Auer Signal - Modular signal towers with LED

Would you like to see or hear the status of a specific machine from a distance? Then use a modular signal tower. The ECOmodul from Auer Signal has many different options and mounting options, so that you can assemble exactly the signal tower as you wish it.


The ECOmodul from Auer Signal uses a very bright LED technology, making the signal even more visible. Connection is simple, namely via spring pressure or push-in technology. Developed and built for many years of trouble-free use in the industry. Read more about signal towers.

The ECOmodul signal towers are available with different diameters: 40 mm, 60 mm and 70 mm. 


diameter: 40 mm diameter: 60 mm diameter: 70 mm

The highest standard in the international signaling market

Series T (ø 75 mm) and U (ø 60 mm) signal lights are available as surface-mounted and panel mount version in several variants. Also optical-acoustic and acoustic models of the T model are available.

Auer Signal for extreme applications

With this expansion of the program Auer has the perfect alerts for extreme and demanding applications. A temperature range of from -30 °C to + 60 °C, IP66 and a seal made of an impact resistance to IK10 are examples of highly robust design. Read more about signal lights.

Modul Perfect 70 - PC7 - Modular signal tower - Auer Signal

The highest signal tower - PC7 - Auer Signal

The PC7 is the highest and most versatile signal tower of Auer Signal with seven positions. The Auer Signal PC7 is 13 times brighter than the previous model. The upper module is even brighter than the standard light modules and has an extensive, hemispherical signal effect.


7 colors can be switched externally in the LED multi-color module: red, yellow, green, blue, transparent, magenta and turqoise. Thanks to binary switching, 4 additional modules can be used in addition to a multi-color module. Read more about the Modul Perfect PC7 from Auer Signal.

Acoustic signaling - Auer signal

Machines must be provided with alarms from a distance, so that the condition of the machine is visible. Visual signal facilities must be clearly visible to the user and sound signals must be clearly audible, taking into account environmental noise.

Alarm, buzzers, sirens

Auer Signal offers a wide range of alarms, buzzers and sirens to make the status of the machine audible from a distance. The acoustic signaling products also offer the solution for fire and fault reports.

Telephones - Auer Signal


The weatherproof and explosion-proof phones from Auer Signal are resistant to harsh environmental conditions. The phones can withstand temperatures of -40 ° C and +60 ° C. The telephones can be used in ATEX zones 1, 2, 21 and 22.

Wet, potentially explosive environments

With a degree of sealing of IP67, the telephones can be used in wet and potentially explosive atmospheres. Within the range, a difference is made between explosion-proof and water-resistant telephones.
