WERMA

WERMA is a German manufacturer of industrial signaling devices, with a product line that includes tower lights, flashing light modules, sounder modules, and mounting accessories. The company was founded in 1950 and is headquartered in Rietheim-Weilheim, Germany. WERMA's product families are designed for machine status indication, process monitoring, and alarm signaling in industrial environments. The KombiSIGN series, including the 40, 71, and 72 variants, forms the core of their modular tower light systems, allowing users to configure multi-tier assemblies with colored light tiers (green, red, yellow, white) and optional sounder tiers. These devices are typically rated for 24V AC/DC operation and are built with IP65-rated enclosures for dust and water ingress protection, suitable for factory floor and outdoor installations. WERMA also offers flashing/strobe modules, siren sounders, and wall-mount brackets that facilitate flexible mounting on machinery or control panels. 3G Electric supplies WERMA signal towers and components globally, supporting plant engineers and maintenance managers who require reliable visual and audible indicators for equipment status. The modular design of WERMA products enables easy field configuration and replacement of individual tiers, reducing downtime during maintenance. Specifications such as overall height (ranging from 59 mm for single modules to 299 mm for three-tier assemblies), operating voltage (24V AC/DC), and lens colors are standardized across the series, ensuring compatibility between components. WERMA's sounder modules offer intermittent or continuous siren tones, with sound pressure levels typically around 85 dB at 1 meter, providing clear audible alerts in noisy environments. The mounting brackets are constructed from black plastic with integrated cable glands, simplifying installation. For procurement specialists, WERMA's product numbering system (e.g., 96000001 for a bracket base) allows precise ordering of replacement parts or complete assemblies. 3G Electric's logistics support ensures that these components are available for global shipment, with technical documentation provided to assist with integration into existing control systems.

Common Applications

  • Machine tool status indication — WERMA KombiSIGN 71/72 tower light assemblies (e.g., SKU 452T34) used to show green for running, yellow for standby, red for fault.
  • Conveyor system alarm signaling — WERMA flashing light modules (e.g., SKU 452R75) mounted on conveyor frames to indicate jams or emergency stops.
  • Process control panel monitoring — WERMA 4-tier tower lights (e.g., SKU 452T92) with sounder tier for audible and visual alerts in chemical processing plants.
  • Automotive assembly line quality control — WERMA 3-tier assemblies (e.g., SKU 452T30) at inspection stations to signal pass/fail/rework status.
  • Outdoor equipment status — WERMA IP65-rated tower lights on water treatment pumps or HVAC units for remote visual monitoring.
  • Warehouse racking safety — WERMA wall-mount brackets (e.g., SKU 452T63) supporting tower lights at aisle ends to indicate forklift traffic or zone status.

Frequently asked questions

Common questions about WERMA from 3G Electric.

What is the operating voltage range for WERMA KombiSIGN tower light assemblies?

WERMA KombiSIGN tower light assemblies, such as the 3-tier models (SKU 452T34, 452T30, 452R58) and 4-tier model (SKU 452T92), are designed to operate at 24V AC/DC. This dual-voltage capability allows them to be used in both AC and DC control circuits common in industrial automation. The flashing light modules (e.g., SKU 452R75) and sounder modules (e.g., SKU 452R96) also operate at 24V DC. Always verify the specific voltage rating on the product label before installation.

Are WERMA tower light modules interchangeable between the KombiSIGN 40 and 71/72 series?

WERMA tower light modules are series-specific. The KombiSIGN 40 series (e.g., flashing module SKU 452R75, sounder module SKU 452R96) uses a 40 mm diameter base, while the KombiSIGN 71/72 series uses a larger 70 mm diameter base. Modules from one series are not mechanically or electrically compatible with the other. Wall-mount brackets (e.g., SKU 452T75, 452T63) are also designed specifically for the 71/72 series. Always select components from the same series to ensure proper fit and function.

What IP rating do WERMA tower light assemblies typically have?

WERMA KombiSIGN tower light assemblies and modules are generally rated IP65, meaning they are dust-tight and protected against water jets from any direction. This makes them suitable for use in wet or dusty industrial environments, such as food processing plants, automotive assembly lines, or outdoor installations. The IP65 rating applies to the assembled unit when properly installed with the included gaskets and cable glands. Check the specific product datasheet for exact ratings, as some modules may vary.

Can I add a sounder tier to an existing WERMA tower light assembly?

Yes, WERMA tower light assemblies are modular, allowing you to add or replace tiers. For example, the 4-tier assembly (SKU 452T92) includes a sounder tier, while 3-tier assemblies (e.g., SKU 452T34) do not. You can purchase a separate sounder module, such as the siren sounder (SKU 452R96) for the KombiSIGN 40 series, and integrate it into the stack. Ensure the sounder module matches the series (40 or 71/72) and voltage (24V) of your existing assembly. The sounder tier typically mounts between light tiers or at the top of the stack.

What is the sound output level of WERMA siren sounder modules?

WERMA siren sounder modules, such as the model for KombiSIGN 40 (SKU 452R96), produce an intermittent siren tone with a sound pressure level typically around 85 dB at 1 meter. This level is sufficient for audible alerts in moderate-noise industrial environments. The sound operating mode is intermittent (pulsing) to distinguish it from continuous alarms. For higher noise areas, consider using multiple sounders or a louder model. Always refer to the product datasheet for exact decibel ratings and frequency characteristics.

How do I mount a WERMA tower light assembly on a wall or machine?

WERMA offers wall-mount brackets specifically for the KombiSIGN 71/72 series, such as the bracket base (SKU 452T75) and wall mount bracket (SKU 452T63). These brackets attach to a flat surface using screws (not included) and provide a mounting point for the tower light stack. The bracket includes a cable gland for routing wiring. For the KombiSIGN 40 series, a separate mounting base is typically used. Ensure the bracket is compatible with your tower light series and that the mounting surface can support the weight of the assembly.
