ual control of a machine
• Provides safety function when user either squeezes or releases
the handlegrip switch
• Ergonomic design with a detented enable position (position 2)
• Terminal 1-2 and 3-4 contacts will not re-close when released
from fully squeezed (position 3)

• Optional momentary pushbutton switch (depending on model)
that can provide hold-to-run, reset, or jogging/inching functions
• Built-in strain relief and M20x1.5 conduit connection
• Meets IP65 or IP66, depending on model
•
Insulated device (IEC 60947-5-1) on all models
• Design meets or exceeds:
ANSI RIA R15.06 and ISO 10218 Robot safety standard

WARNING: Not a Safeguarding Device
An Enabling Device is not considered a safeguarding device, because it requires an overt action
by an individual to stop machine motion.
(A safeguarding device limits or eliminates an individual's ex-
posure to a hazard,
without action by the individual or others.)
Because an individual must actuate the device for it to function, these devices do not fit the definition of a
safeguarding device and cannot be substituted for required safeguarding. Refer to the relevant standards
to determine those requirements.
