HE2B
HE2B Redundant (Double) Basic 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 enabling (aka “deadman”) switch on teach pendants
• 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
• Snap acting contacts from Off On (1 2)
• Positive action contacts from On Off (2 3) ensure no contact welding (per
EN60947-5-1 / IEC60947-5-1)
• Contacts will not re-close when released from Off On (3 1) (per IEC60204-1;
9.2.5.8)
• Multiple contacts for enhanced reliability
• Monitoring contacts in addition to main load contacts
• Available with or without rubber cover (cover provides IP65 watertight seal)
