QST50BT-Ex LED Tower Light with Buzzer and Terminal Block

QST50BT-Ex LED Tower Light with Buzzer and Terminal Block

The QST50BT-Ex is a slim explosion-protected LED signal tower light designed for hazardous industrial environments where both visual and audible warning signals are required. The unit combines a 5-layer LED tower light, built-in buzzer and integrated terminal block in one compact housing.

A specially designed light diffusion tube improves long-distance visibility by concentrating and distributing the LED light. The long-lasting LED light source helps reduce maintenance requirements, while the aluminum housing provides excellent durability in demanding operating conditions.

The built-in buzzer provides sound output up to 90dB at 1 metre. The integrated terminal block allows convenient power wiring inside the housing. The QST50BT-Ex is available for DC 24V and AC 110-230V power supplies and provides IP66 protection.
