Standard Screw DIN-Rail Terminal Blocks (Listed by Block Type)

DINnectors (DIN Rail Terminal Blocks)

Most control panels use some sort of terminal strips or terminal blocks to connect the control wiring (PLCs, relays, contactors, etc.) to the field wiring. DINnectors are simply DIN rail-mounted connectors or terminal blocks. They provide a means of connecting and identifying two or more wires within the demands of an industrial environment. The DIN-rail is the internationally approved, industry standard mounting rail for components made by hundreds of manufacturers worldwide.

Many thanks to our customers who have made the switch to our DINnector terminal blocks!
They’ve told us DINnectors are the same or better quality than the brand they were using, but are significantly less expensive. From skateboard manufacturing to precision machine tools, from panel shops to petrochemical plants, customers love the low price and value that our direct/ e-commerce sales channel offers.

DINnectors can terminate solid or stranded wires ranging from 18-3/0 AWG, and offer fusing, grounding or disconnecting capability within the terminal block itself. Our range of DINnectors terminal blocks is internationally approved by various national and international standards organizations such as UL, CSA, VDE, SEV, RINA and IEC. Choose from the seven types of terminal blocks as required for your system: feed-through, multi-level, mini, ground, fuse, disconnect or direct mount.

Here are five reasons to try our DINnector terminal blocks:

• Quality materials
• Self-locking clamps
• High-contact pressure
• Low voltage drop
• Gas-tight connections

Single-level Terminal Blocks and Accessories

DINnectors can terminate solid or stranded wires ranging from 18-3/0 AWG, and offer fusing, grounding or disconnecting capability within the terminal block itself. Feed-through terminal blocks are available in a number of colors and wire size options to ensure flexibility and ease of installation for your DIN-rail mounted conection system.

Double-Level Terminal Blocks and Accessories

Models include:

• Feed-through terminal blocks
  Double-level terminal blocks offer twice the wiring density of feed-through blocks. The DN-D10 is a straight feed-through block. The DN-D10X version is supplied with an internal jumper to common all four of its connection points. Standard models come in a variety of colors.
  
  
• LED terminal blocks
  These terminal blocks provide built-in LED indicators. The LED illuminates when voltage is present. The LED1 version is for 24 VAC/ VDC circuits, and includes current-limiting elements.
  
  
• Diode terminal blocks
  Typically, an inductive load produces a spike (neg.-going) when it is turned off. These terminal blocks with built-in clamping diodes help protect your PLC’s output circuits.

Triple-level Terminal Blocks and Accessories

Our triple-level terminal blocks enable either high-density wiring or simplified, low-cost sensor wiring. There are four types, with and without LED.
These terminal blocks offer an extremely compact 5 mm thick design.

• DN-TL14 - Connects three separate circuits in only 5 mm of linear DIN rail space
  
  
• DN-TL14S - Standard sensor terminal block, allows you to wire one terminal block per sensor, vs. the traditional method, which requires three different single-level blocks per sensor.
  
  
• DN-TL14SLP and DN-TL14SLN models provide LED indication at the terminal block when voltage is present.

Mini Terminal Blocks and Accessories

Mini terminal blocks are used in areas with extremely limited space requirements, and mount on the smaller DIN rail type DNR15S1.

Ground Terminal Blocks and Accessories

Ground terminal blocks are used to mechanically and electrically connect wires to the DIN rail by means of a conducting clamping foot. In this way, the DIN rail can function as a ground bus bar. Ground blocks are molded in green and yellow per international standards.

Fuse Terminal Blocks and Accessories

• DN-FM6 series
  These 600 V, 30 A DIN rail-mountable fuse blocks are available with a long lasting neon indicator light for quick troubleshooting. The permanently attached pivoting fuse door simplifies and speeds fuse replacement without using tools. The IP-20 rated fuse blocks also offer lockout/tagout compliance, via the lockable extraction door, to meet OSHA requirements. Midget fuses are supplemental fuses and are not rated for current limiting applications. They do not have rejection tips. They are white in color. Class CC fuses are current limiting fuses with rejection tips on the bottoms to prevent them from being used in holders not rated similarly.
  
  
• DN-F6 and DN-F10 series
  Fuse blocks are available for 1/4", 5 mm, and Class CC size fuses, either with or without a blown fuse LED. LED fuse blocks are polarity sensitive. The modular design allows additional poles to be added in the field using a pin-assembly kit.

Disconnect Terminal Blocks and Accessories

The DN-DIS10 and the DN-KBD12 allow fast circuit disconnection without rewiring.

• The DN-DIS10 is supplied with a copper disconnect bar installed in the fuse holder.
  
  
• The DN-KBD12 offers circuit disconnection capability by means of a pivoting, insulated “knife blade”.

Direct Mount Terminal Blocks and Accessories

Direct mount terminal blocks are a low cost alternative to modular terminal blocks. Direct mount terminal blocks do not require the use of a DIN-rail to mount. By utilizing two mounting screws, they can be mounted to any backplane. They are supplied with or without wire protectors and can easily be cut to length with ordinary hand tools. Wire protectors are metallic strips that physically isolate the conductor from the terminal screw. The wire protectors prevent softer conductors from getting cut or nicked.

ACCESSORIES

General Accessories

Terminal block accessories include:

• Rails
• End brackets
• End covers
• Angled support bracket
• Cover top
• Separators
• Jumpers
• Screwdriver
• Wire cutter/ stripper tool
• Marking tags and accessories
  (blank and printed tags, tag adapter, indelible marking pen, etc.)

Marking Tags and Accessories

Marking tags provide circuit organization and identification. DN-L Series tags are available either blank or preprinted from 1-1000 in 5 mm and 6 mm widths.
A wide variety of marking tags and accessories are available. Available items include:

• Marking tag adapter
  
  
• Indelible black ink marking pen
  
  
• Marking tag (DN-L) - Fits terminal block types: All except: DNT12(B), DN-M10(B), DN-MG and DN-TL series
  Material: Thermoplastic with heat embossed black print
  
  Notes:
  1. The DN-L tags fit all DINnectors 6 mm wide and wider.
  
  
• Marking tag (DN-LA Series) - Fits terminal block types: DN-T12 series
  Material: Thermoplastic with heat embossed black print
  
  Notes:
  1. The DN-T12 series is 5 mm wide, so the 6 mm wide DN-L tags do not fit these blocks.
  2. The DN-LA tags fit all DINnectors 5 mm wide and wider but will leave a gap between terminals on blocks wider than 5 mm.
