Based on the part number **PBSSF-S-R**, this is a specialized electronic component typically associated with **push-button switches**, often utilized in industrial controls or high-quality consumer electronics. Below is a breakdown of the electronic and mechanical characteristics of this series. --- ## 1. Component Identification The PBSSF series generally refers to **Stainless Steel Push Button Switches**. These are designed for durability, tactile feedback, and environmental resistance. | Feature | Specification Details | | :--- | :--- | | **Component Type** | Momentary or Latching Push Button Switch | | **Material** | Stainless Steel (Body and Actuator) | | **Mounting Type** | Panel Mount (Threaded) | | **Termination** | Solder Lug or Screw Terminal | | **RoHS Status** | Compliant (indicated by the `-R` suffix) | --- ## 2. Part Number Breakdown While specific manufacturers (like Langir or similar industrial brands) may vary slightly, the nomenclature typically follows this logic: * **PB**: Push Button. * **SS**: Stainless Steel (Housing material). * **F**: Flat Head (The shape of the button surface). * **S**: Short Body (Space-saving design for shallow panels). * **R**: RoHS Compliant (Environmentally friendly manufacturing). --- ## 3. Electrical Characteristics These parts are engineered to handle signal-level to moderate power-level switching. * **Contact Configuration:** Usually **1NO** (Normally Open) or **1NO1NC** (Normally Open/Normally Closed). * **Switch Rating:** Typically **2A 36VDC** or **3A 250VAC**, depending on the specific sub-model. * **Contact Resistance:** $\le 50m\Omega$. * **Insulation Resistance:** $\ge 1000M\Omega$. * **Dielectric Strength:** 2000VAC. --- ## 4. Physical & Environmental Specs The "SS" (Stainless Steel) designation is the most critical electronic/mechanical part of the specification, providing the following: ### Mechanical Properties * **Operating Force:** Approximately 3N to 5N. * **Operating Travel:** ~2.0mm. * **Mechanical Life:** > 1,000,000 cycles. ### Environmental Protection * **IP Rating:** Typically **IP65** or **IP67** (Dust-tight and protected against water immersion/jets). * **IK Rating:** **IK08** or **IK10** (Vandal resistant against high-impact energy). * **Operating Temperature:** $-20^\circ\text{C}$ to $+55^\circ\text{C}$. --- ## 5. Typical Applications Due to the stainless steel construction and robust electrical ratings, these parts are found in: 1. **Industrial Control Panels:** Machine start/stop functions. 2. **Public Kiosks:** Vandal-resistant interfaces (ATMs, elevators). 3. **Marine Equipment:** Resistance to salt spray and corrosion. 4. **Medical Devices:** Easy to clean and sterilize surfaces.
