ZH1.5mm JST Connector — 1.5mm Pitch Wire Harness & Housing
ZH1.5mm JST Connectors — Precision 1.5mm Pitch Bridging Micro and Standard Connector Families
The ZH1.5mm series (JST ZH series, 1.5mm pitch) fills the critical gap between the ultra-fine SH1.0mm/MX1.25mm micro connectors and the more common PH2.0mm standard. With a 1.5mm pitch and 28AWG UL1571 wire, ZH1.5mm connectors deliver a compact footprint with slightly higher mechanical robustness than 1.0–1.25mm pitch alternatives. They are widely used in compact consumer electronics, portable medical devices, miniature camera modules, and precision instrumentation where a balance of size and durability is required.

Complete Product Range in This Collection
This collection covers the full ZH1.5mm ecosystem: pre-crimped single/double-head wire assemblies (10cm, 20cm, 30cm, same-direction and reverse-direction), SMT and DIP wafer connectors (straight, right-angle, vertical SMT, horizontal SMT), adapter conversion cables (ZH1.5 to SH1.0 / MX1.25 / PH2.0 / XH2.54 / Dupont 2.54mm), and bulk crimp terminal wires without housing for custom harness builds. All wire assemblies use 28AWG UL1571 insulated copper wire.
Ideal Applications
- Compact consumer electronics: earbuds, smartwatches, fitness trackers
- Miniature camera modules and endoscope sensor connections
- Portable medical monitoring devices and diagnostic equipment
- Precision instrumentation and laboratory measurement modules
- Compact IoT edge devices and wireless sensor nodes
- Miniature servo and actuator connections in robotics
- Adapter bridging between SH1.0mm/MX1.25mm and PH2.0mm/XH2.54mm systems
ZH1.5mm Connector Buying Guide
Step 1 — Confirm pitch compatibility: ZH1.5mm is not interchangeable with SH1.0mm, MX1.25mm, or PH2.0mm despite similar appearance. Always verify the pitch of your existing connector before ordering. Use a caliper to measure center-to-center pin spacing if unsure.
Step 2 — Choose pin count: ZH1.5mm is available from 2P to 10P. For power connections, 2P is standard. For data buses (UART, I2C, SPI), 3P–6P is typical.
Step 3 — Adapter cables: If you need to interface a ZH1.5mm device with a Dupont 2.54mm breadboard or XH2.54mm system, our ZH1.5-to-Dupont and ZH1.5-to-XH2.54 adapter cables provide direct plug-in compatibility.
Step 4 — SMT vs DIP: For PCB assembly, choose SMT wafers (vertical or horizontal) for reflow soldering. For through-hole hand-soldering, choose straight or right-angle DIP wafers.
Why Choose Yoeruyo for ZH1.5mm Connectors?
Yoeruyo maintains full stock of the ZH1.5mm ecosystem — a pitch size that many distributors carry only partially. Our ZH1.5mm products are CE and RoHS certified, manufactured to JST ZH series dimensional tolerances, and available in both small quantities for prototyping and bulk orders (100pcs+) for production. Custom cable lengths and multi-connector harness assemblies are available on request.
Frequently Asked Questions
Q: Is ZH1.5mm the same as JST ZH series?
A: Yes. ZH1.5mm refers to the JST ZH connector series with a 1.5mm pitch. Yoeruyo ZH1.5mm housings and terminals are dimensionally compatible with genuine JST ZH components.
Q: How do I tell ZH1.5mm apart from SH1.0mm and MX1.25mm?
A: The easiest method is to measure the center-to-center distance between adjacent pins: SH1.0mm = 1.0mm, MX1.25mm = 1.25mm, ZH1.5mm = 1.5mm. Visually, ZH1.5mm housings are slightly wider per pin than SH or MX. A digital caliper is the most reliable tool for confirmation.
Q: Can I use ZH1.5mm as an adapter between SH1.0mm and PH2.0mm systems?
A: Not directly — the pitches are different and housings will not mate across series. However, we offer adapter conversion cables (e.g., ZH1.5 to PH2.0, ZH1.5 to SH1.0) that allow you to bridge different connector families with a single cable assembly.
Q: What crimping tool is compatible with ZH1.5mm terminals?
A: The SN-03BM crimper is compatible with ZH1.5mm terminals for 28AWG (0.08–0.14mm²) wire. Available in this collection.
Q: Do you stock ZH1.5mm in bulk quantities?
A: Yes. Bulk orders of 100pcs+ are available for housings, terminals, and wafers. SMT wafers in quantities ≥500pcs are available in reel packaging for automated assembly. Contact us for volume pricing.
