The **SHSP-1-R** is a specific electronic component typically classified as a **High-Voltage Reed Sensor** or a **Magnetic Proximity Switch**, often manufactured by companies like Standex Electronics (Meder). Below is a detailed breakdown of its electronic characteristics and technical specifications. --- ### 1. Component Overview The SHSP-1-R is designed for non-contact sensing. It operates using a reed switch hermetically sealed inside a plastic housing, triggered by the presence of a magnetic field. | Feature | Description | | :--- | :--- | | **Type** | Magnetic Reed Sensor | | **Contact Form** | Form A (Normally Open) | | **Termination** | Wire Leads / Through-hole | | **Housing** | Rectangular Plastic Case | | **Switching Voltage** | High Voltage (Up to 1000V DC/AC) | --- ### 2. Key Electronic Specifications These devices are known for their high isolation and ability to handle significant voltage despite their small size. * **Switching Power:** Usually rated up to 100W. * **Switching Current:** Typically 1.0A to 3.0A. * **Breakdown Voltage:** High dielectric strength (often >2000V DC). * **Contact Resistance:** Very low (under 150mΩ) due to precious metal plating on the internal reeds. * **Operating Temperature:** -20°C to +85°C. --- ### 3. Internal Working Principle The "Electronic Part" consists of two ferromagnetic blades (reeds) inside a glass envelope. 1. **Magnet Interaction:** When a permanent magnet moves within the "Pull-In" range, the magnetic flux causes the reeds to attract and touch. 2. **Circuit Completion:** Once the reeds touch, the electrical circuit is closed. 3. **Release:** When the magnet is removed, the mechanical tension of the reeds causes them to snap back to the open position. --- ### 4. Typical Applications The SHSP-1-R is preferred in environments where environmental sealing is required or high voltages are present. * **Industrial Safety:** Door and cover interlocks on high-voltage machinery. * **Level Sensing:** Floating magnets in liquid tanks. * **Security:** High-reliability window and door sensors. * **Automation:** Limit switching in robotics. --- ### 5. Wiring Diagram (Logical) The SHSP-1-R is a passive device and does not require power to operate; it acts as a simple switch. ```text [ VCC / Load ] ----+---- [ SHSP-1-R ] ----+---- [ Ground / Circuit ] | (Switch) | | | (Open when Magnet is Far / Closed when Magnet is Near) ```
