The SMD20 is a state-of-the-art rotational speed monitor engineered for industrial applications. Designed to measure the speed of any transmission shaft between 1–999 RPM, it ensures consistent performance and prevents mechanical failures. Its rugged construction and customizable process connections make it a reliable solution for factories, production lines, and automation systems.
Key Features
- Accurate RPM monitoring with micro-switch SPDT output
- Direct coupling via 4 equidistant ø6 holes on a ø90 mm pitch circle
- High operational safety in potentially explosive environments
- Compatible with high-temperature operations up to 120°C
- Optional visual display for real-time speed verification
Design & Functionality
Built with a die-cast aluminum casing and AISI 303 stainless steel shaft, the SMD20 combines durability with precise performance. Its sealed bearings and dust-tight retaining ring ensure long-lasting reliability. Installation is simplified without the need for special tools, enabling quick deployment across industrial setups.
Total Crossed Beams
The SMD20 uses an intrinsically synchronized design that ensures every beam is monitored accurately. This prevents misalignment and guarantees the sensor’s reliability even under heavy operational loads.
Beam Pitch Options
With a standard ø90 mm pitch circle and flexible mounting options, the SMD20 supports both direct and bracketed installations. This flexibility allows seamless integration into existing machinery setups.
Intrinsic Synchronism
The sensor maintains intrinsic synchronism, ensuring real-time monitoring and instant contact closure when speeds deviate from preset values. This protects equipment from mechanical strain and ensures operational continuity.
Operational Advantages
- Enhances industrial safety and compliance with ATEX and UKCA standards
- Prevents downtime with automated RPM alerts
- Reduces maintenance costs through early detection of anomalies
- Provides reliable performance in harsh conditions with IP65 protection
The SMD20 is an essential tool for industrial automation, mechanical systems, and high-precision manufacturing environments. Its combination of reliability, safety, and customization options makes it the preferred choice for engineers and operators seeking superior speed monitoring solutions.
