Discover the ZMDC-21S1S Micro Connector: Compact, Reliable, and Versatile

The ZMDC-21S1S micro rectangular electrical connector is a game-changer for space-constrained applications. Its compact dimensions—5.65mm shorter in length and 1.24mm narrower than the ZMDM series—make it ideal for tight spaces where every millimeter counts. But don’t let its size fool you; this connector packs a punch. With a contact spacing of 1.91mm and row spacing of 1.65mm, it ensures reliable signal transmission. The conductor’s cross-sectional area ranges from 0.15mm² to 0.35mm², accommodating various wire sizes. Whether you’re designing medical devices, consumer electronics, or industrial equipment, the ZMDC-21S1S delivers exceptional performance. Plus, its impressive temperature range (-55°C to +125°C), high insulation resistance (5000 mΩ), and low contact resistance (8 mΩ) make it a versatile choice for demanding environments.
When precision matters, the ZMDC-21S1S connector steps up to the plate. Its mechanical life of 500 cycles ensures durability, while impact resistance (490m/s²) and vibration resistance (10-2000Hz, 196m/s²) make it suitable for rugged applications .Whether you’re designing automotive modules, aerospace systems, or smart appliances, this connector’s pressure resistance (800V) and relative humidity tolerance (40°C, 98%) keep things running smoothly. Say goodbye to bulky connectors; the ZMDC-21S1S combines space-saving design with uncompromising performance.
