402EN66-6

Snap Action, Limit Switches

402EN66-6 is a snap action, limit switch. It has a broad range of industrial applications including position and speed control for conveyors and lifting equipment, door and window protection, emergency stop system and safety control. It is designed with a robust die-cast zinc-alloy housing and stainless-steel components for long working life even in harsh industrial environments.

402EN66-6 offers two distinct primary functions—normally open (NO) and normally closed (NC) switching modes. In the normally open (NO) mode, the switch is closed (ON) when actuated, while in the normally closed (NC) mode, it remains off (OFF) when actuated.

The 402EN66-6 utilizes a plunger actuator that presses against the switch’s internal contact points to register an action. When the plunger is forced into the switch, it actuates a contact point, which completes an electrical circuit, which in turn sends a signal to another control system. The same plunger is also connected to a snap-action switch, which allows for a swift on/off toggle when actuated.

In order for the switch to accommodate for different levels of physical movement, its travel distance and trip point setting can be adjusted through the use of a setting screw. This allows for a more accurate on/off electrical contact, depending on the setting.

Overall, the 402EN66-6 is an ideal snap-action, limit switch for industrial applications aspiring for a reliable, cost-effective and robust switch. It utilizes a lever-style design that helps ensure a quick and reliable electrical contact; the adjustable travel and trip point settings allow for a customized on/off response; and the die-cast zinc-alloy housing provides enhanced durability for heavy-duty conditions.
