MOUNTING DIRECTIONS
for Magnetic Reed Switch Assemblies
1. Insert switch cable through top of mounting bracket.
2 .Orient bracket with respect to cylinder so that set screws
are located on side most convenient.
3 .Slide switch into bracket with end containing indicator light
towards center of cylinder. Bracket contains a register pin
which must be mated with slot in switch. When mounting
switches on rotary actuators make sure that the powered
piston is used for signal. Pistons are not attached to gear
rack which sometimes allow piston on exhaust side to move
ahead of the actual rotation.
4. Hook bracket over one tierod and push assembly against
cylinder until the side with the set screws rests against the
other tierod. (Make sure set screws are clear of tierod.)
Tighten set screws until they contact firmly underneath tierod
Then loosen enough to enable switch and bracket assembly
to slide along cylinder tube.
5. Locate switch assembly where desired and lock in place by
tightening set screws. (This step is normally performed after
all electrical connections have been made. Indicator light
will then show at what point switch contacts are actually
closed.)

SHOCK RATING
The basic switch can withstand up to 60 G maximum in the direction of
contact closure without misfire or malfunction.
Some general use relays and valve solenoids have a potential to
prematurely fail reed switches due to electrical transients. A commercially available transient voltage suppressor called a Tranzorb has proven to
be effective in reducing this potential failure. This substantially increases
the life of PHD Reed Switches.
The following Tranzorbs may be used with relay coils or valve solenoids
and are listed with respect to nominal coil voltages.

VIBRATION SENSITIVITY
Switch will withstand vibration amplitude of 30 G at frequencies up to
6000 Hz without misfire. False operation can occur at vibration frequency levels higher than 6000 Hz.
OPERATING TEMPERATURE
40°F to +150°F for standard cable.
CABLE SPECIFICATION
The conductors are tinned copper with polyethylene insulation. Conductors are cabled with a rayon braid, a tinned copper braided shield,
and a chrome vinyl jacket which is resistant to hydraulic fluids.

Tranzorb listed will protect switch under normal conditions. If abnormally
high level transients exist additional Tranzorbs may be necessary. Tranzorbs do not change switch rating.
