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

Omron A4E Series Safety Enabling Switch, 125V Contact Voltage, 2 NO/1 NC Contact Configuration - A4E-B200HS

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.

Features & Benefits

• 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

**Applications**

• 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

What approvals support use in industrial control panels?

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

How is environmental protection provided for harsher sites?

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

What wiring method is required for reliable connections?

Solder terminals are specified
recommended soldering practices and flux types should be followed to avoid thermal or mechanical damage.

How many switching outputs does the unit provide and how are they arranged?

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

What durability can be expected under frequent switching?

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