Benit 2321132 Spiral Extension Cord Keeps Asphalt Paver Grade Sensors Working

Road construction crews know that a paving job is only as accurate as the signal feeding the screed control system. When the grade sensor cable on an asphalt paver becomes stretched, cracked or intermittent, the machine loses its reference and paving thickness drifts. Suzhou Benit Machinery Technology Co.,Ltd now keeps the Benit 2321132 1.5m spiral extension cord in regular stock, giving contractors a direct replacement option for S2100 and S2100-3 pavers without waiting for long lead times.

What the 2321132 cable does on the machine

The 2321132 is a coiled spiral cable that connects the grade sensor to the machine control unit on the electric system of the paver. It carries the sensor signal through an 8 pin 7 hole CAN connector that matches the original wiring layout, so it can be installed as a plug and play replacement. The 1.5m working length is matched to the travel of the sensor arm, and the coiled body retracts when the arm comes back so the cord never hangs loose over the hot mat.

Why the spiral design matters

• Controlled extension: the coil expands and retracts with the sensor arm, so the conductors are never over-stretched during steering or screed movement.
• Clean signal path: shielded conductors keep CAN feedback stable, which helps the operator hold an even mat thickness.
• Heat and abrasion resistance: the outer jacket stands up to high surface temperature, dust, vibration and daily mechanical wear on site.
• Fast service: the 8 pin 7 hole plug removes the need for adapters, cutting replacement time during a short maintenance window.

Technical parameters

When to replace the sensor cable

Most cable failures show up as small symptoms before the machine stops working. A sensor that reads low or high for a few seconds, a thickness display that jumps when the arm moves, or a connector that feels loose after cleaning are all signs worth checking. Cable damage is common in three situations: repeated folding at the same point, contact with the hot screed surface, and mechanical pulling when the sensor arm is folded for transport. Replacing the cable early avoids a mid-lane stop and keeps the paving train moving.

Stock and supply for road construction fleets

Benit is based in Taicang, Jiangsu, and supplies after-market parts for asphalt pavers, milling machines and road rollers to customers in Canada, France, the United States, Germany, Dubai and Brunei. The company supports contractors with routine maintenance parts, overhaul components and technical service, and can ship by air, rail or sea depending on the destination and urgency of the job.
