SHR AUTOSENSOR TECH LIMITED is a true manufacturer — not a trading company. R&D, automated production and 100% final testing under one roof in Shanghai, powering OEM engineering teams in EV, semiconductor ATE, medical and industrial applications.
Every SHR AUTOSENSOR relay and contactor is manufactured under a controlled process and verified before it ships, so the datasheet numbers are the numbers you get.
Practical application notes written by the team that builds the relays — updated regularly.
Contact selection, shielding and driver choices for clean low-level switching in robotic instruments.
