The D4N-4287 has a number of applications in a variety of industries. It is a snap action, limit switch designed for use in harsh, industrial environments. This non-contact switch offers reliable detection of a wide range of operating conditions, including extreme vibration, wide temperature ranges, and hazardous locations. This versatile switch can be used for machine and product control, position feedback, and status indication.

The D4N-4287 switching mechanism is designed for specific actions to indicate the presence or absence of a given item, action, or condition. A wire form actuator is used to provide an audible “click” as the contact opens or closes. This signal is transmitted to the output contacts of the switch enabling remote or local signal conditioning or response.

This switch operates via a single movement of the actuator, which closes or opens two sets of contacts. The operating force of the actuator is adjustable from 20 to 100 grams and the operating angle is adjustable from 15° to 45°. The operating life of the switch is approximately 50,000 cycles with a maximum switching frequency of 10 operations per second. The switch is rated for an operating temperature range of -15°C to +85°C.

The D4N-4287 is a robust, reliable, industrial rated switch that’s built to withstand the most demanding working conditions. It has a variety of options available to match the needs of any specific application. The two sets of contacts can be connected with a mechanical bridge or relay to provide both positive-opening and positive-closing switching. The switch is also available in a two-pole configuration, with two sets of contacts, which can be used to detect a variety of operating conditions.

In addition to its various features, the D4N-4287 provides IP67 protection and a variety of environmental seals for harsh environmental conditions. It also offers an optional diode in series with the output contacts, preventing current from flowing back into the switch when the contacts open. The switch can also be integrated with accessories such as a limit stop to prevent excessive movement of the actuator and to provide additional safety.

The D4N-4287 is designed for a wide range of snap action, limit switch applications. It’s suitable for machine and product control, position feedback, and status indication. It offers reliable contact operation, adjustable operating force and angle, an operating temperature range of -15°C to +85°C, IP67 protection, and optional diode protection. The switch offers a long operating life and robust operation in the most demanding applications.
