SD

Product catalog summary

Specifications
The document outlines the specifications for the SD Series Low Profile DIP Switches. These switches are available in SPST configurations with 2 to 12 positions. The contact rating for carrying is 100 mA at 50 V DC max, and for switching, it ranges from 0.1 mA at 5 V DC min to 100 mA at 25 V DC max. The mechanical and electrical life is rated at 2,000 cycles at full load per circuit. Contact resistance is below 50 milliohms initially, insulation resistance is at least 109 ohms, and dielectric strength is 500 V RMS at sea level between adjacent terminals. The operating and storage temperature range is -40°C to 85°C, with an operating force of 100-700g initially.

Materials
The switches are made with a polyester (PBT) case and cover for thru-hole models and PPA for surface mount models, both flame retardant. The actuator is made of nylon, also flame retardant. Contacts are BeCu with gold plating, and terminals are bright tin-plated brass. All terminals are insert molded, and a polyimide tape seal is used.

Features/Benefits
The SD Series features a low-profile design, available in both thru-hole and surface mount models, with tape and reel packaging options. They are sealed with top tape and are RoHS compliant.

Applications
These switches are typically used for address switching in industrial controls, logic switching for computers and peripherals, and function controlling in various applications.

Ordering Information
Part numbers for the SD Series are detailed, with options for actuator type, terminal type, contact material, process seal, and packaging. The document provides a detailed chart for dimensions and quantities per tube or reel for different configurations.

Packaging and Dimensions
The document includes detailed dimensions for the switches, with diagrams showing the layout and measurements in inches and millimeters. Tape and reel packaging is available for surface mount options, with specific dimensions for pocket length, tape width, pocket depth, sprocket hole spacing, and pitch between pockets.
