The EATON CS-TX3-3.81X2.54-64TW is a high-density 64-position terminal block from EATON’s Combicon TX3 series, designed for industrial signal distribution in harsh environments. This dual-row spring-cage connector features 3.81mm horizontal and 2.54mm vertical pitch spacing, enabling 35% higher wiring density than standard DIN rail terminals. The CS-TX3-3.81X2.54-64TW serves as critical infrastructure in PLC I/O racks, providing reliable signal routing between control systems and field devices.
Certified to UL 1059 and IEC 60947-7-1 standards, this terminal block supports wire ranges from 24-12 AWG (0.2-4mm²) with 750V AC isolation between adjacent contacts. The nickel-plated copper alloy construction ensures <1mΩ contact resistance even after 500 mating cycles. As part of EATON’s modular interconnection system, the EATON CS-TX3 series integrates seamlessly with Phoenix Contact and Weidmüller interface components.

Key Features and Advantages:
Space-optimized design: The EATON CS-TX3-3.81X2.54-64TW achieves 64 circuits in 97mm width through precision-stamped contacts. Its dual-level test points allow live circuit diagnostics without disconnection, reducing maintenance downtime by 40%.
Enhanced reliability: The captive spring mechanism maintains 20N residual contact force after 10,000 thermal cycles. Transparent end covers with integrated polarity markers prevent reverse wiring in multi-voltage systems.
Tool-less installation: Patented push-in technology enables single-handed wire insertion with 50% less effort compared to screw terminals. The integrated wire funnel guides stranded conductors into optimal contact position.
Application Areas:
The EATON CS-TX3-3.81X2.54-64TW excels in:
- Motor control centers: Multi-axis servo drive signal routing
- Process instrumentation: 4-20mA loop distribution
- Energy management: Power meter data aggregation
- Rail signaling: Axle counter interface modules
In pharmaceutical cleanrooms, this terminal block’s corrosion-resistant contacts withstand daily CIP (Clean-in-Place) chemical sprays. Its marine-grade variant (CS-TX3-M) features tin-plated contacts for salt fog environments per EN 60068-2-52.
