The Werma 635.700.75 is a KombiSIGN 40 Series Electronic Sounder buzzer engineered for robust industrial signalling tasks. Fitted with a high integrity polycarbonate housing and IP66/IP69K protection ratings, this buzzer withstands dust, high-pressure, and high-temperature water jets, making it well-suited for demanding process environments and safety-critical installations.
Operating at a supply voltage of 24V AC/DC, the buzzer offers flexible wiring and integration, accommodating common voltage standards in control panel systems. At 1 metre, the sound pressure reaches 85 dB, ensuring clear audible alerts across noisy workshops, factory floors, and construction sites. Its 2-tone capability allows operators to deploy distinct audio signals for different warning states or operational phases, with the option to select continuous or pulse mode as per application requirements.
The surface mount format enables simple and rapid installation on control panels, equipment housings, or automation enclosures. With a compact diameter of just 40 mm, the buzzer delivers high performance without taking excessive panel space. Its housing material - polycarbonate - improves durability and resistance to impacts, chemicals, and outdoor conditions. The grey colour is neutral and professionally suited for industrial settings.
Reliability is a core aspect, with the buzzer offering an acoustic rated service life of at least 5000 hours, supporting extended use in safety and signalling systems. The maximum operating temperature is 60°C, ensuring functionality in high ambient temperature zones. The electrical consumption is minimal, with a nominal current rating of 80 mA, containing running costs for continuous operation.
Applications for the Werma KombiSIGN 40 Series buzzer include automation signalling, machine safety alerts, process notification, emergency evacuations, and maintenance status indication. Common sectors include construction sites, automotive workshops, factory automation, and industrial production lines.
For controlling diverse alert scenarios the buzzer's configurable tone modes and robust environmental protection deliver reliable signalling, meeting both CE and UKCA regulatory standards. Backed by Werma's professional range, the device guarantees consistency and performance in advanced automation systems.
