Shielded 24-Position Plug for Discrete Wire Harnesses
The Hirose ST40X-24S-CV(30) is a 24-position plug from the ST series, built for shielded discrete-wire interconnects where signal integrity matters in a compact free-hanging package. The 0.020" (0.50mm) pitch packs 24 circuits into a single row, and the lever lock fastening gives a positive tactile mate that stays put under vibration — no chance of a half-turn dropout like you get with a threaded coupling.
What the Shield and Lever Lock Mean in Practice
The shielded construction is the headline feature — it wraps the 24 signal lines in a continuous EMI barrier, which matters when this plug sits in a harness alongside motors, drives, or switching power supplies. The lever lock is your insurance against the connector backing off from machine vibration; a half-turn loose on a threaded circular is a dropout, but the lever here gives a binary locked-or-not state you can verify by feel. Free-hanging (in-line) mounting means it floats with the cable rather than anchoring to a panel — plan your strain relief at the cable clamp, not the connector body.
24 Positions at 0.50mm Pitch — Routing the Discrete Wire Bundle
Each wire needs its own strain relief path; bundle the 24 conductors too tightly and the outer wires pull on the solder joints. The non-gender-specific contact type tells you the mating half uses the same contact geometry — check the Hirose ST series receptacle for the matching plug interface.
