Based on the component designation **R10-R1W1AC**, this typically refers to a specific configuration of a **general-purpose industrial relay**, most notably produced by manufacturers like **Potter & Brumfield (TE Connectivity)**. Here is a breakdown of the electronic specifications and parts associated with this model: ### 1. Component Breakdown (Nomenclature) The alphanumeric code identifies the physical and electrical characteristics of the relay: | Segment | Meaning | Specification | | :--- | :--- | :--- | | **R10** | Series Type | Cradle-style, multi-contact industrial relay. | | **E1** | Enclosure | (Variations exist) Usually denotes a dust cover or specific case. | | **W** | Contact Type | Silver-cadmium oxide contacts (usually 2A - 5A rating). | | **1** | Contact Arrangement | Single Pole, Double Throw (SPDT / 1 Form C). | | **AC** | Coil Voltage | Designed for Alternating Current (Voltage depends on suffix, e.g., 24VAC or 120VAC). | --- ### 2. Internal Electronic Parts The relay consists of three primary sub-assemblies: #### A. The Coil Assembly * **Winding:** A fine copper wire coil that generates an electromagnetic field when AC voltage is applied. * **Core:** A soft iron core that concentrates the magnetic flux. * **Shading Ring:** Since this is an **AC** model, it includes a small copper "shading" ring on the pole piece to prevent "chatter" (vibration) caused by the 50/60Hz cycling of the AC current. #### B. The Contact System * **Moving Armature:** A hinged metal piece that is pulled toward the coil when energized. * **Springs:** Return springs ensure the contacts return to their "Normally Closed" (NC) position when power is removed. * **Contact Points:** Made of **Silver-Cadmium Oxide**. This material is chosen for its balance between conductivity and resistance to "arc welding" (sticking) under load. #### C. The Header and Terminals * **Solder/Plug-in Pins:** The R10 series is famous for its "cradle" pins, which can be soldered directly to a PCB or plugged into a dedicated socket (like the R10-S series sockets). --- ### 3. Technical Specifications (Typical) | Parameter | Value | | :--- | :--- | | **Contact Rating** | 2 Amperes to 7.5 Amperes (depending on specific W-rating) | | **Expected Life** | 100,000 operations (Electrical); 10,000,000 (Mechanical) | | **Dielectric Strength** | 500V to 1000V RMS between open contacts | | **Mounting** | Socket or PC Board | --- ### 4. Common Applications * **Logic Control:** Used in older industrial panels for interlocking circuits. * **Signal Switching:** Because of the R10's reliability, it is often used to switch low-power signals in telecommunications. * **Industrial Automation:** Interfacing between a low-power controller and a higher-power AC load.
