With a small bearing on the rotation axis, the light shows high durability and stable operation. Its vacuum- deposited reflector rotates to radiate an intensive flashing light. This light is excellent in weather proofness and light penetration because of the use of heat-resistant AS resin globe. The light with a built-in buzzer generates intermittent sound (volume : 90dB) and operates with warning light at the same time. It is suitable for signal transmission for robot production lines, small tooling machines and automatic conveyor lines.
