Datasheet
## **DYNAMIC SPRING CLAMP SERIES** TE Connectivity (TE)’s Dynamic spring clamp series of connectors provide efficient and reliable solution to power and signal line interface, especially for servo drive application. Their spring clamp design allows users to easily obtain a highly reliable wire termination, without having to use screw fasteners or crimps. The Dynamic spring clamp series adopts the classic multiple contact points of Dynamic family, all gold-plated, providing reliable and safe connection in harsh industrial environment. Vibration- and shock-proof, the push-on locking system with audible sound helps to improve efficiency and provide for long service life. The series is available in 3.5mm(D1900), 5.08mm(D2950), 7.5mm(D3950 and D4950) center line blocks for max. AWG 10/2.5mm2, handle up to 22A, – all conforming to the UL1059 standard for terminal blocks. ## BENEFITS - Highly reliable connection by “multiple contact points” stable contact performance. - • Safety and easy mating via locking system and guide rail - - Complete product portfolio for platform design ## APPLICATIONS - Servo Drive - PLC - Variable Frequency Controller - Robotic and CNC Control INDUSTRIAL /// DYNAMIC SPRING CLAMP SERIES **Dynamic Spring Clamp Series** ## KEY FEATURES ## **Spring Clamp concept** Spring clamp contact provides easy and high reliable wire termination. - Reduce processing time - Only inserting stripped wire into connector. - No screw fastening or crimping process required. - High reliability - Stable clamping force with Spring feature. - Avoiding operational dispersion in screw fastening process. ## **Push-on lock** Safety and easy mating by locking system. Just push the plug for mating of connector and proper position is confirmed with clear sound. **==> picture [224 x 140] intentionally omitted <==** **----- Start of picture text -----**<br> Spring<br>Wire<br>Housing lock<br>Contact Clamping force<br>Spring<br>Clamp contact<br>D3950 3POS Receptacle<br>**----- End of picture text -----**<br> ## PRODUCT SPECIFICATIONS |**Series**<br>||**D1900**<br>|<br>||**D2950**<br>|<br>||**D3950**<br>|<br>||**D4950**<br>|| |---|---|---|---|---| |Products image<br>~~a~~|~~ee~~|||| |Contact pitch [mm]<br>~~a~~<br>~~a~~|3.5<br>~~ee~~<br>~~ee~~|5.08<br>~~ee~~|7.5<br>~~ee~~|7.5| |Rated current max.<br>UL [A]<br>~~a~~<br>~~a~~<br>~~as~~|4 (AWG18 x 1)<br>~~ee~~<br>~~ee~~<br>~~ee~~|11.5 (AWG14 x 5)<br>~~ee~~<br>~~ee~~|14.5 (AWG14 x 1)<br>~~ee~~<br>~~eee~~|22 (AWG10 x 8)<br>~~eee~~| |Rated current max.<br>IEC [A]<br>~~a~~<br>~~as~~<br>~~a~~|-<br>~~ee~~<br>~~ee~~<br>~~ee~~|-<br>~~ee~~<br>~~ee~~<br>~~ee~~|-<br>~~ee~~<br>~~eee~~<br>~~ee~~|~~eee~~<br>~~ee~~| |Rated voltage<br>UL1059 B [V]<br>~~as~~<br>~~a~~<br>~~a~~|150 AC/DC<br>~~ee~~<br>~~ee~~<br>~~ee~~|300 AC/DC<br>~~ee~~<br>~~ee~~<br>~~ee~~|300 AC/DC<br>~~eee~~<br>~~ee~~<br>~~ee~~|300 AC/DC<br>~~eee~~<br>~~ee~~| |Rated voltage<br>UL1059 C [V]<br>~~a~~<br>~~a~~<br>~~a~~|-<br>~~ee~~<br>~~ee~~<br>~~ee~~|-<br>~~ee~~<br>~~ee~~<br>~~ee~~|300 AC/DC<br>~~ee~~<br>~~ee~~<br>~~ee~~|300 AC/DC<br>~~ee~~<br>~~ee~~| |Rated voltage<br>UL1059 D [V]<br>~~a~~<br>~~a~~<br>~~ee~~|-<br>~~ee~~<br>~~ee~~<br>~~ee~~|300 AC/DC<br>~~ee~~<br>~~ee~~<br>~~eee~~|600 AC/DC<br>~~ee~~<br>~~ee~~<br>~~eee~~|600 AC/DC<br>~~ee~~<br>~~ee~~| |Rated voltage IEC<br>Pollution<br>Degree: 3, Protection<br>Class: III [V]<br>~~a~~<br>~~ee~~<br>~~a~~|-<br>~~ee~~<br>~~ee~~<br>~~ee~~|-<br>~~ee~~<br>~~eee~~<br>~~ee~~|-<br>~~ee~~<br>~~eee~~|400 AC/DC<br>~~ee~~<br>~~ee~~| |Dielectric withstand-<br>ing Voltage :<br>~~ee~~<br>~~a~~|1,100V AC<br>~~ee ~~<br>~~ee~~|2,200V AC<br> ~~eee~~<br>~~ee~~|2,200V AC<br>~~eee~~|2,200V AC<br>~~ee~~| |Wire size [AWG]<br>~~a~~<br>~~a~~|24 - 18<br>~~ee~~<br>~~ee~~|22-14<br>~~ee~~|22-14|16-10| |Wire size [sq]<br>~~a~~<br>~~a~~|0.2-0.75<br>~~ee~~<br>~~ae~~|0.3-2.0<br>~~ee ee~~|0.3-2.0<br>~~ee~~|1.25-5.5<br>~~ee~~| |Product specifica-<br>tion :<br>~~a~~<br>~~a~~<br>~~a~~|108-78336<br>~~ee~~<br>~~ae~~<br>~~ee~~|108-140221<br>~~ee ee~~<br>~~es~~|108-78997<br>~~ee~~|108-140216<br>~~ee~~| |Instruction sheet:<br>~~a ~~<br>~~a~~|411-78291<br> ~~ae~~<br>~~ee~~|408-78172<br>~~ee ee~~<br>~~es~~|411-78272<br>~~ee ~~|408-78173<br> ~~ee~~| |Ferrules size [sq] or<br>[AWG]<br>* Please contact to<br>sales team for detail<br>~~a~~<br>~~a~~|-<br>~~ee~~<br>~~ee~~|0.75sq<br>~~es~~<br>~~ee~~|AWG14~AWG16<br>~~ee~~|AWG16~AWG12| |Pos #<br>~~a~~|8, 12, 16, 22, 30, 38pos<br>~~ee~~|5pos, 6pos<br>~~ee~~|3,4,6,8,11pos<br>~~ee~~|8pos| INDUSTRIAL /// DYNAMIC SPRING CLAMP SERIES **Dynamic Spring Clamp Series** DYNAMIC SPRING CLAMP D1900 SERIES.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
