A01ES Configurable Switch Body E-Stop Non-Illuminated

Part Overview

The A01ES is a configurable switch body designed for emergency stop applications with a round, non-illuminated actuator. Manufactured by APEM Inc., this component serves as the base body for E-Stop switch assemblies and requires compatible contact blocks for full functionality. The A01ES is classified as obsolete, making identification of active equivalent parts essential for procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

The A01ES has one direct equivalent substitute: A01ESDM. This substitution is valid based on the following critical parameters that remain identical between both parts:

• Actuator Type: E-Stop, Round
• Illumination: Non-Illuminated
• Type: Maintained
• Panel Cutout Dimensions: 16mm (Round)
• Compatible Series: Apem, A01 (1 or 2 Pole)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The primary distinction is product status and packaging. The A01ESDM is an active production part available in tray packaging, whereas the A01ES is obsolete. Both parts maintain identical electrical and mechanical specifications, ensuring functional interchangeability within the A01 series ecosystem.

Parameter Comparison

Engineering Selection Recommendations

For new designs and ongoing procurement, the A01ESDM is the appropriate selection. As an active production part with identical electrical and mechanical specifications to the A01ES, it provides design continuity without functional compromise. The A01ESDM maintains full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Existing designs utilizing the A01ES can transition to the A01ESDM without modification, as both parts share identical panel cutout dimensions, actuator characteristics, and contact block compatibility within the A01 series. The shift from obsolete to active status ensures long-term supply chain stability and availability.

Frequently Asked Questions (FAQ)

Q: Can the A01ESDM directly replace the A01ES in existing assemblies?

A: Yes. Both parts share identical actuator type, illumination status, maintained operation, panel cutout dimensions, and contact block compatibility. No mechanical or electrical modifications are required.

Q: What is the primary reason for substitution?

A: The A01ES is classified as obsolete. The A01ESDM is the active equivalent, ensuring continued availability and supply chain reliability.

Q: Are there compliance differences between the two parts?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity levels.

Q: Does packaging differ between these parts?

A: Yes. The A01ESDM is supplied in tray packaging, while the A01ES packaging is not specified. This does not affect functional compatibility.

Q: Are contact blocks compatible across both part numbers?

A: Yes. Both the A01ES and A01ESDM support the same contact block configurations within the A01 series (1 or 2 pole options).
