El Segundo, Calif. DDP has designed a LED-based stack light lamp to provide distinct visual indication of machine status from anywhere on a factory or office floor. The SL3 series stack light lamp provides 360 degrees of visibility, even in high ambient lighting conditions. Suitable for retrofits, the SL3 is designed as a drop-in replacement for a variety of incandescent bulb-based stack lights and signal towers.
Available in red, yellow, green, blue and white, the SL3 series features a small 15-mm diameter fresnel lens and offers a selection of base styles that allows for simple installation in a variety for 30-mm, 50-mm and 70-mm stack lights. The SL3 offers up to 100,000 hours of maintenance-free service. The LED stack light is available in T-4 ½ candelabra screw base, single- and double-contact bayonet base LED lamps. The LED stack light solutions are available in either standard or custom assemblies.
Offered in 12 Vac/dc, 24 Vac/dc and 120 Vac, the SL3 series stack light lamp features a rugged shock and vibration resistive design making the lamp suitable for harsh industrial applications. The series features a shunt resistor to reduce false indication from PLC leakage currents and other circuit protection devices to protect the lamp from voltage surges and ESD damage.
"The added circuit protection design prevents the lamp from over-voltage, reverse polarity, and electro-static discharge, extending the life of the lamp and reducing maintenance costs," said Tony Toniolo, president of DDP, in a statement.
Pricing typically starts at $10.50 in quantities of 1,000. Samples are available from DDP with a typical lead time of one week.
