Import Automatic Punch Bottom Dead Point Monitoring — Buy in Bulk from Supplier in China

The SC Series Bottom Dead Point Monitoring Device from Shandong Laien Optic-Electric Technology Co., Ltd. detects slugs trapped in dies by measuring displacement in the stripper plate at the bottom dead center. Models SC31 and SC32 use proximity sensors to compare the stripper plate’s position against a normal baseline, identifying anomalies caused by slugs as small as 20 to 40% of material thickness. The system operates on AC85-265V power and is unaffected by material thickness variations or temperature changes, as it recalibrates at every stroke using a microprocessor-controlled bottom-hold detection method.

The SC31 configuration includes a monitor, one proximity sensor, one proximity block, a connection cable, and a fixing mount, while the SC32 doubles the sensor and block components for broader coverage. Both variants feature a large digital display for real-time monitoring and automatic timing for periodic checks. The detection method relies on the physical principle that a slug caught in the die alters the stripper plate’s position, which the sensors register as a deviation from the expected bottom dead center.

This device is designed for press shops and metalforming operations where die protection and defect prevention are critical. It suits applications in automotive, appliance, and electronics manufacturing, where slug entrapment can damage tooling or produce defective parts. Buyers typically confirm compatibility with existing press machinery, sensor mounting options, and integration with production line controls before ordering. The supplier is based in Jining, Shandong, and can provide technical support for installation and calibration.
