NLA50 Series | Crystal Diamond Signal Tower

NLA50 crystal light cover signal tower

Features

The large illuminated area provides clear indication with low power consumption.

This signal tower uses multi-layer LEDs in red, yellow, green, blue, and white.

The signal color sequence can be customized.

The constant-current drive keeps brightness stable even when the input voltage changes and helps extend LED service life.

The independently developed protection circuit design protects against surges and unstable currents at the moment the power is turned on, or instantaneous power outages.

Applications

Semiconductor Equipment, Machine Tools, Automation Control Systems, Driveway Entrances and Exits, and Parking Lots.

NLA50 series

The crystal light cover signal tower uses a reflector and supports one to five light layers.

The larger reflective area provides brighter, more uniform 360-degree light emission.

Comparison with Other Signal Towers

NIKKI signal towers use a transparent light cover. When the light turns on, the entire light cover is illuminated, making the status easy to identify from a distance and helping reduce missed or mistaken signals.

Signal Tower Light Cover Options

Transparent and milky white signal tower lenses

Choose a transparent or milky white light cover to match the application environment.

A transparent light cover is recommended when long-distance visibility is important, such as inside factories, warehouses, or parking areas.

A milky white light cover is recommended for close-range environments such as checkout counters or offices, where softer light is easier on the eyes.

Transparent Light Cover: Factories, warehouses, and parking lots.

Milky White Light Cover: Cashier counters and offices.

Features

  1. Compact design saves installation space.
  2. Open-loop control is supported, allowing direct PLC control.
  3. The lighting position can be adjusted by tilting the body.
  4. The nylon housing provides heat resistance and oil resistance.
  5. LED modules can be changed freely, and light layers can be configured according to customer requirements.
  6. CE/FCC certified and tested for vibration resistance and insulation resistance.
  7. Diffused light cover options are available. The built-in reflective surface refracts light through the light cover so each layer emits evenly.
  8. The exclusive decagonal light cover and internal curved reflective surface improve visibility across the full light cover area.
  9. The resonant buzzer design increases volume up to 95 dB (measured at 1 m), making it suitable for noisy factories.
