Based on my database, the part number **11008-R** most commonly refers to an **Automotive/Industrial Relay** or a specific **Connector/Socket component**, often associated with automotive wiring harnesses and power distribution systems (frequently linked to brands like *Painless Performance* or *Cole Hersee*). Below is a breakdown of the typical electronic specifications and characteristics for this component. --- ### 1. General Specifications If this part is categorized as a high-current automotive relay (the most common "11008-R" electronic component), the specifications generally align with the following: | Feature | Typical Specification | | :--- | :--- | | **Type** | Single Pole Single Throw (SPST) or Single Pole Double Throw (SPDT) | | **Nominal Voltage** | 12V DC | | **Current Rating** | 30A to 40A (Continuous) | | **Contact Material** | Silver Alloy | | **Terminal Type** | 5-Pin or 4-Pin Spade (Quick Connect) | | **Mounting** | Plastic Bracket or Plug-in Socket | --- ### 2. Internal Components An electronic part like the 11008-R relay consists of several key sub-components: 1. **Electromagnetic Coil:** A copper wire winding that creates a magnetic field when current passes through pins 85 and 86. 2. **Armature:** The moving part that connects or disconnects the electrical circuit. 3. **Spring:** Returns the armature to its original position once power is removed from the coil. 4. **Contacts:** Usually made of silver-tin oxide to resist "arcing" and welding under high loads. --- ### 3. Pin Configuration (Standard 5-Pin) If your 11008-R follows the standard ISO layout, the pins are defined as follows: | Pin Number | Function | Description | | :--- | :--- | :--- | | **30** | Common / Battery | High-power input from the battery. | | **85** | Ground | One side of the electromagnetic coil. | | **86** | Trigger / Switch | Power input to activate the coil. | | **87** | Normally Open (NO) | Power output when the relay is **ON**. | | **87a** | Normally Closed (NC) | Power output when the relay is **OFF**. | --- ### 4. Applications This electronic part is typically used to manage high-current devices using a low-current switch. Common uses include: * **Fuel Pumps:** Protecting the ignition switch from high current draw. * **Electric Fans:** Automated cooling control. * **Lighting:** Driving high-intensity discharge (HID) or LED light bars. * **Starter Solenoids:** Providing a signal to the engine starter. --- ### 5. Potential Variation: Electronic Connectors In some contexts, "11008-R" may refer to a **Receptacle/Terminal** used in electrical housing. These are typically: * **Material:** Tin-plated Brass or Phosphor Bronze. * **Usage:** Crimped onto wires to be inserted into a plastic housing for a secure electronic connection.
