SPEEDAIRE 6KL75 Reed Switch N/O SPST
A reed switch for bore diameters 3/4 to 2-1/2 inches, N/O SPST with NEMA 4 enclosure, switching up to 30 mA at 5-120V AC/DC
- Normally open SPST function simplifies control wiring
- Reed switch design offers reliable magnetic actuation
- 30 mA maximum switching current suits low-power circuits
- 5–120 V AC/DC range fits diverse supply voltages
- NEMA 4 enclosure protects against dust and water ingress
What It Is
The SPEEDAIRE 6KL75 is a two-wire reed switch with normally open SPST function. It handles up to 30 mA switching current across 5 to 120 V AC/DC. The NEMA 4 enclosure suits industrial environments needing a compact magnetic position sensor.
Upgrade Path
This switch replaces mechanical limit switches where contact bounce or wear causes unreliable signals. The jump is worth it when you need solid-state actuation without moving parts and can work within the 30 mA current limit. Buyers who need higher switching current cannot use this device.
Practical Limits
Operation is restricted to cylinder bore diameters from 3/4 to 2-1/2 in. The two-wire design requires a compatible control input that sources the load current through the switch. Voltage must stay between 5 and 120 V AC/DC, and the 30 mA ceiling limits direct drive of larger relays or contactors.

Questions about this item
What bore diameter range does the SPEEDAIRE 6KL75 reed switch fit?
The switch mounts on cylinders with a bore diameter from 3/4 to 2-1/2 inches.
How do I wire the two-wire reed switch, and what is the common mistake?
Connect the two leads in series with the load; the common mistake is applying voltage without a load, which can exceed the 30 mA maximum switching current.
When should the reed switch be replaced in normal service?
Replace the switch if it fails to actuate reliably or if the NEMA 4 enclosure shows damage that could allow moisture ingress.
