HE1G Grip Style Three-position Enabling Switches
Ergonomically designed grip style enabling switch with two 3-position enabling switches.
• Ergonomically-designed OFF-ON-OFF operation.
• Direct opening action mechanism for shifting from position 2
(ON) to position 3 (OFF) (EN 60977-5-1/IEC 60947-5-1, Annex
K).
• 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 so that even if one contact fails due
to welding or short-circuit, the other contact can disable ma-
chine operation.
• Emergency stop switch and momentary pushbutton versions are
available.
• Cable gland supplied.
• HE1G-21SM is IP66 waterproof.
• Can be used for applications required by the ANSI robot stan-
dard.
