The **WSBS-16AB-R/E** is a high-performance **Magnetic Reed Switch** sensor assembly typically manufactured by companies like Littelfuse (Hamlin). This specific part is designed for robust position sensing in industrial and commercial environments. --- ### ## Technical Specifications Below is a breakdown of the key electronic and physical characteristics: | Property | Description | | :--- | :--- | | **Contact Form** | Form A (Normally Open - SPST) | | **Contact Rating** | 10 Watts (Maximum) | | **Switching Voltage** | 200 Vdc (Maximum) | | **Switching Current** | 0.5 Amps (Maximum) | | **Operating Temperature** | -40°C to +105°C | | **Termination** | Wire Leads (typically with a specific connector/housing) | --- ### ### Core Electronic Components #### 1. The Reed Switch The heart of the device is a hermetically sealed glass envelope containing two ferromagnetic blades. - **Operation:** When a magnetic field (from a permanent magnet or electromagnet) comes into proximity, the blades are magnetized and pull together, closing the circuit. - **Durability:** Because the contacts are sealed in an inert gas, they are protected against oxidation and corrosion. #### 2. Encapsulation & Housing The "WSBS" series features a **threaded barrel housing**. - **Material:** Usually high-grade plastic or stainless steel. - **Protection:** The internal reed switch is "potted" with epoxy resin. This provides high resistance to vibration, shock, and moisture (IP67 rated in many configurations). #### 3. Lead Wires (R/E Suffix) The **R/E** suffix often denotes specific configurations regarding the exit of the wire or the type of connector used at the end of the leads. - **R:** Often indicates a specific resistance or a "Right-angle" exit depending on the manufacturer's specific catalog variation. - **E:** Usually refers to an extended wire length or environmental sealing enhancements. --- ### ### Key Features & Applications - **No Power Required:** As a passive component, it does not require a standby power supply to operate. - **Non-Contact Sensing:** Operates through non-ferrous materials (plastic, wood, aluminum). - **Common Uses:** - Door and window security sensors. - Limit switching in industrial automation. - Water flow meters and tank level sensing. - Automotive pedal or gear position sensing. ---
