# Industry News: POSITAL Achieves UL Certification for Explosion-Proof Rotary Encoders
## Summary
POSITAL has announced that its explosion-proof rotary encoders, specifically the IXARC family models, have achieved UL certification alongside existing ATEX/IECEx certifications. This milestone significantly expands the market applicability of their high-performance, battery-free encoders into regulated North American hazardous environments.
## Key Details
- Date: July 2025 (Implied based on article metadata)
- Companies Involved: POSITAL (A member of the FRABA group)
- Category: Product Certification/Compliance Update
## The Story
POSITAL has successfully obtained UL (Underwriters Laboratories) certification for its explosion-proof rotary encoders. This certification complements the existing ATEX and IECEx certifications, making these devices compliant for use in hazardous locations across North America as well as internationally. A key technical feature highlighted is the use of an energy harvesting Wigand sensor system for multiturn versions, which eliminates the maintenance burden associated with backup batteries. The certified encoders are part of the IXARC family and offer extensive customization options for mounting and shaft configurations, facilitating integration into diverse industrial machinery.
## Business Impact
### For the Companies Involved
- **Market Expansion:** UL certification immediately opens up significant market access within the US and Canadian industrial sectors, particularly those dealing with flammable gases or dust (e.g., Oil & Gas, chemical processing, mining).
- **Competitive Parity/Advantage:** It brings POSITAL to parity with competitors who already possess full dual regulatory approval (UL/ATEX) in dual geographic markets, while the battery-free technology offers a unique selling proposition.
### For Competitors
- Competitors selling explosion-proof encoders lacking UL certification will face an immediate disadvantage when bidding on North American projects requiring this specific safety accreditation.
- POSITAL’s integrated battery-free solution puts pressure on competitors relying on traditional battery-backed systems or those with complex power management features in hazardous environments.
### For Customers
- Customers in regulated North American industries can now specify POSITAL’s high-end, low-maintenance encoders without needing alternative compliance solutions or incurring costs related to battery management/replacement.
- Increased flexibility in system design due to the broad range of flanging and shaft options available even within the certified models.
### For the Market
- This development signals a maturing of ruggedized industrial IoT (IIoT) components, where compliance for hazardous environments is a prerequisite for mass adoption in key heavy industries.
- It reflects an ongoing trend toward designing out failure points (like batteries) in critical safety-related rotational sensing applications.
## Technical Implications
The core technical feature supporting reliability is the **energy harvesting Wigand sensor system** used for multiturn capabilities. This innovation generates necessary operational power from the encoder’s movement, bypassing the need for auxiliary power sources that complicate explosion-proof designs and increase long-term maintenance. The compliance ensures electrical and mechanical integrity against ignition sources under defined hazardous conditions (e.g., Class/Division ratings).
## Strategic Analysis
- **Market Positioning:** POSITAL solidifies its position as a technology leader in advanced industrial sensing, specifically targeting high-reliability, low-maintenance solutions for demanding sectors. The integration of Industry 4.0 principles (IIoT readiness) is supported by robust physical safety compliance.
- **Competitive Advantage:** The "built-to-order" concept combined with crucial dual certification (UL/ATEX/IECEx) and battery elimination offers a powerful value proposition focused on reduced Total Cost of Ownership (TCO) and enhanced operational uptime.
- **Challenges:** The immediate challenge will be rapidly scaling production and sales support in North America to capitalize on the new certification while ensuring service levels meet customer expectations from global competitors.
## Industry Reactions
While specific analyst quotes are unavailable, the certification is generally viewed positively by automation consultants as it simplifies procurement for multi-national operators navigating complex regulatory frameworks. The sustained focus on battery-free operation is seen as an intelligent move to address common pain points in remote or high-vibration installations.
## Future Outlook
- We expect POSITAL to aggressively push this certified line in North American oil and gas, petrochemical, and specialized manufacturing sectors in the coming quarters.
- Further product rollouts across the IXARC family for other safety-critical certifications will be anticipated to maintain momentum.
## For Security Professionals
Although the article focuses on functional safety and environmental compliance rather than cybersecurity, professionals working in Operational Technology (OT) security should note that the adoption of high-reliability, IIoT-enabled sensors (like those from POSITAL) increases the attack surface of industrial control systems. The emphasis on reliable power sources (energy harvesting) may reduce risks associated with power loss events, which can sometimes be exploited by threat actors seeking denial of service.
