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.
Suffi cient difference in operating force is provided for shifting •
from posi tion 2 to position 3.
Low pressure is required to maintain position 2, allowing longtime •
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. •
