HE5B ø16mm Round Three-position Enabling Switches
Round-shaped operator for ø16 mm mounting hole.
3-position enabling switch with two contacts, ideal for installing in small teaching pendants.
• Ergonomically-designed OFF-ON-OFF operation.
• Easy recognition of position 1 to 2 transition is made possible by
a snap action switch.
• Sufficient difference in operating force is provided for shifting
from posi tion 2 to position 3.
• Low pressure is required to maintain position 2, allowing long-
time oper ation.
• Grip style enabling switch housing available.
• The switch does not turn ON when being released from posi-
tion 3 (OFF when pressed) to position 1 (OFF when released)
(IEC60204-1, 9.2.5.8).
• Two contacts are provided in a 3-position enabling switch so
that even if one contact fails due to welding or short-circuit, the
other contact can disable machine operation.
• The waterproof rubber boot provides IP65 protection.
