Leuze A7 signalling columns

The A7 signalling columns from Leuze are modular and offer flexible configuration in a 70 mm-diameter housing. The clear lens modules are designed with LED technology to ensure a long lifetime, offering distinct visibility in sunlit areas. The functions for the signalling columns are blinking or steady light and can be achieved over all types of PLCs. An automatic electrical connection using a bayonet lock system with tension spring technology between the modules makes the signal column easy to use.

The signalling columns are available with or without a buzzer. For single-sound buzzer modules (up to 105 dB), options are steady sound, pulsing sound or potentiometer for adjustment of volume. For multiple-sound buzzer modules, options include eight different sounds, sounds adjustable by dip switch and a potentiometer for volume adjustment.

The pins of each lens are connected to the colour, not to the position. This allows the operator to easily change the order of the modules. Three different pole lengths (100, 250 and 400 mm) are available. A pre-assembled tower light with a 100 mm base in red, orange or green is also available.
