Description

The Rennsteig 500‑D‑1EC is a heavy‑duty, electronically‑controlled pneumatic crimping machine engineered for high‑volume production environments requiring consistent, repeatable, full‑cycle crimps. Designed for machined contacts, insulated and uninsulated terminals, and large‑gauge conductors up to 250 MCM, the 500‑D‑1EC provides precision performance with minimal operator input.

This EC‑equipped model adds electronic cycle control, ensuring uniform crimp quality across long production runs while maintaining the rugged reliability of the 500 Series platform.

Key Features

• Electronically Controlled (EC) Version Ensures consistent cycle timing, repeatability, and process stability for demanding production workflows.
• Full‑Cycle Pneumatic Operation Guarantees complete crimp cycles with no partial crimps or operator‑induced variation.
• Foot‑Pedal Activation Hands‑free operation improves throughput and reduces operator fatigue.
• Interchangeable, Non‑Adjustable Die Heads No calibration or adjustments required. Die assemblies and positioners swap quickly with no special tools.
• High‑Precision Crimping Machine tolerances held to +.001 / –.001 in. for consistent, MIL‑grade performance.
• Wide Application Range
  • Machined/turned contacts: 20 AWG – 4/0 AWG
  • Insulated terminals: 22 AWG – 4/0 AWG
  • Uninsulated terminals: 22 AWG – 250 MCM
  • Coaxial connectors: up to 1.5 in (38.1 mm) hex
• Industrial Build Quality Operates on standard shop air (90–115 PSI / 6.5–8.0 BAR) with a rugged 39‑lb chassis designed for continuous duty.
