The EMAS IF3N024MS30-1 gives you five status colours in a single low-profile 50mm dome (selected by which wire is switched, not by swapping lenses). It mounts through a 30mm hole and is rated IP67, so it suits tight clearances and washdown or exposed locations where a taller beacon or tower won't fit.
This is the NPN (sinking) version for 24V DC PLC outputs. For PNP (sourcing) outputs choose the IF3P024MS30-1 (PNP). For a 22mm-mount alternative with a buzzer, see the IF5P multicolour beacon.
- 5 colours from one 50mm dome
- 24V DC, NPN (sinking) switching, direct from PLC outputs
- Low profile for small clearances
- M30 mounting (30mm hole), IP67
- Heat-resistant clear polycarbonate, monoblock construction
- Supplied with 1m of 0.5mm² cable
- 2 year manufacturer warranty

Technical Details
Frequently Asked Questions
Is this a stack light tower?
No. It is a single low-profile 50mm dome that changes colour depending on which wire is energised, so one colour shows at a time. For several colours at once, choose the IF5T 3-level tower.
Which colour should I use for which machine state?
IEC 60204-1 assigns red to emergency, yellow to abnormal conditions, green to normal running and blue to mandatory action. White has no assigned meaning, so it is often used for "machine on" or "operator call".
Does it need NPN outputs?
Yes. This version is switched by NPN (sinking) 24V DC outputs. If your PLC has PNP (sourcing) outputs, choose the IF3P024MS30-1.
How is it mounted, and how rugged is it?
It mounts through a 30mm hole with an M30 thread and is rated IP67, so it suits washdown or exposed locations where a lower profile is needed than the 55mm IF5 series.
Does it have a buzzer?
No. For an audible alert as well, choose an IF5 series beacon with buzzer, such as the IF5P024ZM05-1.
Industry Applications
- Food and beverage washdown — IP67 status signal that tolerates regular cleaning
- Compact machines and conveyors — low-profile status where clearance is limited
- Mobile and outdoor equipment — sealed multicolour indication on exposed panels
