902-18 TELEDYNE Reed Relay

Review TELEDYNE Reed Relay

The Teledyne 902-18 Reed Relay is a versatile and robust electromechanical switching solution designed for various applications, particularly in the fields of industrial automation, test and measurement, and telecommunications.

This relay boasts an impressive contact rating of 5 A at 250 V AC or DC, making it suitable for handling moderate currents and voltages. The 902-18 features a total of 18 contacts, arranged in two sets of three normally open (NO) and three normally closed (NC) contacts. Each set has an independent coil, allowing for independent operation of the contacts.

The contacts are made using a reed switch technology, ensuring reliable and long-lasting performance. Reed switches consist of two metal reeds, each with a contact surface. When a magnetic field is applied, the reeds are attracted to each other, closing the contacts. Once the magnetic field is removed, the reeds spring back to their original position, opening the contacts.

The Teledyne 902-18 Reed Relay is compact and easy to integrate into various systems, thanks to its small form factor of 1.9 inches by 2.7 inches (48.3 mm x 68.6 mm). It operates over a wide temperature range, from -20 C to 70 C ( 4 F to 158 F), ensuring stable performance in various environments.

The relay also provides excellent electrical isolation, with a minimum insulation resistance of 100 M between the coil and the contacts, and 500 M between the contacts in the de-energized state. This makes it an ideal choice for applications requiring high isolation between input and output signals.

Additionally, the 902-18 Reed Relay offers fast switching times, with a typical contact making time of 10 ms and contact breaking time of 20 ms. Its low power consumption, with a maximum power dissipation of 0.5 W, further enhances its energy efficiency and extends its operational life.

The Teledyne 902-18 Reed Relay is a reliable, compact, and efficient switching solution that offers excellent performance and versatility for a wide range of applications. Its robust design, combined with its high contact rating and long-lasting reed switch technology, makes it an excellent choice for industrial automation, test and measurement, and telecommunications systems.

The Teledyne 902-18 Reed Relay is a commonly used electromechanical switching device, particularly in applications requiring high reliability and low power consumption. Here are some pros and cons of buying this relay:

1. High Reliability: Reed relays are known for their long operational life due to their solid-state construction. The Teledyne 902-18 Reed Relay has a contact life rating of over 100 million cycles.

2. Low Power Consumption: Reed relays consume less power than other types of relays since they do not require a moving armature. This makes them an excellent choice for battery-powered applications.

3. Compact Size: The Teledyne 902-18 Reed Relay is relatively small compared to other relays, making it ideal for space-constrained applications.

4. Quiet Operation: Reed relays produce minimal noise during operation, making them suitable for applications where silence is crucial.

5. Long Operational Life: The solid-state construction of reed relays leads to a longer operational life compared to other types of relays.

1. Limited Current Handling Capacity: Reed relays have a limited current handling capacity compared to other types of relays. The Teledyne 902-18 Reed Relay can handle up to 1.2 Amps, which may not be sufficient for high-current applications.

2. Limited Voltage Rating: Reed relays have a limited voltage rating. The Teledyne 902-18 Reed Relay has a maximum voltage rating of 100 Volts.

3. Limited Operating Temperature Range: Reed relays have a limited operating temperature range, which may not be suitable for extreme temperature applications.

4. Sensitive to Magnetic Fields: Reed relays can be affected by strong magnetic fields, which may cause the contacts to close or open unintentionally.

5. Limited Availability of Accessories: Reed relays may not be as widely available as other types of relays, making it more challenging to find accessories such as mounting kits or terminal blocks.

In conclusion, the Teledyne 902-18 Reed Relay is an excellent choice for applications where high reliability, low power consumption, compact size, and quiet operation are essential. However, it may not be suitable for applications requiring high current handling capacity, high voltage rating, or extreme operating temperatures.

Recommendation: If your application requirements align with the pros of the Teledyne 902-18 Reed Relay, then it is an excellent choice. However, if you require a higher current handling capacity, higher voltage rating, or operate in extreme temperatures, you may need to consider other types of relays. It is always recommended to consult the relay datasheet and application notes to ensure it meets your specific requirements.
