Snap action, limit switches are electro-mechanical devices typically used to detect the opening and closing of doors, hatches, and in some cases of pressure or level in industrial approved enclosures. Gunnebo’s GLDB03A2Y model is a three-pole snap action, limit switch consisting of two normally open (NO) and one normally closed (NC) contacts. This contactor is designed to fit a variety of applications.

Application field

The GLDB03A2Y is designed to disconnect the electrical supply to a contactor when a door or hatch is opened or closed and to operate when pressure against the contactor is greater than the factory-set limit. It can be used in commercial and industrial applications requiring a durable and reliable switch. These contactors feature a 2-stage contactor with an integrated circuit breaker that can be manually activated or automatically activated from a 3-pole contactor.

It can be used in various applications such as factory doors and hatches, safety guards, motion control systems, and pressure and level detection. The component’s design is constructed to meet UL, CSA and CE certifications, so it is designed to perform with maximum reliability.

Working Principle

GLDB03A2Y’s snap-action, limit switch utilizes solid-state components with a latch mechanism that is activated when pressure is applied to the contacts. When one of the three phases is activated, the contactor is energized and the contacts are activated. The normally open contacts remain open until the pressure is removed, and the normally closed contacts remain closed until the pressure is increased.

When the limit switch is activated, it can be used to signal the user when the contactor is open or closed. It can also be used to signal the user when a pressure or level exceeds the defined limit. A signal is then sent to the controller, which causes the motor to be energized or de-energized as necessary.

The GLDB03A2Y contactor is designed for use in multiple applications and can operate in a variety of environments. It is a reliable and durable component that ensures safety and flexibility in the workplace.
