HE3B ø16mm Rectangular Three-position Enabling Switches
Rectangular operator part with ø16 mm mounting for easy installation.
2-contact 3-position enabling switches ideal for installing in small teach 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 position 2 to position 3.
Low pressure is required to maintain in position 2 allowing for •
longtime operation.
Reliable operation is assured even when the edge of the operator •
button is pressed.
The switch does not turn ON while being released from position 3 •
(OFF) to position 1 (OFF) (IEC60204-1, 9.2.5.8).
Two contacts are provided in a 3-position enabling switch so that •
even one contact fails due to welding or short-circuit, the other
contact can disable machine operation.
The waterproof rubber boot provides IP65 protection. •
