EX-43T Equivalent & Substitute Parts

Part Overview

The EX-43T is a reflective optical sensor module manufactured by Panasonic Industrial Automation Sales, designed for non-contact object detection applications. This sensor operates as an NPN open-collector output device with a sensing distance range of 0.787" to 1.378" (20mm to 35mm) and is rated for 12V to 24V supply voltage operation.

The EX-43T carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain system continuity, ensure supply chain reliability, and support ongoing maintenance and replacement requirements for installed equipment.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EX-43T is determined by the following critical parameters:

• Sensing Method: Must be reflective to maintain functional equivalence in non-contact detection applications
• Output Configuration: Must be NPN open-collector with light-ON logic to ensure direct compatibility with existing control circuits
• Voltage Supply Range: Must support 12V to 24V operation for power supply compatibility
• Light Source: Must use Red LED to maintain optical wavelength consistency
• Ingress Protection: Must maintain IP67 rating for environmental sealing requirements
• Operating Temperature Range: Must support -25°C to 55°C for thermal environment compatibility
• Connection Method: Must use cable connection for installation compatibility
• Response Time: Must match or exceed 500µs specification for timing-critical applications

The EX-43 qualifies as a direct substitute based on these parameters. While the EX-43 offers an extended sensing distance range of 0.394" to 2.756" (10mm to 70mm), it maintains all critical electrical and mechanical specifications required for EX-43T replacement.

Engineering Selection Recommendations

The EX-43 is the direct substitute for the obsolete EX-43T. Selection is based on the following engineering criteria:

Product Status: The EX-43T is obsolete, while the EX-43 maintains active product status with current manufacturing support and availability (843 units in stock).

Compliance: The EX-43 provides enhanced RoHS compliance (ROHS3) compared to the EX-43T (RoHS Compliant), ensuring alignment with current regulatory requirements and supply chain standards.

Electrical Compatibility: All critical electrical parameters—supply voltage, output configuration, response time, and light source—are identical between the two models, ensuring direct functional replacement without circuit modification.

Mechanical Compatibility: Cable connection method, cable length, ingress protection rating, and operating temperature range are fully matched, supporting direct installation in existing equipment.

Sensing Distance Advantage: The EX-43 provides an adjustable sensing distance range of 10mm to 70mm, which encompasses the EX-43T range of 20mm to 35mm. This extended range provides greater flexibility for application tuning without requiring additional hardware changes.

Frequently Asked Questions (FAQ)

Q: Can the EX-43 directly replace the EX-43T without circuit modifications?

A: Yes. The EX-43 maintains identical electrical specifications including 12V to 24V supply voltage, NPN open-collector output with light-ON logic, 500µs response time, and Red LED light source. No circuit modifications are required.

Q: What is the difference in sensing distance between the EX-43T and EX-43?

A: The EX-43T operates at a fixed sensing distance of 20mm to 35mm. The EX-43 provides an adjustable sensing distance of 10mm to 70mm. Both models include adjustment capability, allowing the EX-43 to be configured within the EX-43T operating range.

Q: Are there packaging differences between these models?

A: The EX-43T is supplied without specified packaging, while the EX-43 is packaged in a box. Both models use identical cable connection methods and cable lengths (2m).

Q: Does the EX-43 meet current compliance standards?

A: Yes. The EX-43 is ROHS3 compliant, representing enhanced regulatory compliance compared to the EX-43T. Both models maintain IP67 ingress protection and operate across -25°C to 55°C temperature range.

Q: Is the EX-43 currently available?

A: Yes. The EX-43 maintains active product status with 843 units in current inventory, ensuring supply chain continuity for replacement and new installations.

Q: Are there any functional limitations when substituting the EX-43 for the EX-43T?

A: No functional limitations exist. The EX-43 provides equivalent or enhanced specifications across all critical parameters. The extended sensing distance range of the EX-43 provides additional application flexibility.
