NI 765530-01 Terminal Block

The NI 765530-01 Terminal Block is a 37-pin interconnect accessory that bridges National Instruments data acquisition systems to external sensors and instrumentation. It combines a 37-pin female spring terminal front end with a 37-pin female D-Sub rear connector, enabling tool-less wire termination on the signal side while maintaining industry-standard D-Sub connectivity for DAQ integration. The spring terminal mechanism automatically clamps incoming wires without requiring manual fastening, streamlining setup and reducing connection failures in field deployments.

– Technical Specifications

• Connector Type (Front): 37-pin female spring terminals
• Connector Type (Rear): 37-pin female D-Sub
• Maximum Peak Voltage: 42.4 V
• Maximum Current: 2 A
• Pin Count: 37

– Key Features

• Tool-less spring terminal connections eliminate screw fastening on the front end
• Automatic wire clamping mechanism ensures repeatable contact pressure
• D-Sub rear interface provides secure mating with standard NI DAQ connectors
• Dual termination approach accommodates both spring and D-Sub wiring paradigms
• Voltage and current ratings support low-voltage analog and digital signal routing

– Typical Applications

• Multi-channel analog input/output signal conditioning
• Sensor interface termination for temperature, pressure, and strain measurement
• Distributed I/O expansion in modular DAQ architectures
• Laboratory test benches requiring frequent sensor reconfiguration

– Compatibility & Integration

The NI 765530-01 is designed for National Instruments DAQ systems requiring a 37-pin D-Sub interface with parallel spring terminal access. Its dual connector architecture makes it suitable for legacy and current NI hardware platforms that standardize on this form factor.
