AH166261-A

Snap action, limit switches are electromechanical devices that are used in industrial automation applications to detect the presence of objects. The AH166261-A is one such limit switch made by Allen-Bradley. It is a small and compact limit switch with a mouse ear actuator design for easy installation. The AH166261-A has an adjustable operating force that ranges from 0.195 to 0.735 lbs, making it suitable for most industrial application needs.

Features of AH166261-A Limit Switch

• Compact, mouse ear actuating design
• Adjustable operating force
• Temperature rating of -60~93°C
• Dust proof and rust-proof
• IP67 rated and UL approved

Application and Working Principle

The AH166261-A snap action, limit switch is designed to be used in industrial automation applications. It is mostly used to detect the presence of objects in a particular area. When the limit switch is activated, an electrical signal is sent to the controlling system that serves as an alert that the object has been detected.

The operating principle of the AH166261-A limit switch is based on the snap-action principle. When the limit switch is triggered, a metal disc is set into motion on its supporting spring. This causes the disc to move rapidly, over-riding the inertia caused by the operating force. This rapid displacement of the metal disc snaps the actuator open or close, and the switch is switched on or off. The switch remains in this position until it is disturbed again by the operating force.
