Omron D4V-8112Z Limit Switch - Equivalent & Substitute Parts

Part Overview

The Omron D4V-8112Z is a single-pole double-throw (SPDT) limit switch rated for 5A at 125V AC and 24V DC. This chassis-mount switch features a roller plunger actuator with screw terminal connections and IP65 ingress protection. The D4V-8112Z is classified as obsolete product status. Identifying equivalent substitute parts is necessary to maintain system continuity and ensure procurement availability for applications requiring SPDT limit switch functionality with identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D4V-8112Z is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Current rating (5A AC/DC)
• Voltage ratings (125V AC, 24V DC)
• Actuator type (Roller Plunger)
• Mounting type (Chassis Mount)
• Termination style (Screw Terminal)
• Ingress protection rating (IP65)
• Operating temperature range (-20°C to 60°C)
• Electrical and mechanical life specifications

The D4V-8112Z-N meets all substitution criteria as a direct equivalent part manufactured by Omron Automation and Safety within the same D4V series. The substitute maintains identical electrical performance, mechanical interface, and environmental protection specifications.

Parameter Comparison

Engineering Selection Recommendations

The D4V-8112Z-N is the direct substitute for the obsolete D4V-8112Z. Both parts are manufactured by Omron Automation and Safety and maintain identical electrical ratings, mechanical interfaces, and environmental specifications. The D4V-8112Z-N carries active product status, ensuring ongoing availability and supply chain continuity. Both parts are RoHS compliant, meeting regulatory requirements for electronic component procurement. The negligible variance in operating force (1000gf versus 999gf) and overtravel (0.158" versus 0.157") falls within normal manufacturing tolerances and does not affect functional equivalence for limit switch applications.

Frequently Asked Questions (FAQ)

Q: Can the D4V-8112Z-N directly replace the D4V-8112Z in existing installations?

A: Yes. The D4V-8112Z-N maintains identical electrical ratings (5A at 125V AC / 24V DC), circuit configuration (SPDT), actuator type (roller plunger), mounting interface (chassis mount), and termination style (screw terminal). Mechanical parameters including operating position, pretravel, differential travel, and overtravel are equivalent within manufacturing tolerances.

Q: What is the primary reason for substitution?

A: The D4V-8112Z is classified as obsolete product status. The D4V-8112Z-N is the active equivalent part from the same manufacturer and series, ensuring procurement availability and supply chain continuity.

Q: Are there any compliance differences between these parts?

A: No. Both the D4V-8112Z and D4V-8112Z-N are RoHS compliant with identical moisture sensitivity level (MSL 1 - Unlimited). Both parts meet the same regulatory and environmental standards.

Q: What are the critical parameters for limit switch substitution?

A: Substitution requires equivalence in circuit configuration (SPDT), current and voltage ratings (5A AC/DC, 125V AC, 24V DC), actuator type (roller plunger), mounting type (chassis mount), termination style (screw terminal), ingress protection (IP65), and operating temperature range (-20°C to 60°C).

Q: Are the mechanical specifications identical?

A: Mechanical specifications are equivalent. Operating force differs by 1gf (1000gf versus 999gf), and overtravel differs by 0.001" (0.158" versus 0.157"). These variations are within normal manufacturing tolerances and do not affect functional performance in limit switch applications.
