Barrier terminal blocks.

The DKU series of screw type barrier terminal blocks, from Dinkle International, are typically used for power transmission in control panels and power distribution cabinets, and they have been upgraded for easier use with various types of cable lugs. They are particularly suitable for high vibration industrial applications, including transportation and railway.

Traditional designs for screw terminals required workers to entirely remove screws and washers when connecting ring-lugged wires, which is time-consuming and can lead to dropped and lost screws.

New DKU screw type terminal blocks use a spring-guided system where the screws are integrated and captive within the terminal enclosure. These screws can be backed out so that ring- or U-shaped cable lugs can be inserted, without the possibility of losing the screw. The housing also ensures proper alignment of the screw and lug. Connection screws are integrated with washers to deliver secure connectivity and vibration resistance, even in harsh environments. The screws and washers are made with zinc-plated steel to inhibit rust.

The DKU terminal housing is designed to enclose the screws and conductors, providing better protection for the user and equipment than traditional designs that lack a cover. DKU terminals are available in DIN rail and panel-mount configurations, and are offered with accessories to improve installation convenience, such as jumpers, marking labels, end caps, and end brackets.

DKU terminals are offered in five sizes ranging from 15A for M3 and 26-14AWG, up to 60A M5 20-6AWG, all rated for use up to 600V. They carry approvals from UL and cUL recognized, and and the materials are RoHS compliant.

Plug-In Easy-Test Terminal Blocks.

New disconnect terminal blocks implement plug-in technology, safe design, and space savings with testing capabilities for use in CT and VT secondary circuits.

Dinkle International has announced the availability of its DPT DIN rail disconnect terminal blocks to provide efficient, safe disconnect and testing of current transformer (CT) and voltage transformer (VT) circuits.

CTs and VTs isolate a primary power feed from a secondary circuit, permit grounding of the secondary circuit, and step-down the current or voltage to an appropriate level for measurement. Terminal blocks are then used as the termination points for instrument loops on the secondary circuit.

Panel builders have traditionally incorporated barrier-type terminal blocks in CT circuits—but these are challenging to access, require proper tools, and take time for backplane mounting and screw-down wire terminations. Additionally, there is always the danger of under-torqueing and loose wiring connections, or over-torqueing and stripped screw threads.

Dinkle’s DPT DIN rail series terminal blocks address these issues by providing easier access, DIN rail mounting with no tools required, and push-in design to ensure secure wiring connection while reducing time and tools required for termination.

The DPTD6 model block also provides direct-testing technology, enabling a user to test the circuit current without undoing any wired connections. To perform direct-test for a single or three-phase circuit, the user switches a lever on the terminal block to disconnect a de-energized circuit. The user then places a current-measuring device across the block at its test points using either 4mm test probes or securely fastened 2.3mm test plugs. The DPTL6 model version is similar to the DPTD6 but without a disconnect lever for testing.

Both blocks are UL rated up to 30 amps at 600 VAC. The blocks are DIN rail mountable and measure 8mm in width by 103.2mm in height by 50-57.5mm in depth (depending on DIN rail depth), allowing for easier installation and space saving compared with traditional barrier-type terminal blocks.

These push-in style blocks accommodate wire sizes from AWG20 to AWG8, and also feature plug-in slots for bridges (jumpers), providing reliable continuity between any combination of blocks on the same DIN rail. They are completely touch-safe—back of hand and finger protection—and operate at temperatures from -40°C (-40°F) to 120°C (248°F).

Users can employ these DPT series blocks to safely disconnect secondary circuits between measuring instruments and safety equipment in CT shorting and other applications. A safe disconnect can be achieved by placing the block in front of the measurement instrument.

Pluggable Terminal Blocks.

Dinkle International's pluggable terminal blocks are a series of products with a unique push-in-design for connecting wires to the terminal blocks.

A pluggable terminal block is composed of a plug and a mating socket. The socket is usually attached to a printed circuit board through pins. The plug fits into the socket, and the wires connect to the socket via their patented push-in-design. This design improves upon traditional screw terminals in terms of efficiency, ease of use and space savings.

Screw terminals take time to tighten properly, and there is always the danger of under torqueing and loose connections, or over torqueing and stripped screw threads. By contrast, wires connected using Dinkle’s push-in-design technology assure a secure connection, with about 75% less time required per wire installation.

Connecting a solid wire with push-in-design takes only 3.6 seconds, compared to 13.5 seconds for a screw connection. A flexible wire takes just 4.1 seconds to connect, while a screw terminal takes 14.4 seconds. A flexible wired with a ferrule takes only 3.7 seconds to connect, compared to 13.2 seconds for a screw terminal.

Pluggable terminal blocks are available in a wide variety of sizes and ratings. Pitch varies from 2.54-6.35 mm, with wire ranges from 30-16 to 24-12 AWG. Current ratings are 5-8 amps at 150 Vac, 8-16 amps at 300 Vac, and 20 amps at 600 Vac. Connection methods are V-type spring (not patented), or patented S-Cage single, double and rail type. Value-added customization services include label printing, and supplying blocks in assorted color combinations.

An LED at each connection point is on when current is flowing through the wire, with LED light pipes integral to the terminal block assemblies used to ensure each LED is clearly visible. This indication provides quick visual confirmation of active connections and is very useful for troubleshooting.

Mini type pluggable terminal blocks include the 0225, 0226 and 0227 series. The 0225 series has an ultra-thin housing with a 7mm height, able to accommodate a broad cross section of 1.5 mm² wire. Various selections of mounting methods contribute to a vibration-proof, secure connection. These terminal blocks are well suited to installation within PLCs, I/O modules, signal panels, etc.

The series 150 pluggable terminal blocks are rated at 16 amps at 300 Vac and 20 amps at 600 Vac. These high-current terminal blocks are resistant to elevated levels of vibration, with a stopper mechanism to avoid overloading. An innovative smart clip facilitates quick plugging and unplugging. The terminal blocks have an ultra-mini housing with a height of 13.80mm. Typical application include motion control components such as servo and stepper drives and amplifiers.

The series 0181, 0156 and 0159 pluggable terminal blocks have a bi-level compact structure to provide space saving and cost effectiveness. The 0156 and 0159 series provide for different printed circuit board layouts to fulfill various market demands and applications. Assorted options of plugging/unplugging methods are available including lock & release, smart clip and screw flange.
