EPOS2 70/10 – DigIN4…6 / Proximity Switches
Best Practice
• Preferably, use 3-wire PNP proximity switches.
• Using 3-wire NPN proximity switches requires an additional pull-up resistor.
R ext
(12 V) = 560 Ω (300 mW)
R ext
(24 V) = 3 kΩ (200 mW)
• By principle, using 2-wire proximity switches is possible.
