LFM Models with T1 LED – Technical Data and Dimensions

Category: Electronics, Optoelectronics, Schurter Inc

Overview

The datasheet provides technical specifications for LFM models equipped with 3mm T1 LEDs. The document includes dimensions for both internal and external models, electrical and other technical data, materials, and mounting information. A distinction is made between models with and without built-in resistors.

Dimensions

The datasheet outlines the dimensions for models with and without built-in resistors. Internal models with built-in resistors have a size of 22.8 x max. 25.3, while models without built-in resistors measure 2.5 x 65 x 13.8 (max. 6,3). External models with built-in resistors are indicated to be 3.6 x 21.7 x max. 25.3, and those without built-in resistors have dimensions stated as max. 36 x 65 x 12.7 (max. 16.3).

Technical Data

The technical data section is divided into three subsets: Electrical data, Other data which includes solderability, soldering heat resistance, ambient, and storage temperatures, degree of protection, and Materials which list the components used for the body, solder, terminals, and nut.

Electrical Data

For detailed electrical specifications, the datasheet refers to page 91, which might provide in-depth insights into current input and LED technical data like model numbers 0925.0029/30/67.

Other Data

Solderability is tested with the IEC 68 2-20 Test Ta Method where the maximum exposure time is 2 seconds at 235°C. Soldering heat resistance is evaluated with the IEC 68 2-20 Test Tb Method 1B, withstanding up to 5 seconds at 350°C. The ambient working temperature for the models varies between -25°C and +55°C, while storage temperature ranges from -55°C to +100°C. The degree of protection provided by the enclosure is IP 40.

Materials

The body of the LFM models is made of brass with a chromium-plating, the solder is GEAcSt, the terminals are copper tinned, and the nut is made of brass and nickel-plated. These materials indicate a robust construction suitable for reliable electronic applications.

Mounting and Contact Information

Front panel mounting with solder terminals is specified as the mounting type. Contact details, including a phone number, fax, email address, and website, are provided for further inquiries or support regarding the LFM models with T1 LEDs.
