1sna115291r1700 – m4/7,r
TE Connectivity M4/7.R 1SNA115291R1700 is a grey 4 mm² ENTRELEC SNA screw-clamp component holder terminal block with a 20 Ω ±10% variable resistor for compensating line resistance in industrial measurement circuits.
Why Choose the TE Connectivity M4/7.R Component Holder Terminal Block 1SNA115291R1700?
The TE Connectivity M4/7.R 1SNA115291R1700 is a specialised 4 mm² screw-clamp component holder terminal block from the ENTRELEC SNA range. Designed for measurement and instrumentation circuits, it incorporates a 20 Ω ±10% variable resistor that allows compensation for line resistance within the measurement circuit.
The M4/7.R combines this adjustable resistance function with proven screw-clamp connection technology. It accepts flexible and rigid conductors from 0.5–4 mm², while its compact 7 mm spacing helps conserve DIN rail space in control, instrumentation and measurement panels.
With a rated voltage of 750 V, a rated cross-section of 4 mm² and a short-time withstand current of 480 A for 1 s, the M4/7.R provides dependable electrical performance for specialised industrial circuits. Its grey polyamide housing, IP20 main-terminal protection and compatibility with G32, TH35-7.5 and TH35-15 DIN rails support flexible professional panel construction.

Reliable Line-Resistance Compensation for Measurement Circuits
Measurement circuits can be affected by resistance introduced by connecting conductors, particularly where accurate electrical measurements are required over extended wiring runs. The M4/7.R addresses this requirement by incorporating an adjustable 20 Ω ±10% resistor, enabling the circuit to be trimmed to compensate for line resistance.
Integrating the resistor directly into a DIN rail terminal block helps create a neat and serviceable installation without requiring a separate panel-mounted component. Combined with the ENTRELEC SNA screw-clamp platform, the M4/7.R provides a practical solution for instrumentation, monitoring and industrial measurement systems.
Typical Applications
- Industrial measurement circuits.
- Instrumentation and monitoring panels.
- Line-resistance compensation circuits.
- Industrial electrical control panels.
- Factory automation and process-control equipment.
- Machine building and OEM electrical systems.
- DIN rail assemblies requiring an integrated adjustable resistor.
