EQ-34 Equivalent & Substitute Parts

Part Overview

The EQ-34 is a reflective optical sensor manufactured by Panasonic Industrial Automation Sales, designed for proximity detection applications requiring infrared sensing at distances up to 78.7" (2m). This sensor features NPN open collector output, operates across a 10V to 30V supply range, and meets IP67 ingress protection standards for industrial environments. The EQ-34 is designated as Last Time Buy, indicating discontinued production status. Identifying equivalent substitute parts is necessary to ensure continued availability for new designs, maintenance applications, and system replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the EQ-34 is determined by the following critical parameters:

• Sensing Method: Must be reflective to maintain functional equivalence
• Sensing Distance: Must accommodate or exceed the 78.7" (2m) requirement
• Voltage Supply Range: Must be compatible with or encompass the 10V ~ 30V operating range
• Response Time: Must meet or exceed the 2ms specification
• Output Configuration: Must support NPN operation for circuit compatibility
• Light Source: Must utilize infrared technology
• Ingress Protection: Must maintain IP67 rating for environmental sealing
• Operating Temperature: Must cover the -20°C ~ 55°C range
• Connection Method: Must use cable-based connection

The EQ-511 qualifies as a substitute based on these parameters, with adjustable sensing distance capability that exceeds the fixed 2m distance of the EQ-34.

Parameter Comparison

Engineering Selection Recommendations

The EQ-511 serves as a direct substitute for the EQ-34 based on functional parameter alignment. Both sensors maintain ROHS3 compliance and identical operating temperature ranges. The EQ-511 operates within a narrower voltage supply window (12V ~ 24V versus 10V ~ 30V); applications requiring operation below 12V or above 24V must retain the EQ-34 or identify alternative solutions. The EQ-511 provides adjustable sensing distance capability (100mm ~ 2.5m) compared to the fixed 2m distance of the EQ-34, offering greater flexibility in deployment scenarios. Both sensors deliver 2ms response time and maintain IP67 environmental protection. The EQ-511 is designated as Active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy status of the EQ-34.

Frequently Asked Questions (FAQ)

Q: Can the EQ-511 directly replace the EQ-34 in existing installations?

A: The EQ-511 is functionally compatible when operating voltage remains within the 12V ~ 24V range. If the existing system operates at voltages below 12V or above 24V, the EQ-511 cannot be used. Verify the actual supply voltage in your application before substitution.

Q: What is the primary difference between these two sensors?

A: The EQ-34 provides a fixed sensing distance of 78.7" (2m), while the EQ-511 offers adjustable sensing distance from 100mm to 2.5m. The EQ-511 also supports both NPN and PNP output configurations, whereas the EQ-34 is limited to NPN open collector output.

Q: Are there packaging differences between the EQ-34 and EQ-511?

A: Both sensors are supplied in Box packaging. No mechanical or form factor incompatibilities exist between these models.

Q: Why is the EQ-34 marked as Last Time Buy?

A: Last Time Buy designation indicates the manufacturer has discontinued production. The EQ-511 represents the active product line continuation, ensuring long-term supply availability for new designs and replacements.

Q: What compliance certifications apply to both sensors?

A: Both the EQ-34 and EQ-511 are ROHS3 compliant. The EQ-511 is REACH Unaffected, while the EQ-34 shows Vendor Undefined REACH status. Both carry EAR99 ECCN classification and 8541.49.8000 HTSUS code.
