D40A-1C5

The Omron D40A-1C5 Magnetic Reed Switch is a versatile and reliable door sensor designed for use with 24VDC applications. This switch comes as a single piece, allowing you to integrate it into various door opening systems with ease.

The D40A-1C5 is a magnetic reed switch, which means it utilizes the principle of a magnetic field to detect the position of an object. In this case, it's designed to detect when a door or cover is open or closed. The switch consists of two parts a fixed contact and a movable contact separated by a small air gap. When the magnetic field is present, the switch is closed. Once the magnetic field is removed, such as when the door is opened, the switch opens.

This Omron switch is suitable for industrial automation, safety systems, and any other application where you need to monitor the opening and closing of a door or cover. It can be used with doors up to 5 meters (16.4 feet) wide, making it a great choice for larger doors or gates.

The Omron D40A-1C5 Magnetic Reed Switch is built to last, featuring a rugged design that can withstand harsh environments. It is rated for an operating temperature range of -40 C to 70 C (-40 F to 158 F), ensuring stable operation under various temperature conditions. Additionally, it is compliant with RoHS and REACH directives, which makes it an environmentally friendly choice.

Installing the switch is simple and straightforward, and it comes with mounting screws and a terminal block to make the wiring process easier. The terminal block accepts 5.0-10.5mm (AWG 18-14) wires, providing ample space for secure connections.

Overall, the Omron D40A-1C5 Magnetic Reed Switch is a high-quality, reliable, and versatile component for monitoring door openings in industrial, automation, and safety applications. Its rugged design, wide temperature range, and easy installation make it an excellent choice for various projects.

The Omron D40A-1C5 magnetic reed switch is a commonly used sensor for detecting the opening and closing of doors or other types of applications. Here are some pros and cons of buying this particular model:

1. Reliable: Magnetic reed switches are known for their reliability and durability, making them a popular choice for various applications.

2. Easy to Install: The switch is simple to install and can be used with wires or terminals. It is also available in various lengths, allowing for flexibility in installation.
