The Farnell 170-839 Reed Proximity Switch is a versatile and reliable sensing device designed for use in various applications where non-contact sensing is required. This proximity sensor, manufactured by the renowned brand OMRON, operates on the principle of induction, where an alternating magnetic field is generated between two opposing reeds to detect the presence or absence of a ferrous metal object.
The sensor housing is made of durable and corrosion-resistant plastic, ensuring a long service life even in harsh environments. The sensing distance of the 170-839 Reed Proximity Switch can be adjusted by changing the position of the magnet or ferrous object, making it an ideal solution for applications where object detection requirements vary.
The switch has a normally open (NO) contact configuration, which means it is not conductive when no object is detected. Once a ferrous metal object enters the sensing range, the proximity switch is activated, closing the internal contacts and completing the circuit. This feature makes it suitable for use in various automation applications, such as machine control, vending machines, or conveyor systems.
The Farnell 170-839 Reed Proximity Switch is a low-power device, consuming only 14mA at 12V DC, ensuring minimal power consumption and reduced energy costs. It features a compact size of 24.6mm (L) x 17.2mm (W) x 15.2mm (H), making it suitable for installation in confined spaces.
The switch can be easily wired using the provided 3-pin terminal block, and it comes with a 50mm cable length for added flexibility in installation. The operating temperature range for the Farnell 170-839 Reed Proximity Switch is from -10 C to 50 C, making it suitable for a wide range of applications in various industries.
In summary, the Farnell 170-839 Reed Proximity Switch is a robust, adjustable, and energy-efficient sensing device perfect for applications requiring non-contact detection of ferrous metal objects. Its compact size, low power consumption, and easy wiring make it a versatile and cost-effective solution for various automation projects.
The Farnell 170-839 Reed Proximity Switch is an electronic component used for sensing the presence or absence of ferrous materials within a certain range. This switch operates on the principle of inducing an electrical current when a ferrous object comes close to it. Here are some pros and cons of using this component in your projects:
Pros:1. High Sensitivity: The Farnell 170-839 Reed Proximity Switch has a high level of sensitivity, making it suitable for detecting small ferrous objects.
2. Compact Size: This switch has a compact size, making it easy to install in various applications.
3. Durable Design: The switch has a rugged design that can withstand harsh environments and can operate in temperatures ranging from -25 C to 85 C.
4. Low Power Consumption: The switch consumes very little power, making it an ideal choice for battery-operated devices.
5. Versatile Applications: The Farnell 170-839 Reed Proximity Switch can be used in various applications, including automotive, industrial, and domestic appliances.
Cons:1. Limited Detection Range: The switch can only detect ferrous materials within a limited range, and it may not be suitable for detecting non-ferrous materials or objects that are too far away.
2. Fragile Reed Contacts: The reed contacts in the switch are delicate and can be damaged if the switch is subjected to shock or vibration.
3. Requires a DC Power Source: The switch requires a DC power source to operate, which may not be convenient for all applications.
4. Limited Operating Frequency: The switch has a limited operating frequency, which may not be suitable for high-speed applications.
Conclusion:The Farnell 170-839 Reed Proximity Switch is a versatile and sensitive component that can be used in a wide range of applications. Its compact size, durability, and low power consumption make it an ideal choice for various projects. However, its limited detection range, fragile reed contacts, requirement for a DC power source, and limited operating frequency are some factors that may limit its suitability for certain applications.
Recommendation:If you require a component for detecting ferrous materials within a limited range and can provide a stable DC power source, then the Farnell 170-839 Reed Proximity Switch is an excellent choice. However, if you need to detect non-ferrous materials, objects at a greater distance, or require a higher operating frequency, then you may need to consider alternative sensing technologies, such as ultrasonic or infrared sensors.
