DG23-B1LA

DG23-B1LA Application Field and Working Principle

The DG23-B1LA, manufactured by Omron, is a subminiature, snap-action, limit switch. It is small in size and intended for use in applications where space constraints are a major concern. The switch itself is a straightforward single-pole, single-throw (SPST) configuration.

The major features of the DG23-B1LA are its miniaturized size and snap-action switching mechanism. The switch is designed to rapidly snap from its open to its closed position or vice-versa when actuated and is rated for a maximum of 10 million cycles. This snap-action enables the switch to operate in tight spaces, making it suitable for applications such as pilot lights and electronic devices.

The DG23-B1LA also has a unique design for its actuator. The actuator is built into the body of the switch and is made from a durable plastic material. This design enables the switch to operate in colder temperatures (as low as -20°C) and maintains a secure grip even in harsh environments.

The limit switch features a small snap disc with two contact arms extending from its sides. When the switch is actuated, the arms will open, causing an electrical contact to be broken. When the switch is released, the arms will snap back, causing the contact to be closed again. This is referred to as "snap-action" because it enables the switch to operate quickly and reliably.

The DG23-B1LA also features an adjustable travel of up to 1.2mm, enabling it to be suited to any application where precise actions are required. The switch also has a maximum operating voltage of 250 VAC and can withstand high levels of shock and vibration.

The DG23-B1LA is a versatile, reliable, and cost-effective switch for applications where space constraints are a major issue. It is particularly useful for situations where a limited number of operations are to be performed and where reliability is paramount.
