The DUCIS SD-411/412/414 Series Bottom Dead Center Monitor (Computerized Slug Detector) is an advanced die protection device, specializing in detecting slugs or abnormal obstructions in progressive dies, especially high-speed stamping dies.
DUCIS SD-411/ 412/ 414 Controller
The device operates by installing a sensor on the lower die holder and a "proximity element" on the stripper plate. By continuously measuring the distance between these two parts at bottom dead center (BDC) with an accuracy of 1µm (0.001mm), the device can detect any minor changes. If a slug gets stuck, the stripper plate cannot return to the standard BDC position, and the device will immediately send a signal to stop the machine.
✨Key Features of the SD-41x Series
1. Extremely High Accuracy (1µm)
The device allows setting monitoring tolerance by micrometer (±1µm to ±99µm), enabling detection of the smallest changes, ideal for high-precision dies.
2. Superior Speed (1200 S.P.M)
Capable of responding to speeds up to 1200 S.P.M (strokes/minute), perfectly suitable for high-speed stamping presses.
3. Automatic Average Value Calculation
When starting operation, the machine will automatically take the measured values of the first 6 strokes to calculate the average height (Average) as the standard, making setup quick and accurate.
4. Multiple Protection Channels
The product line offers multiple options: SD-411 (1 channel), SD-412 (2 channels), and SD-414 (4 channels), allowing protection of multiple points on the same die or different dies.
🚨Intelligent Error Alarm System
When a problem is detected, the DUCIS SD-41x will immediately stop the machine and display a clear error code:
- •SP (Speed): Stamping press speed error (too fast or too slow) or loose sensor.
- •OP (Open Line): Broken wire or open sensor circuit, loose connector.
- •HI (High): Over-height error (slug present). The stripper plate is raised, exceeding the set tolerance.
- •LO (Low): Over-low error (die damage, broken punch). The stripper plate goes lower than normal, exceeding the tolerance.
- •ES (Error): Error from external sensors (if added) such as end of material, material jam, etc.
