Happy designing, and may your capsules always fire on cue!
(A concise, self‑contained guide for engineers, hobbyists, and procurement professionals who need reliable information on the YCT mechanical capsule and want to obtain its official technical documentation.) 1. What Is a “YCT Mechanical Capsule”? | Attribute | Details | |-----------|---------| | Full name | YCT (Y‑C‑T) Mechanical Capsule (also marketed as “YCT Precision Capsule”) | | Function | A sealed, spring‑loaded housing that protects and actuates miniature electromechanical components (e.g., relays, micro‑switches, solenoids, or MEMS devices). | | Typical applications | • Aerospace and satellite sub‑systems • Medical device actuation (infusion pumps, implantable drug‑delivery systems) • High‑vibration industrial equipment • Automotive safety systems (airbag deployment, seat‑belt pretensioners) | | Key selling points | • Hermetic sealing (often metal‑to‑glass or ceramic‑to‑metal) • Wide temperature range (‑55 °C to +125 °C) • Shock and vibration resistance (≥ 30 g, 2000 Hz) • Low magnetic signature (important for aerospace) • Customizable spring force and travel distance | Note: The “YCT” prefix is used by several manufacturers (e.g., YCT‑Tech, Y‑C‑T Precision, YCT Instruments). The exact part number is essential when searching for the datasheet. 2. Typical Technical Specification Snapshot | Spec | Typical Value* | |------|----------------| | Housing material | Stainless steel 316L, titanium, or high‑strength aluminum alloy | | Sealing method | Metal‑glass hermetic weld or ceramic‑to‑metal brazed seal | | Dimensions (Ø × L) | 10 mm × 20 mm – 30 mm × 80 mm (customizable) | | Spring type | Compression coil spring, stainless‑steel, pre‑loaded | | Travel (stroke) | 0.2 mm – 5 mm (adjustable) | | Force range | 0.1 N – 25 N (depending on spring) | | Operating temperature | –55 °C to +125 °C (extended to +150 °C for special alloys) | | Vibration rating | 30 g, 2000 Hz (per MIL‑STD‑810G) | | Leak rate | ≤ 1 × 10⁻⁹ atm·cc/s (He) | | Mounting | Threaded, flanged, or PCB‑compatible pads | | Compliance | RoHS, REACH, IEC 60529 (IP68) | yct mechanical capsule pdf download
