Omron D4A-0005N Operating Head for Limit Switch

The Omron D4A-0005N is an operating head for limit switches that features maintained contact and side-rotary actuation. This component functions as the actuating extension of a limit switch, triggering a latched, kept-on signal when engaged by a moving part. The maintained contact configuration ensures the switch remains closed after actuation until the reset occurs, making it suitable for control circuits that require a held state. The side-rotary orientation describes how the actuator presents itself to the switch, influencing mounting, clearance, and how the actuator interfaces with equipment in compact layouts. Identified by the model number D4A-0005N, this operating head is part of Omron's limit switch hardware ecosystem and is used where a precise, latched actuation is required in automation and machine control environments.
