Omron A4E Series Safety Enabling Switch, 3 Position, 2 NO/1 NC, IP65

This safety enabling switch is a three-position device designed to provide hand-operated enable and release control for safer robot and machine operation. It is intended for integration into control circuits where a tactile enable function and a direct-opening release are required, and is suitable for mounting in multiple orientations to suit pendant or panel layouts.

• Two normally-open and one normally-closed contact configuration provides distinct control outputs
• Reset function is OFF OFF momentary to ensure clear reset action
• Solder terminals permit Compact board or harness connections
• Rated for 125V and 1A for use with low-voltage control circuits
• Mechanical life of 1 million operations supports long-term duty cycles
• Ambient operating range -10°C to 55°C allows use in typical industrial environments

• Suitable for enabling operator control on collaborative robot pendants
• Ideal for machine-tool pendant deadman and enabling circuits
• Used for safety interlock monitoring where direct-opening is required
• Can be used in control panels requiring Compact enable switches

It carries standards-based approvals to align with common industrial control requirements and recognised testing protocols.

A rubber-sealed variant is available offering an IP65 degree of protection for locations exposed to dust or spray.

Solder terminals are specified

The device supplies multiple outputs to separate enable and release monitoring circuits, with dedicated contacts allocated for each function.

The mechanism is specified for high mechanical endurance and defined electrical operation counts to match repetitive use in automation environments.
