HE1G-L Grip Style Three-position Enabling Switches
The distinctive tactile feedback makes it easy to know the current position of the switch.
Light operating force ideal for long-hour operation
Ergonomically-designed OFF-ON-OFF operation.•
The switch does not turn ON when being released from position 3 •
(OFF when pressed) to position 1 (OFF when released) (IEC 60204-
1, 9.2.5.8).
Two contacts areprovided so that even if one contac fails due to •
welding or short-circuit, the other contact can disable machine
operation.
Monitor switch is direct opening action.•
The distinctive tactile feedback when shifting to position 2 (enabling •
position) makes it easier to know where the enabling switch is
currently positioned—position 1 (OFF), 2 (ON), or 3 (OFF).
Lighter operating force on position 2 assures more comfortable, •
stress-free operation when operating long hours.
Emergency stop switch and momentary pushbutton versions are •
available.
Screw terminal and internal connector models can be selected.•
IP66 degree of protection (HE1G-L21SM)•
HE2B enabling switch is installed ( •
).

Note 1: Silicon rubber: Can be used in general factories. Remains fl exible at cold temperatures. Suitable to applications in a wide operating temperature range.
Note 2: NBR/PVC polyblend: Oil-proof. Suitable for environments subjected to machine oil and painting robot where silicon rubber cannot be used.
