It appears you are referring to the **201848**, which is a specific part number typically associated with **TE Connectivity (formerly Tyco Electronics)**. This part is a standard interface component used extensively in industrial and commercial electronic assemblies. --- ## 1. Part Overview: TE Connectivity 201848 The part number **201848-1** (and its variants) refers to a **Rectangular Connector Block** from the M Series. These are heavy-duty, multi-position connectors designed for high-reliability applications. ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Product Type** | Connector Housing / Block | | **Series** | M Series (Standard) | | **Number of Positions** | 34 Positions | | **Contact Gender** | Socket (Female) | | **Material** | Diallyl Phthalate (DAP) or Phenolic | | **Mounting Type** | Panel Mount / Free Hanging | | **Pitch/Spacing** | 3.81 mm [0.15 in] | --- ## 2. Key Characteristics These electronic parts are known for their durability in harsh environments. ### A. Material Properties The housing is usually made of **Diallyl Phthalate (DAP)**. This plastic is chosen for: * High heat resistance. * Excellent electrical insulation. * Dimensional stability (it doesn't shrink or warp over time). ### B. M Series Compatibility The 201848 block is a "housing only." To make it functional, it requires: 1. **Contacts:** Crimp-style pins or sockets (e.g., Type II or Type III+ contacts). 2. **Hardware:** Guide pins, sockets, or strain reliefs to secure the connection. --- ## 3. Common Applications Because of its 34-position density and rugged build, this part is commonly found in: * **Industrial Control Panels:** Linking sensors and actuators to a central PLC. * **Telecommunications:** Used in older rack-mounted switching equipment. * **Aerospace & Defense:** Ground support equipment where vibration resistance is necessary. * **Test Equipment:** Interface modules for automated testing stations. --- ## 4. Assembly Example If you were to integrate this into a project, your bill of materials (BOM) would look like this: ```markdown 1. Housing: Part #201848-1 (34-Position Block) 2. Contacts: Part #66105-4 (Crimp Sockets, 24-20 AWG) 3. Hardware: Part #200542-1 (Male Screw Retainer) ``` ---
