## Overview: 1375-R6BK Electronic Parts The **1375-R6BK** is a specific part number typically associated with **Schlegel** (a German manufacturer of high-quality control units) or similar industrial switch components. Specifically, it refers to a **Contact Block** used in pushbuttons, emergency stops, and selector switches. --- ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Component Type** | Contact Block | | **Contact Configuration** | 1 NC (Normally Closed) + 1 NO (Normally Open) | | **Termination Type** | Faston terminals (typically 2.8 x 0.8 mm) | | **Illumination** | Non-illuminated (standard for R6BK series) | | **Contact Material** | Silver-Nickel (AgNi) or Gold-plated options | | **Rated Current** | 6A (at 250V AC) | | **Degree of Protection** | IP00 (requires housing for higher ratings) | --- ### Key Electronic Components The 1375-R6BK is an electromechanical device. Its functionality relies on several internal physical parts: #### 1. Contact Elements * **NC (Normally Closed):** The circuit is complete when the button is at rest. Activating the switch breaks the circuit. * **NO (Normally Open):** The circuit is broken at rest. Activating the switch completes the circuit. * **Snap-Action Mechanism:** Ensures a rapid transition between states to prevent "arcing" (sparks) that can degrade the metal contacts. #### 2. Terminals * These are the metal prongs protruding from the back of the block. * They are usually designed for **Faston plug-in connectors**, allowing for quick assembly without soldering in industrial control panels. #### 3. Plunger/Actuator Interface * The mechanical interface that receives the physical force from the button head. When pushed, it moves the internal spring-loaded bridge to swap contact positions. --- ### Applications These blocks are modular and are typically found in: * **Industrial Control Panels:** To start or stop machinery. * **Safety Interlocks:** Using the NC contact for emergency stop functions. * **Automation Systems:** Providing feedback signals to PLCs (Programmable Logic Controllers). --- ### Compatibility Note The "R6BK" suffix often denotes the specific series compatibility (such as the **RONDEX** or **QUARTEX** series by Schlegel). Always ensure the mounting diameter (usually 22.3mm or 16.2mm) of the button head matches the contact block type.
