panel installation. the LED lamps have coloured terminals on the underside that are ‘coded’ to match the colour of the LED lamp on the ‘outside’.
The lamps are available for 12 and 24Vdc and 110 and 240Vac use and come in three versions: ‘standard’ PL16 and PL22; PL16-AI and PL22-AI that incorporate anti-interference technology to prevent the false illumination found in standard LED pilot lamps; PL22-LT lamp test version.
Differing from the standard PL22 LED pilot lamps, the PL22-LT incorporates a third connection terminal that is used to test the LEDs in situ without having to energise the whole panel.
All of the lamp versions are manufactured from flame-retardant ABS material and are available in the high visibility ‘pure’ colours of red, yellow, blue, green, and white. They consume much less power than incandescent types and have a life of 30,000 hours.
Installed in a panel, they achieve an ingress protection ration of IP65.
