TE CONNECTIVITY 1546311-2

Quick Reference Guide Barrier Strips Barrier strip style terminal blocks from TE Connectivity are available in 3 main categories: dual-barrier, tri-barrier, and double row. Each category of barrier strip is offered in several industry standard centerline spacings, allowing you to choose from high density to high current applications. Dual-barriers and Tri-Barriers are very similar in that they are both offered with hardware which allows them to be used in either PCB or panel mount applications. Features & Benefits Product Applications • Available in centerline spacing from 0.250”- • Machine controls 0.4375” • Power supplies • Position sizes 2 to 30 • Test & measurement • Accepts wire range from 10-30 AWG dependant • Automation equipment on style • Security/alarm devices • Full line of accessories includes jumpers, quick • HVAC controls connect tabs, and some covers • Garage door openers • Binding head style and wire clamp screws are • Furnaces, water heaters, boilers available; binding head screws are typically used with hardware such as QC tabs and jumpers. • Wire screw clamps are best suited for bare wire applications. • Common contact styles offered in both dual- and tri-barriers: PCB pin, extended PCB pin, insulated ext.

Extra care has been taken to produce these components without burrs on any critical clamping surface or edges. Quality Plating TE has been known for its plating, especially on the tin- plated components, and has maintained stringent plating specifications to provide a better performing, more reliable product. Tri-Barrier Integral Standoffs Three walls or barriers surround each terminal screw. Standoffs help rid your PCB of any remaining corrosive The back wall safeguards field wiring. Image below: agents during rinsing operations. Helps prevent trapped solutions in the immediate PC pin area. Significantly reduces the risk of postwave corrosion problems. Gas-Tight Connections The acid-tin plating on your terminals means more than just improved shelf-life and superior solderability. It is to provide the very basis for the heart of your wire connections. Customization With the large number of hardware and contact options available, combined with various accessories, the barrier strip Double Row Barriers line can be customized for a wide variety of solutions for your Used in industrial controls and machine automation. Double PCB and panel mount applications. row barriers are used in panel mount and wire-to-wire applications.

Would you like to use accessories such as flat, 45 degree or TE offers barrier strips in both PCB and panel mount 90 degree quick connect tabs or jumper? configurations on the most common centerline spacings TE offers a wide range of accessories for each style of barrier ranging from 0.250"-0.4375". strip. Often times these accessories are pre-installed at our factory for your convenience. Is your application for control wiring or for higher current power connections? You may find these accessories at For control wiring, you may desire a higher density product www.te.com/products/barrierstrips such as # 3 Series Tri-Barrier or the 3DB dual-barrier. If you need a barrier strip UL up to 600 volts, then try looking at the Does your application require the block to have special SSB7 or #8 series products. mounting features? With the many styles of barriers available you will be able to find flat panel mounting versions as well as vertical and right angle through panel products.
