Custom Zero Motion Detection Systems
Detect When It’s Safe. Prevent Premature Access.
Custom Zero Motion Detection Systems that ensure equipment has come to a complete stop before allowing access.
A Zero Motion Detection System is a critical safety mechanism used to detect when motors, spindles, or rotating parts in industrial machinery have come to a full stop. It prevents guards or gates from opening, or operators from re-entering the hazard zone, until it’s 100% safe.
These systems are essential for preventing injuries caused by residual machine motion after shutdown. Whether you’re upgrading machinery or engineering a new line, Arrow’s motion-sensing solutions are tailored to your exact safety and compliance needs.

Why Zero Motion Detection Matters for Machine Safety
Zero motion detection technology is essential for safeguarding workers from hidden dangers that remain even after machinery powers down. By ensuring that equipment has fully stopped before access is granted, these systems help prevent injuries, improve compliance, and strengthen overall safety programs.
Key Advantages Include:
Our Turnkey Electrical Guarding Process
From concept to compliance, we can handle every step:

On-Site Assessment
Our TÜV-certified safety engineers at Arrow & Machine Safety Specialists conduct comprehensive risk assessments, reviewing your equipment against OSHA 1910.212, ANSI B11, ISO 13849, and ISO 14120 standards. We identify hazards and define the safeguarding strategy tailored to your operation.

Custom Design
Using advanced CAD and 3D modeling, we engineer guarding systems that integrate seamlessly with your equipment. Every design balances operator access, visibility, ventilation, and maintenance requirements while meeting regulatory standards.

Fabrication
Arrow fabricates components in-house using premium materials such as steel, aluminum, and polycarbonate. We deliver precision framing, gasketing, hardware, and electrical safeguarding devices built to perform in demanding industrial environments.

Installation
Our expert installation team integrates your system with interlocks, safety switches, sensors, and control devices for full reliability. We ensure that your guarding solution functions as intended without compromising productivity.

Testing & Validation
Post-installation, we verify safety performance and provide relevant compliance documentation. Our team also supports training, audits, and certification requirements, helping your facility stay inspection-ready and OSHA-compliant.
Common Applications & Industries
Our Zero Motion Detection Systems are ideal in any application with moving or spinning equipment:
