Part Number: CHW93058
Manufacturer
Eaton Crouse-Hinds
Part number
CHW93058
Quick Summary
The Eaton CHW93058 Conveyor Belt Alignment Switch provides reliable belt misalignment detection for industrial conveyors in hazardous locations. This addresses a common maintenance challenge where undetected skew accelerates belt wear, causes spine damage, and triggers costly downtime. It carries IEC-based certifications and Zone 21/22 hazardous location ratings, ensuring compliance and safe operation in demanding environments. With its two normally open and two normally closed contacts in a compact two-pole design, the switch integrates smoothly with existing safety circuits while delivering clear diagnostics. This combination translates to improved uptime, reduced maintenance costs, and greater overall reliability for belt-driven systems in challenging industrial settings.

Feature → Business Impact → Application: The CHW93058 uses a two-pole configuration with four contacts (two normally open, two normally closed), enabling flexible control schemes and safer start/stop logic for conveyors operating in hazardous zones. This reduces wiring complexity and provides robust interlock capabilities, which translates to fewer wiring errors and quicker commissioning on site. Application: suited for IEC-based conveyor lines in chemical plants or mining operations where safety and reliability are critical. Feature → Business Impact → Application: Precise dimensions (320.5 mm length, 100.5 mm height, 61.5 mm width) and a compact footprint maximize mounting options in space-constrained enclosures, facilitating retrofit projects and minimizing enclosure modifications. Application: retrofits and new installations in limited-space switchgear areas. Feature → Business Impact → Application: Area classification of Hazardous/Classified Locations (Zone 21/22) ensures compliance with industry regulations, reducing regulatory risk and potential downtime due to nonconformant components. Application: installations in potentially explosive atmospheres where safety certification matters. Feature → Business Impact → Application: Durable, purpose-built design for AFA IEC conveyor switches improves service life and lowers maintenance costs by resisting environmental stressors typical of harsh plants. Application: continuous operation in outdoor or wet plant environments. Feature → Business Impact → Application: Quickly replaceable CO/NC contacts and clear diagnostic outputs shorten maintenance cycles and speed fault isolation. Application: field service scenarios aiming for minimal conveyor downtime.

FAQs
CHW93058 is designed for hazardous locations and Zone 21/22 ratings, with a compact two-pole footprint and four contacts (2NO, 2NC). It installs on standard IEC conveyor frames and wires into existing safety circuits. Follow the datasheet guidance for enclosure sealing, mounting orientation, and wiring diagrams to ensure continuous compliance and reliable operation in challenging environments.
The unit features a two-pole configuration with two normally open and two normally closed contacts. It’s catalogued as CHW93058, with dimensions 320.5 mm (L) × 100.5 mm (H) × 61.5 mm (W) and a weight of 1.2 kg. It is intended for IEC-based conveyor systems and hazardous area installations, enabling flexible safety interlock schemes.
Yes. CHW93058 is part of the IEC Conveyor Switches family and is designed to integrate with standard safety circuits and interlock configurations. The 2NO/2NC arrangement provides versatility for logic integration, allowing seamless retrofit with current safety networks while maintaining compliance with Zone 21/22 requirements.
CHW93058 carries IEC-based certifications with Zone 21/22 hazardous location ratings, supporting operation in hazardous/classified locations. These certifications reduce regulatory risk, ensure safe operation around potentially explosive atmospheres, and align with industry standards for conveyor safety components used in mining, chemical, and other high-risk industries.
By preventing belt misalignment, CHW93058 reduces belt wear, minimizes unexpected downtime, and lowers maintenance costs. Its robust construction and quick-replace diagnostics shorten service windows, improving overall plant availability and extending belt life in harsh environments. The result is faster commissioning and a lower total cost of ownership for conveyor systems.
