October 1, 2013 - Patlite introduces LS7-9 Series Signal Light Towers which feature a smooth surface design that is IP69K rated to withstand high-pressure and high-temperature washdown operations. Additionally, with no exposed screws, shafts or other metals components, the LS7-9 is ideally suited for sanitary environment applications such as the food and beverage industry, as well as equally stringent, harsh industrial settings on machine tools and production equipment. The stackable design with optional M12 quick disconnect significantly simplifies installation and can reduce costs by eliminating the need for a separate relay box.
LS7-9 series signal towers feature a state-of-the-art inner lens design that emits a sharper and more efficient LED light than is available with other signal tower designs. Models are available in three or five light tier configurations with a wide range of user-selected colored LED light arrangements. A durable shock resistant polycarbonate lens ensures long life and reliable operation. An optional 2000 Hz to 3000 Hz buzzer emits a sound frequence that can "cut through" the sound from operating machinery that would normally drown out other buzzer sounds.
