Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/POLOLU-2498:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description These side-entry terminal blocks have terminals that hold and release wires through the simple adjustment of a small screw, allowing you to easily make temporary connections to a PCB. Since each terminal has a single corresponding pin spaced every 0.1" (2.54 mm), these terminal blocks can be used with [prototyping boards](https://core-electronics.com.au/prototyping/proto-boards.html) and PCB holes intended for standard 0.1" [male](https://core-electronics.com.au/connectors-sockets/headers.html) and [female headers](https://core-electronics.com.au/connectors-sockets/headers/female-straight.html) (if there is sufficient clearance from nearby components). | [![](https://core-electronics.com.au/attachments/localcontent/0J6551_33528982c0e.jpg)](https://core-electronics.com.au/attachments/localcontent/0J6551_2159531bcd2.jpg) | |---| | 0.1" terminal blocks and a male header strip in an Adafruit Perma-Proto prototyping PCB. | | \| [![](https://core-electronics.com.au/attachments/localcontent/0J6525_2019131d163.jpg)](https://core-electronics.com.au/attachments/localcontent/0J6525_49663ef7e99.jpg) \| \|---\| \| 0.1" screw terminal block being used with a VNH5019 motor driver carrier in place of the included 0.1"-pitch male header. \| | \| [![](https://core-electronics.com.au/attachments/localcontent/0J6549_29605b55ef9.jpg)](https://core-electronics.com.au/attachments/localcontent/0J6549_766889aa33a.jpg) \| \|---\|---\| \| Using a 4-pin 0.1" screw terminal block for the motor and motor power connections on the #2136 DRV8801 dual motor driver carrier. \| | |---| Nine sizes are available, from 2 terminals through 10 terminals. | [![](https://core-electronics.com.au/attachments/localcontent/0J6530_469125ae9cb.jpg)](https://core-electronics.com.au/attachments/localcontent/0J6530_1874562529e.jpg) | |---| **Note:** These terminal blocks do not slide together like Pololu's [stackable screw terminal blocks](https://core-electronics.com.au/category/176/stackable-screw-terminal-blocks), and they do not fit next to each other on a 0.1" grid, so you will need to get the exact size required for application. Additionally, they do not work well in [solderless breadboards](https://core-electronics.com.au/prototyping/breadboards.html) (their pins are too short). **Dimensions** The following dimension diagram is for an N-pin version of this screw terminal block: | [![](https://core-electronics.com.au/attachments/localcontent/0J6529_571766da86b.jpg)](https://core-electronics.com.au/attachments/localcontent/0J6529_109208cb12a.png) | |---| | Screw terminal block: 0.1" pitch, side entry. | **Specifications** - Voltage rating: 150 V - Current rating: 6 A - Contact resistance: 20 mO - Wire gauge: 26-18 AWG - Wire strip length: 4.5 mm **Other terminal block options** Pololu carries several different sizes and styles of terminal blocks in addition to these 0.1" screw terminal blocks; the picture below shows a side-by-side comparison: | [![](https://core-electronics.com.au/attachments/localcontent/0J6547_52597f18efb.jpg)](https://core-electronics.com.au/attachments/localcontent/0J6547_173484d3323.jpg) | |---| | Side-by-side comparison of Pololu's different terminal blocks with a 0.1" male header strip for size reference.
