Dorabo DB125 and DB127 screw lifting terminal blocks

Dorabo PCB screw terminal blocks featuring rising elevator clamp mechanisms across DB125, DB127V, DB127S and DB128A series. The elevator clamp eliminates conductor twisting and strand breakage under torque, maintaining steady contact pressure in vibrating machinery.

Contact pitches of 2.54, 3.5, 5.0 and 5.08 mm for through-hole PCB soldering
Nickel-plated copper alloy lifting cage preventing conductor strand corrosion
Built-in test points on the insulator body for multimeter probe diagnostics

Dorabo DB301 and DB331 spring clamp terminal blocks

Dorabo push-in and tension spring terminal blocks of DB142R, DB142V, DB250A, DB301S and DB331K lines. The stainless steel spring cage compensates for thermal expansion and maintains contact force without requiring periodic screw retightening on automated lines.

Push-in direct insertion for solid wires and stranded conductors with ferrules
Actuation lever or push button enabling swift wire release without damage
Resilient performance under sustained machine vibration and thermal cycles
Compact housing volume saving valuable layout footprint inside control boxes

Dorabo DB14H feed-through blocks and energy connectors

Dorabo panel feed-through terminal boards of DB14H, DB16H, DB18H series, paired with high-current energy storage connectors and DA, DAC, DI DIP switches. Provide inter-module power feeds and reliable configuration switching across machine drive electronics and power cubicles.

Feed-through bulkhead mounting across panel walls with reinforced dielectric
Heavy-duty energy storage connection pairs engineered for battery cabinets
DIP switches featuring gold-plated contacts for hardware address programming
High dielectric breakdown protection withstanding test voltages up to 2500 V

Modular architecture of Dorabo DB2EK pluggable terminal blocks

Dorabo pluggable terminal blocks across DB2EK, DB2EVK and DB2EURKM product families employ a two-piece interconnection architecture uniting a wire-side plug with captive screw terminals and a board-mounted header.

This modular layout permits rapid wire harness disconnection during machine maintenance without loosening individual conductors.

Terminal contacts are fabricated from high-conductivity copper alloy with tin or gold plating to maintain low contact resistance. Insulating housings are molded from polyamide PA66 achieving UL94 V-0 flame retardancy.

Polarized keying slots prevent incorrect mating while integrated side locking flanges secure the connection against operational vibration.

Selection of Dorabo terminal blocks by rating and terminal pitch

Our engineering department provides selection of Dorabo electrical connectors based on machinery rating plate photos, housing markings, pin spacing dimensions or schematics.

Within the manufacturer catalog, core design parameters span contact pitch from 2.54 mm up to 15.0 mm, pole counts from 2 to 24 and terminal wire clamping principles.

To replace aging components from brands like Phoenix Contact, Weidmuller or Degson, we identify direct Dorabo functional equivalents matching footprint dimensions and electrical loading capacity.

This enables straightforward retrofits of industrial controllers, drive units and distribution panels without altering printed circuit layouts.

Assembly and service procedures for DBT barrier blocks in power units

Dorabo DBT series barrier terminal strips are engineered for wiring power circuits in electric motors, frequency converters and heavy uninterruptible power supplies.

Elevated barrier walls deliver air clearance and creepage distance between adjacent terminals, preventing flashover even within dusty industrial workshop atmospheres.

Terminal screws with captive lock washers provide consistent clamping pressure on ring and spade wire lugs, preventing screw loosening under sustained machine vibration.

Clear polycarbonate protective covers safeguard maintenance personnel against accidental live part contact and facilitate visual inspection during routine maintenance rounds.

Control cabinet layout using Dorabo DUV series DIN-rail terminals

The Dorabo DUV series of modular feed-through terminal blocks mounts onto standard 35 mm DIN rails, organizing signal and power wiring inside machine tool control cubicles.

Standard modules DUV1.5, DUV2.5, DUV4 and DUV6 incorporate dual cross-connection channels to accept comb jumpers for rapid potential and ground distribution.

The narrow housing profile optimizes space utilization inside enclosures, accommodating higher I/O channel density for programmable logic controllers.

Marking strips and end barrier plates protect assemblies against mechanical disturbance, while dedicated grounding blocks establish firm electrical contact with the mounting rail.

Push-in wire termination principles in Dorabo DB301 and DB331 series

Screwless spring terminal blocks of Dorabo DB301 and DB331 series featuring Push-in direct connection technology minimize electrical assembly labor.

Solid conductors or flexible stranded wires fitted with ferrules insert directly into the clamping chamber with light insertion effort, where a stainless steel spring clamp secures the wire core.

Continuous spring clamping force automatically compensates for copper settling and thermal fluctuation under electrical loads, eliminating routine screw retightening.

Integrated orange actuator push-buttons open the spring cage using a standard screwdriver, permitting wire removal without terminal distortion.
