Enabling Switches
HE1G Basic Grip Enabling Switch
Key features:
• 3 position functionality (Off – On – Off) as required for manual robotic control
OverviewXW Series E-StopsInterlock SwitchesEnabling SwitchesSafety Control RelaysLight CurtainsAS-Interface Safety at Work
• Ideally suited for use as an enabling (aka “deadman”) switch for robotic cells
• Provides a high level of safety based on human behavioral studies that determine
personnel may squeeze OR let go when presented with a panic situation
• Contacts will not re-close when released from Off On (3 1) (per IEC60204-1; 9.2.5.8)
• Optional E-Stop switch built in
• Connection for conduit and cable strain relief built in
• IP66 waterproof sealing
• Meets ANSI RIA 15.06 robotics standards
• Optional momentary pushbutton or E-Stop built in
(HE1B installed)

Enabling Switches
Notes:
1. 3-position switches operate with direct opening action
2. For the output of the enabling device, use terminals 1-2 and 3-4.
3. The above operation characteristics show when the center of the button is pressed. Pressing the edge of a button turns on one contact
earlier than the other contact, causing a delay in operation.
