The SE120 has been designed to meet the needs for industrial applications where robustness and high performance are required. It features 64 pre-configured sounds each with 8 volume levels and a power range up to 120dB. Thanks to internal memory integrated on the PRO version, it is also possible to use customised messages on the 4 available channels, allowing the sounder to be fully configured to the individual needs.

The SE120 can withstand the toughest working conditions with a protection rating of IP66 / IP69K and impact resistance rating of IK08 ideally suited to the factory and industrial settings. The SE120 has been designed to operate in extreme temperatures with an operating range from -40˚C up to +60˚C.  The SE120 is available in Red or Grey and approvals include CE and UKCA.
