Omron D4V-8111Z Limit Switch - Equivalent & Substitute Parts

Part Overview

The Omron D4V-8111Z is a SPDT (Single Pole Double Throw) limit switch rated for 5A at 125V AC with chassis mount configuration and screw terminal termination. This switch features a round pin plunger actuator and IP65 ingress protection, designed for industrial automation applications requiring reliable position sensing and control.

The D4V-8111Z carries an Obsolete product status. Identifying equivalent substitute parts ensures continued availability for maintenance, repair, and new system designs where this switch specification remains functionally appropriate.

Substitute Part Grouping Explanation

Substitution of the D4V-8111Z is determined by strict equivalence across the following critical parameters:

Circuit configuration (SPDT)
Switch function (On-Momentary)
Current and voltage ratings (5A at 125V AC / 24V DC)
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-8111Z-N qualifies as a direct substitute based on matching all critical electrical and mechanical parameters within the D4V series. Variations in actuator type (round pin plunger versus roller plunger) and minor differences in operating force and overtravel remain within acceptable tolerance ranges for equivalent functional performance in standard limit switch applications.

Engineering Selection Recommendations

The D4V-8111Z-N is the manufacturer-recommended substitute for the obsolete D4V-8111Z. Both parts maintain identical electrical ratings, mechanical life specifications, and environmental protection ratings. The D4V-8111Z-N carries Active product status, ensuring ongoing availability and supply chain continuity.

Both parts are RoHS Compliant, meeting environmental and regulatory requirements for industrial automation applications. The D4V-8111Z-N is available in Bulk packaging, whereas the original part was supplied with standard packaging.

The actuator type difference (roller plunger versus round pin plunger) represents a design refinement within the D4V series. Operating force values remain functionally equivalent (999gf versus 1000gf), and overtravel specifications differ by only 0.001" (0.025mm), which is negligible for standard limit switch applications.

Frequently Asked Questions (FAQ)

Q: Can the D4V-8111Z-N directly replace the D4V-8111Z in existing installations?

A: Yes. Both parts share identical electrical ratings (5A at 125V AC / 24V DC), circuit configuration (SPDT), mounting type (Chassis Mount), and termination style (Screw Terminal). Operating characteristics remain equivalent within standard industrial automation tolerances.

Q: What is the difference between the round pin plunger and roller plunger actuators?

A: The actuator type affects the mechanical engagement profile. The D4V-8111Z uses a round pin plunger, while the D4V-8111Z-N uses a roller plunger. Both achieve the same operating position (1.024" / 26.0mm) and pretravel (0.060" / 1.5mm) specifications. Selection depends on the specific mechanical interface and cam profile of the application.

Q: Are there packaging differences between these parts?

A: The D4V-8111Z was supplied with standard packaging. The D4V-8111Z-N is available in Bulk packaging. This affects order quantities and handling but does not impact electrical or mechanical performance.

Q: Why is the D4V-8111Z marked as Obsolete?

A: The D4V-8111Z has reached end-of-life status. The D4V-8111Z-N represents the current production equivalent within the D4V series, offering the same functional specifications with Active product status and ongoing manufacturer support.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the D4V-8111Z and D4V-8111Z-N are RoHS Compliant, meeting environmental and regulatory standards for industrial applications.

Q: What is the operating temperature range for these switches?

A: Both parts operate across -20°C to 60°C, suitable for standard industrial environments without thermal management modifications.
