Review TELEDYNE RELAYS Nos Hermetically Sealed To-5 Relay 18vdc Dpdt Gold Contacts

The Teledyne Relays 712-18 hermetically sealed TO-5 relay is a robust and reliable solution for applications that require high performance and reliability in harsh environments. This 18-piece relay set comes with 18 individual relays, each having a compact TO-5 packaging that measures 18.4mm x 14.7mm x 10.2mm.

The hermetically sealed design of these relays ensures that they are completely protected against dust, moisture, and other contaminants, making them ideal for use in industrial, automotive, and aerospace applications. Each relay can handle a contact rating of up to 5 amperes at a maximum voltage of 18 volts DC.

The 712-18 relays feature gold-plated contact pins that provide excellent electrical conductivity and ensure a long contact life. They also have a low contact resistance of 25 milliohms, which minimizes power loss and reduces the risk of arcing.

The relays have a switching time of 35 milliseconds, making them suitable for fast-switching applications. They also have a low coil resistance of 25 ohms, which minimizes the power required to switch the relay.

Each relay has a coil voltage of 12 volts DC and a maximum coil current of 250 milliamperes. They have a contact bounce time of less than 10 microseconds, which minimizes the effect of contact bouncing on the output circuit.

The 712-18 relays have a operating temperature range of -55 C to 125 C, which makes them suitable for use in a wide range of temperature environments. They also have a maximum coil temperature of 125 C, which ensures that they can handle high temperatures without damaging the coil.

These relays have a low power consumption of less than 0.2 watts per relay when inactive, making them an energy-efficient solution for applications where power consumption is a concern. They also have a low electromagnetic interference (EMI) and radio frequency interference (RFI) emission, which minimizes the risk of interference with other electronic devices.

The 712-18 hermetically sealed TO-5 relays from Teledyne are available with a variety of connection options, including screw terminals, PCB pins, and solder pads, making them easy to integrate into various systems and applications. They are also RoHS compliant and meet the requirements of various industry standards, including MIL-PRF-27, MIL-PRF-19602, and UL547C.

Teledyne Relays, specifically model 712-18 hermetically sealed TO-5 relays with 18VDC contacts, are commonly used in various industrial applications due to their rugged design and high reliability. In this analysis, we will discuss the pros and cons of buying these relays to help you make an informed decision.

1. High Reliability: These relays are known for their excellent reliability, making them a popular choice in critical applications where failure is not an option. They are hermetically sealed, which means that they are completely enclosed in a gas-tight package, protecting the internal components from external contaminants and ensuring long-term operation in harsh environments.

2. Robust Design: The TO-5 relay package provides excellent thermal management, which is essential for high power applications. The relay contacts are rated for 18VDC, making them suitable for use in applications with higher voltage requirements.

3. Wide Operating Temperature Range: These relays can operate in a wide temperature range (-40 C to 85 C), making them suitable for use in various industrial environments.

4. Low Power Consumption: These relays have a low power consumption, which can help reduce energy costs and prolong battery life in applications where power is limited.

1. Cost: Teledyne Relays are generally more expensive than other relays due to their high-performance features and rugged design. The cost may be a significant factor for some buyers, especially for large quantities.

2. Limited Availability: These relays may not be readily available from all distributors, which could lead to longer lead times for procurement.

3. Complexity: These relays may require more complex wiring and installation compared to standard relays due to their hermetic seal and TO-5 packaging.

In conclusion, Teledyne Relays, model 712-18 hermetically sealed TO-5 relays with 18VDC contacts, offer several advantages, including high reliability, robust design, wide operating temperature range, and low power consumption. However, they come with some disadvantages, such as higher cost, limited availability, and complexity.

If your application requires a high-performance, rugged relay that can operate in harsh environments and withstand high power requirements, these Teledyne Relays are an excellent choice. However, if cost is a significant factor, or if you can use a standard relay with similar specifications, it may be more cost-effective to consider other options. In any case, it is recommended to consult with a relay expert or distributor to determine the best solution for your specific application.
