SCHURTER LFM Indicator with SMD T1-3/4 LED

Category: Electronics, Optoelectronics, Schurter Inc

The datasheet presents technical specifications for the SCHURTER LFM Indicator with an SMD T1-3/4 LED. This indicator is designed for front panel mounting and comes in various models differentiated by the inclusion of a built-in resistor. The document provides details about dimensions, electrical data, material composition, resistance to soldering heat, ambient and storage temperatures, and degree of protection. It is evident that two distinct versions are available, one with and another without a built-in resistor.

Dimensions

Measurements for models with built-in resistors have a maximum width of 32mm and a height of 5mm to 9mm. Those without a resistor show a slightly different profile, featuring maximum widths of 19.5mm and a choice of two heights, either 5mm or 6.5mm. An internal reflector is also noted with maximum dimensions, but the exact values are omitted from the provided excerpt.

Electrical Data

The electrical specifications cite a current input technical data LED, but the specific values are referred to on page 91, which is beyond the scope of the provided content.

Solderability and Resistance

Both versions show resilience against soldering heat. Indicators with built-in resistors can withstand 235°C for a maximum of 5 seconds, according to IEC 68 2-20 Test Ta Method. Other types are capable of enduring a higher threshold of 350°C, based on the same testing criteria. In terms of temperature tolerances, the operating ambient temperature ranges from -25°C to +55°C, and storage temperature is specified from -55°C to +100°C.

Protection and Materials

The indicators are rated for a degree of protection marked at IP 40, signifying that they are protected against solid objects greater than 1mm but not against liquids. The material composition includes a brass chromium-plated body, copper-tinned solder, brass nickel-plated terminals, and implies the use of a nut in the assembly, although the material for the nut is not specified.
