RA-400112-DN-BX COLE HERSEE Relay Diode Bracket

Review COLE HERSEE Relay Form 12v Diode Bracket

The Cole Hersee Ra-400112-DN-BX is a versatile 12V DC coil operated relay with a diode bracket. This device is designed to handle a maximum current of 30 Amperes and a maximum voltage of 28V DC. It comes with a form C normally open contact and a form A normally closed contact, providing flexibility for various circuit applications.

The relay is housed in a robust die-cast aluminum case, ensuring durability and reliability. The dimensions of the case are 2.6 inches in length, 1.8 inches in width, and 1.1 inches in height, making it a compact yet powerful addition to any electrical system.

The diode bracket of this Cole Hersee relay is designed to protect against inductive voltage spikes. It includes four diodes, each with a 50V maximum reverse voltage rating. These diodes ensure that the coil is not subjected to back EMF when the contacts open, thereby extending the life of the relay and protecting the connected circuitry.

The Cole Hersee Ra-400112-DN-BX relay features a gold-plated contact surface for enhanced conductivity and longer contact life. It also comes with a clear plastic cover over the contacts, which allows for easy visual inspection of the contacts and helps to prevent contamination.

This relay operates at a contact bounce rate of less than 3ms, ensuring smooth and reliable switching. It also includes a built-in coil overvoltage protection mechanism, which automatically disconnects the coil when the voltage exceeds a certain threshold, preventing damage to the relay.

The Cole Hersee Ra-400112-DN-BX is designed for easy installation. It comes with mounting holes on the case for securing it to a surface, and the wiring terminals are clearly labeled and easily accessible. The relay is also RoHS compliant, making it an eco-friendly choice for electronic applications.

In summary, the Cole Hersee Ra-400112-DN-BX is a reliable and robust 12V DC coil operated relay with a diode bracket. It is designed for heavy-duty applications, with a high current capacity, long-lasting contacts, and built-in overvoltage protection. Its compact size, easy installation, and versatile contact configuration make it a valuable addition to any electrical system.

The Cole Hersee Ra-400112-DN-BX relay is a 12V, SPDT (Single Pole Double Throw) relay with a diode bracket. Here are some pros and cons that might help you decide whether to purchase it:

1. SPDT Relay: This type of relay is suitable for applications where you need to switch between two circuits.

2. 12V Operation: It can be used in a wide range of applications where a 12V power source is available.

3. Diode Bracket: The diode bracket protects the relay coil from voltage spikes that may damage it. It also enables the relay to act as a one-way switch, allowing current to flow in only one direction.

4. Compact Size: The dimensions of the relay are fairly small, making it a good option for applications where space is limited.

5. Durable Construction: Cole Hersee is known for producing high-quality relays with robust construction that can withstand harsh environments.

1. No Indicator Light: The relay does not come with an indicator light, which may make it more difficult to troubleshoot or monitor the status of the circuit.

2. Limited Current Rating: The relay is rated for a maximum current of 10A, which may not be sufficient for high current applications.

3. Lack of Documentation: The datasheet for the relay is not very detailed, which may make it more challenging to use in complex applications.

In conclusion, the Cole Hersee Ra-400112-DN-BX relay is a good option for applications where you need to switch between two circuits and require protection from voltage spikes. Its compact size, durable construction, and diode bracket are additional advantages. However, the lack of an indicator light and limited current rating may be drawbacks for some users. Ultimately, the decision to purchase this relay depends on the specific requirements of your application.

If you are looking for a reliable and compact 12V SPDT relay with a diode bracket, the Cole Hersee Ra-400112-DN-BX is a solid choice. However, if you require a higher current rating or an indicator light, you may need to consider alternative options.
