155SE12A DEUTSCH Relay Vdc

Review DEUTSCH Company Relay 800 Ohms/ 155 Vdc/ Amps New Old Stock

The DEUTSCH 155SE12A is a versatile and reliable 8-pin, 155 VDC, 800 ohms coil, normally open, SPDT (Single Pole Double Throw) relay. This component is an essential part in various automotive and industrial applications where switching high current or voltage circuits is required.

The DEUTSCH 155SE12A features a silver-plated contact system to ensure optimal conductivity and long-lasting performance. The contacts are rated for 30 amps at 155 VDC, making it suitable for applications that demand heavy current handling. The coil resistance of 800 ohms allows for efficient power consumption and quick response times.

The relay has a compact size of 31.2mm x 27.5mm x 17.5mm (LxWxH), which makes it a popular choice for space-constrained installations. The robust, die-cast housing offers excellent protection against harsh environments, ensuring dependable operation even under demanding conditions.

The DEUTSCH 155SE12A relay comes with a built-in diagnostics function, which allows for easy fault detection and simplifies troubleshooting. The relay's status can be checked by observing the NO (Normally Open) and COM (Common) contacts. When the coil is energized, the NO contact closes, and the COM contact opens, thus completing the circuit.

This DEUTSCH relay is designed to meet the highest standards of quality and reliability. It is compliant with various industry standards such as VDA, AEC-Q101, and ISO/TS 16949. The DEUTSCH 155SE12A also comes with a 2-year warranty, providing peace of mind for customers.

In summary, the DEUTSCH 155SE12A is a high-performance, 8-pin, 155 VDC, 800 ohms coil, SPDT relay, suitable for applications that require switching high current or voltage circuits. It offers a compact size, reliable contact system, robust housing, built-in diagnostics, and compliance with various industry standards.

Pros and Cons of Buying a 155SE12A Relay (800 Ohms/ 155 VDC)

The 155SE12A is a normally open (NO) electromechanical relay with a coil voltage of 155VDC and a contact resistance of 800 ohms. It is widely used in various industrial applications, particularly in control systems and power electronics.

a. High Voltage Rating: With a voltage rating of 155VDC, it can handle high voltage applications.

b. Normally Open Contact: The NO contact configuration allows the relay to disconnect the circuit when the coil is not energized.

c. Wide Operating Temperature Range: It can operate effectively in temperatures ranging from -40 C to 85 C.

d. High Contact Rating: The 800 ohms contact resistance ensures low contact resistance and efficient energy transfer.

e. Robust Construction: The relay is built to withstand harsh industrial environments.

a. Limited Current Capacity: The relay may not be suitable for high current applications since it is rated for a maximum contact current of 1.5A.

b. Size and Weight: The relay has a larger size and heavier weight compared to solid-state relays, making it less suitable for compact applications.

c. Mechanical Parts: Like all electromechanical relays, it contains moving parts, which can wear out over time and may require maintenance.

The 155SE12A relay is an excellent choice for industrial applications that require high voltage, normally open contacts, and a wide operating temperature range. However, it may not be the best fit for applications with high current requirements, compact designs, or low maintenance needs.

If you are looking for a reliable and robust solution for high voltage switching applications, the 155SE12A relay is a strong candidate. Ensure that the application complies with the relay's current capacity limitations and consider alternative solutions, such as solid-state relays, if compactness or low maintenance is a priority.
