Signal wires in sensor and limit switch setups fail for the same reasons — stiff insulation cracks under repeated movement, tin oxidation kills conductivity, and standard jacketing can’t handle oil or abrasion in tight machine housings. Every broken wire means unplanned downtime and a technician crawling under the equipment.This 2.5mm 3-core cable is built to fix that. Each core is 0.1mm² stranded tin-plated copper, wrapped in an ultra-soft PVC jacket with brown, black, and blue color coding for easy phase and signal identification. The outer diameter stays tight at 2.5mm so it routes cleanly through drag chains, conduit, and cramped sensor housings where space is limited.Core Specifications

Why this cable holds up where standard wire doesn’t
- Ultra-soft jacket handles constant flex. Tested for millions of cycles in cable carriers and drag chains. No cracking, no hardening — even in cold environments below -15°C.
- Tin-plated strands resist oxidation and vibration. Critical for low-voltage sensor signals where even micro-ohms of corrosion cause false readings or signal drop.
- Oil and abrasion resistant outer layer. Machine shops, packaging lines, and hydraulic equipment expose wiring to splashes and contact wear — this jacket takes it without swelling or peeling.
- 2.5mm OD fits where 3mm+ cables won’t. Sensor housings, micro-switch connectors, and narrow cable trays demand slim profiles. Three cores in 2.5mm gives you signal, power, and return without bulk.
Typical applications and industriesLimit switch wiring on CNC machines and conveyors. Proximity sensor and photoelectric signal runs. PLC I/O connections in control cabinets. Robotics arm signal cables. Packaging machinery, food processing lines, textile equipment, and material handling systems — anywhere 3-core low-voltage signal wiring gets routed through moving parts or tight enclosures.Ready for your spec?We produce this cable in-house with MOQ as low as 500 meters.
