EE-SX405 Equivalent & Substitute Parts

Part Overview

The EE-SX405 is an optical through-beam sensor manufactured by Omron Electronics Inc-EMC Div, designed for PCB-mounted applications with a 3.4mm (0.134") sensing distance. This component is classified as obsolete, making identification of compatible alternatives essential for ongoing system support and new design implementations. The sensor operates on NPN open-collector output configuration with light-ON logic, suitable for industrial detection applications requiring compact form factors.

Key Parameters

Substitute Part Grouping Explanation

The EE-SX498 qualifies as a substitute for the EE-SX405 based on the following critical parameters:

• Sensing Method: Both employ through-beam optical detection
• Output Configuration: Both utilize NPN open-collector output with light-ON logic
• Mounting Type: Both are through-hole PCB-mounted components
• Voltage Supply Range: Both operate within 4.5V ~ 16V
• Current Supply: Both draw 3.2 mA
• Operating Temperature Range: Both function across -40°C ~ 75°C
• Regulatory Compliance: Both meet RoHS requirements

The primary difference is the sensing distance: EE-SX405 operates at 3.4mm while EE-SX498 operates at 3mm. This variance is within typical application tolerances for through-beam sensor implementations where precise gap distances are controlled by mechanical design.

Parameter Comparison

Engineering Selection Recommendations

The EE-SX498 is the manufacturer-recommended substitute for the obsolete EE-SX405. Both components share identical electrical specifications, output logic, and thermal operating ranges. The EE-SX498 maintains active product status with higher inventory availability (4354 pcs vs. 947 pcs), ensuring supply chain continuity. The EE-SX498 carries ROHS3 compliance and REACH affected status, representing current regulatory standards. The 0.4mm reduction in sensing distance (3.4mm to 3mm) is accommodated through standard mechanical tolerance adjustments in PCB-mounted sensor applications. Packaging format differs (tray vs. bulk), which may affect procurement and handling procedures but does not impact functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the EE-SX498 directly replace the EE-SX405 in existing designs?

A: Yes. Both components share identical electrical characteristics, output configuration, and mounting methodology. The sensing distance difference of 0.4mm requires verification that mechanical spacing in the application accommodates the reduced gap.

Q: What is the significance of the sensing distance difference between 3.4mm and 3mm?

A: The sensing distance defines the maximum gap between the emitter and receiver in through-beam configuration. The EE-SX498 operates at a slightly shorter distance. Applications must confirm that the physical spacing between optical paths remains within the 3mm specification.

Q: Are there compliance differences between the two parts?

A: The EE-SX405 is RoHS Compliant. The EE-SX498 is ROHS3 Compliant and REACH Affected, representing updated regulatory requirements. Both meet current environmental standards for electronic components.

Q: Does packaging format affect compatibility?

A: Packaging format (bulk vs. tray) affects procurement, storage, and handling procedures but does not impact electrical or mechanical compatibility. Component functionality remains identical regardless of packaging method.

Q: Why is the EE-SX405 listed as obsolete?

A: Product obsolescence indicates the manufacturer has discontinued production. The EE-SX498 represents the active replacement in the Omron optical sensor product line, ensuring continued availability and support.
