Reed Switch Set for Pneumatic Cylinders
The SPEEDAIRE reed switch set is designed for use with pneumatic cylinders that have bore diameters of 50, 63, 80 and 100 mm. It provides position sensing for automation systems that require a compact solid-state switch with an NPN output and a two-wire connection. The IP67 enclosure rating allows installation in environments where dust and temporary water immersion occur.
Electrical Limits and Cable Length
Switching current is limited to 40 mA maximum at 24 V DC, so the device must only drive compatible low-current inputs such as PLC discrete modules or relay coils. The 10 ft lead length fixes the maximum distance between the cylinder and the controller unless an approved extension is added. Operating temperature range spans 14 to 140 degrees F, which restricts use in processes that exceed these limits.
Compatibility Checks Before Ordering
Verify that the cylinder bore matches one of the listed diameters and that the control system accepts an NPN sinking signal with a two-wire interface. Confirm the supply voltage is 24 V DC and that the load current stays below 40 mA. Ensure the mounting location stays within the stated temperature range and that the IP67 rating satisfies the site's ingress protection requirements.

Questions about this item
Should I pick the 10 ft lead or a shorter length for my cylinder?
The set comes with a 10 ft lead; choose it if the distance from the cylinder to the controller is close to that length, otherwise a shorter lead reduces excess cable.
What does the 40 mA switching current mean when the switch is wired to my PLC input?
It is the maximum current the reed contact can carry; your PLC input must draw 40 mA or less at 24 V DC to avoid damaging the switch.
How does the IP67 rating limit where I can mount the switch?
IP67 means the switch is dust-tight and survives temporary immersion in water, so it can be mounted in wet or dusty environments but not continuously submerged.
