SG-E1-12 Equivalent & Substitute Parts

Part Overview

The SG-E1-12 is a panel-mounted pushbutton switch manufactured by Panasonic Industrial Automation Sales. It features a 3PST-2NC/1NO circuit configuration with On-Off/Off-On switching function, rated for 10A AC at 110V and 8A DC at 24V. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for system maintenance and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SG-E1-12 is determined by strict equivalence across the following critical parameters:

• Circuit configuration: 3PST-2NC/1NO
• Switch function: On-Off, Off-On operation
• Current rating: 10A minimum at AC voltage
• Voltage rating: 110V AC and 24V DC
• Mounting interface: Panel mount, front-facing with 22.30mm circular cutout
• Termination: Screw terminal connection
• Environmental protection: IP65 rating
• Regulatory compliance: RoHS compliance

The A22E-M-12 from Omron Automation and Safety meets all specified parameters and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The A22E-M-12 is a direct functional substitute for the obsolete SG-E1-12. Both components meet identical electrical specifications for circuit configuration, current and voltage ratings, and mounting interface requirements. The A22E-M-12 maintains active product status with current manufacturing support, addressing the obsolescence of the original part.

Compliance certifications are equivalent: both components are RoHS compliant and carry MSL 1 rating. The A22E-M-12 carries ROHS3 compliance and REACH Unaffected status, providing enhanced regulatory documentation.

The A22E-M-12 demonstrates improved environmental performance with oil and water resistance (versus water resistance alone) and an extended operating temperature range (-20°C to 70°C versus -25°C to 60°C). DC current rating is also higher at 10A versus 8A, providing additional margin in DC applications.

Frequently Asked Questions (FAQ)

Q: Can the A22E-M-12 directly replace the SG-E1-12 in existing installations?

A: Yes. Both components share identical circuit configuration (3PST-2NC/1NO), switching function, current and voltage ratings, panel cutout dimensions (22.30mm circular), and screw terminal termination. Physical mounting and electrical interface are equivalent.

Q: Are there differences in environmental protection?

A: Both components carry IP65 rating. The A22E-M-12 specifies oil and water resistance, while the SG-E1-12 specifies water resistance. This represents an enhancement in the substitute part.

Q: What is the significance of the operating temperature range difference?

A: The SG-E1-12 operates from -25°C to 60°C, while the A22E-M-12 operates from -20°C to 70°C. The substitute part provides a wider upper temperature limit. Applications requiring operation below -20°C would require verification of the original part's necessity.

Q: Are packaging considerations relevant to substitution?

A: The SG-E1-12 is supplied with unspecified packaging. The A22E-M-12 is supplied in bulk packaging and includes 3 pcs per unit: 1 switch, 1 locking ring, and 1 nut. Verify that included hardware meets installation requirements.

Q: What is the regulatory compliance status of each part?

A: Both components are RoHS compliant with MSL 1 rating. The A22E-M-12 carries ROHS3 compliance and REACH Unaffected status, providing current regulatory alignment.
