Product Overview
Keyence OP-75721 M12 Straight Connector Cable with Flying Leads for Photoelectric Sensors – Unused
This is a Keyence OP-75721 connector cable designed to link compatible Keyence photoelectric sensors to control panels, PLCs, or terminal blocks in industrial automation systems.
Keyence treats cabling as part of the sensor system, not an afterthought. The OP-75721 pairs a factory-terminated M12 connection at the sensor with flying leads at the panel end, giving installers a clean, predictable interface where it matters and flexibility where it is needed.
Product Condition
Unused, new old stock. The cable remains in the manufacturer’s packaging. Packaging shows minor signs of handling from storage only; the cable itself is unused and in clean condition.
Product Overview
The OP-75721 is a 2 meter M12 straight connector cable supplied as an accessory for Keyence built-in amplifier photoelectric sensors, including the PZ-G series. One end features a straight M12 4-pin plug for direct sensor connection, while the opposite end terminates in loose wire leads for field termination. The PVC-jacketed construction is intended for standard fixed industrial installations.

Frequently Asked Questions
Is this cable compatible with all M12 sensors?
No. Although it uses an M12 connector, the OP-75721 is designed for Keyence sensor pinouts. Compatibility should be confirmed using the sensor’s documentation.
What type of termination does the panel end use?
The panel end consists of loose wire leads, allowing direct termination to terminal blocks, I/O cards, or custom wiring harnesses.
What is the cable length?
The fixed cable length is 2 meters, approximately 6.6 feet.
Is this cable suitable for high-flex or drag-chain applications?
No. It is intended for standard fixed installations. Applications involving continuous motion or harsh chemicals should be evaluated against official Keyence specifications.
Is this cable unused?
Yes. This unit is unused new old stock and has never been installed.
A small but essential link in the sensor chain, this Keyence cable is ready to bring clean, OEM-correct wiring back to a system that depends on reliable detection.
