E3X-SD6 Equivalent & Substitute Parts

Part Overview

The E3X-SD6 is a standard sensor amplifier manufactured by Omron Automation and Safety, designed for fiber optic applications with NPN output configuration. This unit operates on 12V to 24V supply voltage and is mounted on DIN rail. The product is currently obsolete, making identification of functionally equivalent active alternatives essential for system maintenance, upgrades, and new installations where this model is no longer available.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the E3X-SD6 is determined by the following critical parameters:

• Amplifier Type: Must be Standard
• Output Type: Must be NPN or NPN-compatible
• Operating Temperature Range: Must encompass or match -25°C ~ 55°C
• Voltage Supply Range: Must be compatible with or broader than 12V ~ 24V
• Mounting Type: DIN Rail preferred for direct replacement
• Manufacturer: Omron Automation and Safety (product family consistency)

The two identified substitutes meet these core criteria while offering active product status and current availability.

Parameter Comparison

Engineering Selection Recommendations

E3X-HD6 is the primary substitute for direct replacement applications. This part maintains identical voltage supply range (12V ~ 24V), matching operating temperature specifications, and provides NPN output with open collector configuration. The E3X-HD6 is active and in production, with RoHS3 compliance and REACH compliance status documented. Supply current is rated at 60 mA, which exceeds the original 40 mA specification, providing operational margin in most applications.

E3NX-FA6 serves as an alternative where broader voltage tolerance is beneficial. This part accepts 10V ~ 30V supply voltage, extending operational range below and above the original specification. The E3NX-FA6 maintains identical operating temperature range and MSL rating. Output type specification is not provided in available documentation; verification against system requirements is necessary for this substitute.

Both substitutes are manufactured by Omron Automation and Safety, ensuring consistency with the original product family and support infrastructure.

Frequently Asked Questions (FAQ)

Q: Can E3X-HD6 be used as a direct replacement for E3X-SD6?

A: Yes. The E3X-HD6 maintains the same voltage supply range (12V ~ 24V), operating temperature range (-25°C ~ 55°C), and NPN output configuration. The higher current rating (60 mA vs. 40 mA) does not prevent substitution in standard applications.

Q: What is the primary difference between E3NX-FA6 and E3X-HD6?

A: E3NX-FA6 provides extended voltage tolerance (10V ~ 30V) compared to E3X-HD6 (12V ~ 24V). E3X-HD6 specifies NPN open collector output and 60 mA supply current. E3NX-FA6 output type is not specified in available data.

Q: Does packaging type affect substitution?

A: Packaging (Bulk for E3NX-FA6, Box for E3X-HD6) does not affect electrical or mechanical compatibility. Packaging selection depends on procurement and inventory management requirements.

Q: Are both substitutes RoHS compliant?

A: E3X-HD6 is documented as RoHS3 compliant. E3NX-FA6 RoHS status is not specified in available documentation.

Q: What is the inventory status of these substitutes?

A: E3NX-FA6 has 936 pieces in stock. E3X-HD6 has 938 pieces in stock. Both are available as new original components.
