Pilot Lights

Pilot lights are indicator elements mounted on a panel door or control box that show with colored light whether a circuit is energized, running or faulty. They are used to show phase presence in electrical panels, running, stopped and fault status in motor and pump controls, and process status in operator panels. This category includes models with 22 mm, 16 mm and 30 mm mounting diameters with LEDs, bulbs and Ba9S sockets, types with buzzers, and pilot lights with voltmeter and ammeter displays; EMAS, Schneider Electric, Siemens and Gwest products are listed. Choose the light according to the hole diameter in the panel, the voltage of the control circuit (for example 24 V AC/DC or 230 V AC), the color, the light source and the IP rating of the panel. On machine controls, colors carry meaning according to IEC 60204-1: red indicates a dangerous condition, yellow an abnormal one, green a normal one, blue a condition requiring operator intervention, and white general information. Since the cap, holder and LED block may be sold separately in modular series, check the product name to see whether the product is a complete light.

How to choose Pilot Lights

Pilot lights are indicator elements mounted on a panel door or control box that show with colored light whether a circuit is energized, running or faulty. They are used to show phase presence in electrical panels, running, stopped and fault status in motor and pump controls, and process status in operator panels.

  • Separate sensing, motion control, logic processing and operator interface requirements.
  • Select signal type, supply voltage, communication protocol and I/O count for the machine network.
  • Verify housing size, sensing distance and PNP/NPN output polarity against the PLC input card.
