Key Features
High-volume 98 dB Output in a Slim, Compact 54 mm-Deep Design
Delivers high-volume sound output of up to 98 dB (Typ.) *1 , while maintaining a compact design with a depth of only 54.0 mm, approximately 40% slimmer than the previous model *2 . It helps save space in control panels and equipment, and enables easy installation even where space is limited.
- The sound pressure level may vary depending on the playback content and the operating environment.
- Compared with our previous model.
High Dust and Water Resistance for Outdoor Use (IP65)
Complies with the IP65 degree of protection. Its rugged design allows reliable use in factories exposed to water and dust, as well as in outdoor environments, making it suitable for a wide range of installation environments.
This protection rating applies to the product itself. Waterproof performance when installed in a panel depends on the mounting conditions and quality of installation, such as sealing.
Front-Access Structure Reduces Installation and Adjustment Work
The front-locking structure allows panel mounting, removal and volume adjustment from the front using only screw operation. There is no need to work from the back of the panel, significantly reducing installation and maintenance time.
32 Built-In Sounds Controlled by Bit Input
Includes a total of 32 built-in sounds, including alarm sounds, melodies and chimes. Sounds can be selected from 8 sound groups using DIP switches, and up to 4 sounds can be assigned by bit input. One unit supports a wide range of notification needs. All included sound sources are copyright-free.
The sound replacement function using an SD card, which was available on previous models, is not included with this product.
4.5G Vibration Resistance for High-Vibration Installation Environments
The DC 12–24 V model (M1) provides 4.5G vibration resistance, allowing installation around equipment subject to high vibration.
NPN and PNP Models Available
Both NPN and PNP input specifications are available as standard model options. Select the model that matches the specifications of the connected equipment.
AC 100–240 V models support NPN input only. DC 12–24 V models are available in both NPN and PNP versions.
