Terminal Blocks > Screwless DIN-Rail Terminal Blocks
DINnector Screwless Terminal Blocks
DINnector DN series screwless terminal blocks use a spring clamping system to facilitate clean and efficient connections between electronic components and control/field wiring. These DIN-rail mounted modular blocks, in a range of wire size options, can be mixed according to specific needs; available in feed-through, common-point, grounding, disconnect and plug-in types.
Screwless DIN-Rail Terminal Blocks
Screwless DIN-Rail Terminal Blocks
DINnectors™ (DIN Rail Terminal Blocks)
- Faster installation than standard screws
- Easy clamp-system connection
- Maintenance free
- Meets UL, CSA and IEC standards
Jumper system design improvements have been made to the Screwless series of terminal blocks to add to the quality and reliability of the products.
- Screwless jumpers and associated terminal blocks are being discontinued and replaced with the redesigned -A series.
- The new products are identical in width and height and have the same sizes as the original line, with the only change being the design of the jumper system.
- The new -A series is designed to work in current and future applications.
Screwless terminal blocks save time and money. They offer a quick and easy clamping system that is secure and maintenance free. Just push the spring clamp, insert the wire and release.
DIN
Screwless Feed-Through DINnectors
Single level (feed-through) terminal blocks provide the means to connect two wires together, and are available in sizes suitable for up to 8 AWG wire.
Screwless Double-level DINnectors
Double-level terminal blocks offer twice the wiring density of feed-through blocks. Versions with internal jumpers, LEDs and diodes are available.
Screwless Common Point DINnectors
The two-to-two version allows multiple wires to be connected together by way of multiple spring-clamps. LED and diode variations are also available in this style.
Screwless Ground DINnectors
Ground terminal blocks are used to mechanically and electrically ground wires to the DIN rail to function as a ground bus bar. Ground blocks are green / yellow per international standards.
Screwless Disconnect DINnectors
The DN-QKBD12 disconnect terminal block allows fast circuit disconnection without rewiring by means of a pivoting, insulated “knife-blade.”
Screwless Plug-In DINnectors
Single and double level DN-QEMXxx screwless plug-in terminal blocks with spring terminals accept all DN-xxPLUG Euro plugs.
Screwless Terminal Block Accessories (Marking Tags & Tools)

- indelible marking pen
- Screwdrivers, wire cutter/stripper tools
- DIN-rail, DIN rail brackets
- Terminal block end covers
- Terminal block jumper bars
Why go screwless?
- Speed: On average, screwless connections can be made in half the time as screw type connections, cutting installation labor costs in half.
- Ease: No need for twisting and turning screws, so screwless terminal blocks are much easier on the installer's hands and arms. Also, wiring from the top of the terminal blocks allow installers to accurately and reliably see the wire fully inserted into the spring clamp.
- Safety: Never have a problem with loose connections from loose screws again! Meets the same UL, CSA, and IEC standards as screw-type terminal blocks.
- Reliability: Screwless terminal blocks provide secure connections.
- Maintenance-free: The screwless springclamp conforms to the wire with constant tension, making it maintenance-free.
Are there any trade-offs?
- Unless you need to clamp multiple wires to the same
connection point, the answer is no. If you do, then there may be
a slight trade-off in requiring more panel space than with screw
terminal blocks.
- Unlike screw terminal blocks, screwless terminal block spring-clamps are designed to clamp a single wire only.
- This is why multiple versions exist like the "one-to-two" or "two-to-two." These versions allow multiple wires to be connected together via multiple spring-clamps.
