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 the latest LED technology to ensure a long lifetime and offer distinct visibility in sunlit areas.

The functions of the A7 signalling columns are blinking or steady light and can be achieved by control from all types of PLC. An automatic electrical connection using a bayonet lock system with tension spring technology between the modules makes the signal column easy to use.

The A7 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 multi-sound buzzer modules, there is the option of eight different sounds, adjustable by dip switch, and a potentiometer for adjustment of volume.

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