WS4-3D2130 Equivalent & Substitute Parts

Part Overview

The WS4-3D2130 is a through-beam optical sensor manufactured by SICK, Inc., designed for photoelectric sensing applications with a sensing distance of 0" ~ 157.480" (0m ~ 4m). This sensor features Push-Pull output configuration supporting both NPN and PNP modes, operates across a supply voltage range of 10V ~ 30V, and utilizes red light (650nm) for detection. The WS4-3D2130 is classified as Obsolete and is no longer in active production. Finding equivalent substitute parts is necessary to maintain system functionality, ensure continued availability for replacement applications, and support long-term maintenance of installed equipment.

Substitute Part Grouping Explanation

Substitute parts for the WS4-3D2130 are identified based on strict alignment with the following critical parameters:

Core Compatibility Criteria:

• Sensing Method: Through-Beam (required for functional equivalence)
• Voltage Supply Range: 10V ~ 30V (required for electrical compatibility)
• Output Configuration: Push-Pull, NPN/PNP (required for control circuit compatibility)
• Connection Method: Connector, M8 (required for mechanical and electrical interface compatibility)
• Ingress Protection: IP66, IP67 (required for environmental protection equivalence)
• Operating Temperature Range: -40°C ~ 60°C (required for thermal environment compatibility)
• Response Time: 500µs (required for timing-critical applications)

Parameters Allowing Variation:

• Sensing Distance: Substitute parts may exceed the original 0m ~ 4m range, provided the minimum distance capability remains compatible with application requirements
• Light Source Wavelength: Red spectrum wavelengths (635nm ~ 650nm) are functionally equivalent for through-beam detection
• Product Status: Active status is preferred for long-term availability and support

The WSE4FP-21312100ZZZ meets all core compatibility criteria and is classified as an active product, ensuring continued manufacturing support and availability.

Engineering Selection Recommendations

The WSE4FP-21312100ZZZ is the recommended substitute for the obsolete WS4-3D2130 based on the following engineering criteria:

Product Status Compliance: The WS4-3D2130 is classified as Obsolete, indicating discontinued manufacturing and limited long-term availability. The WSE4FP-21312100ZZZ maintains Active product status, ensuring continued manufacturing support, spare parts availability, and technical documentation access.

Functional Equivalence: The substitute part maintains identical electrical and mechanical specifications across all critical parameters: supply voltage range (10V ~ 30V), output configuration (Push-Pull, NPN/PNP), response time (500µs), connection interface (M8 Connector), environmental protection (IP66, IP67), and operating temperature range (-40°C ~ 60°C).

Enhanced Capability: The WSE4FP-21312100ZZZ provides an extended sensing distance of 0m ~ 10m compared to the original 0m ~ 4m specification. This enhanced range does not compromise compatibility with existing applications and provides additional flexibility for future system modifications.

Optical Compatibility: Both sensors utilize red spectrum light sources (650nm original, 635nm substitute). These wavelengths are functionally equivalent for through-beam photoelectric sensing applications.

Inventory and Support: The substitute part is available with 975 pieces in new original stock, compared to 772 pieces of the obsolete original part, ensuring immediate procurement and long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the WSE4FP-21312100ZZZ directly replace the WS4-3D2130 in existing installations?

A: Yes. The substitute part maintains identical electrical specifications (10V ~ 30V supply, Push-Pull NPN/PNP output), mechanical interface (M8 Connector), and environmental ratings (IP66, IP67). No modifications to control circuits, power supplies, or mechanical mounting are required.

Q: What is the significance of the extended sensing distance (0m ~ 10m vs. 0m ~ 4m)?

A: The substitute part's extended range is a superset of the original specification. Applications requiring detection within the original 0m ~ 4m range will function identically. The extended capability provides additional flexibility for future applications without compromising backward compatibility.

Q: Are the light source wavelengths (650nm vs. 635nm) functionally equivalent?

A: Yes. Both wavelengths fall within the red spectrum and are functionally equivalent for through-beam photoelectric sensing. Optical detection performance and target material compatibility remain unchanged.

Q: Why is product status (Obsolete vs. Active) important for component selection?

A: Active product status ensures continued manufacturing, technical support, and spare parts availability. Obsolete products face limited inventory, discontinued documentation updates, and eventual unavailability. Selecting an active substitute ensures long-term system maintainability and supply chain reliability.

Q: Are there any mechanical or electrical modifications required for installation?

A: No. The M8 Connector interface, mounting dimensions, and electrical interface are identical. The substitute part is a direct mechanical and electrical replacement.

Q: What inventory considerations should be evaluated?

A: The WSE4FP-21312100ZZZ is available with 975 pieces in stock, providing immediate procurement capability. The original WS4-3D2130, with 772 pieces remaining, represents limited inventory of an obsolete product. Transitioning to the active substitute ensures long-term availability.
