Features Applications And Selection Guide
Discover M12 D code 4 pin to RJ45 industrial Ethernet cables for connecting compatible readers, switches, and industrial PCs. Review interface matching, pin mapping, cable length, and selection criteria, including KEYENCE OP-87230, OP-87231, and OP-87232 reference models and custom cable solutions.
Product Introduction
What Is an M12 D Code 4 Pin to RJ45 Industrial Ethernet Cable?
An M12 D code to RJ45 industrial Ethernet cable connects an industrial device's M12 D code Ethernet port to RJ45 network equipment.
Its threaded M12 connector provides a secure and keyed connection, while internal conductors carry Ethernet signals between compatible devices. This interface is commonly used for two-pair Fast Ethernet, such as 100BASE-TX, unlike 8 pin M12 X code solutions for Gigabit Ethernet.
Why Do Industrial Readers Need a Dedicated Ethernet Cable ?
Industrial readers are used on production lines and conveyors. Ethernet cables must match interfaces and suit site routing, vibration, and continuous use.
The threaded M12 D code connector helps secure connections, while cable design supports signal integrity. With EMI present, check shielding, termination, and grounding. A verified M12 D code 4 pin to RJ45 cable helps reduce wiring errors and simplify maintenance.
How to Select the Right M12 to RJ45 Industrial Ethernet Cable
Before ordering, verify the reader model, M12 and RJ45 interfaces, connector type, cable length, Ethernet speed, shielding, and pin mapping. For KEYENCE SR-1000/SR-2000, verify OP-87230/31/32 against official specs; request wiring and continuity tests for custom or wholesale orders.
Core Product Value
◆ Improve Interface Matching Accuracy
The M12 D code 4 pin to RJ45 cable joins two network interface formats. Clear coding and pin mapping help reduce improvised adapters, wiring errors, and specification mismatches in industrial installations.
◆ Simplify Wiring and Maintenance
A standardized Ethernet cable reduces on site cable fabrication and temporary wiring changes. Consistent lengths, connector designs, and clear labels support bills of materials and spare parts management.
◆ Support Reliable Network
Matched connectors, correct pin mapping, and proper installation help this Ethernet cable establish a physical link that meets equipment requirements. Suitable shielding and termination can also limit interference risks.
◆ KEYENCE Cable and Reader Compatibility
This cable is a compatible alternative to KEYENCE OP-87230, OP-87231, and OP-87232 cable for KEYENCE SR-1000 and SR-2000 readers. It supports reliable Ethernet links when interfaces and wiring match.

Product FAQ
Does This Cable Support Gigabit Ethernet ?
M12 D code 4 pin links are commonly used for Fast Ethernet, not Gigabit Ethernet. Check device specifications and cable design; Gigabit systems may require a different interface and cable.
Why Can Matching RJ45 Cables Fail to Communicate ?
The same RJ45 shape does not guarantee matching wiring or performance. Verify the approved pin map, cable rating, and connector contacts, then test continuity, miswiring, opens, and shorts.
Can This Cable Carry Power and I/O Signals Too ?
This cable is intended for Ethernet data, not general power, trigger, or I/O wiring. Verify the device's separate network and control interfaces, then select cables from its wiring diagram.
How Do I Check Industrial Suitability ?
Check the jacket, shielding, connector protection, bend limits, and electrical ratings against site vibration, EMI, oil, temperature, and abrasion. Review applicable test reports and certificates.
