MX1.25mm Connectors, Cables & PCB Headers
MX1.25mm Connectors for Compact Wire-to-Board Assemblies
MX1.25mm connectors are compact wire-to-board components built around a nominal 1.25mm contact pitch. This Yoeruyo collection brings together cable assemblies, pre-crimped wires, connector housings, crimp terminals, PCB headers, extension leads and selected adapter cables for small electronic devices and space-conscious PCB designs.
“MX1.25” is a practical catalog term used for the 1.25mm connector products grouped on this page. It should not be treated as proof that every item is interchangeable with every Molex, PicoBlade, JST GH or other 1.25mm connector. Equal pitch is only one selection factor. Housing geometry, latch position, polarization, terminal design, mating depth and PCB footprint must also match.
What Is Included in the MX1.25mm Collection?
- Pre-wired cable assemblies: terminated leads for connecting sensors, modules, displays, batteries and control boards.
- Single-ended leads: a connector on one end with prepared or unfinished wire ends for integration into a custom harness.
- Double-ended and extension cables: selected male-to-female, same-family or conversion configurations for board and module connections.
- Housings and crimp terminals: loose components for custom pinouts, repair work and repeat cable production.
- PCB headers: selected straight, vertical, surface-mount or right-angle board interfaces.
- Connector kits: combinations of housings, contacts, headers or pre-crimped wires for prototyping and maintenance stock.
- Adapter harnesses: selected cables that bridge an MX1.25-style interface to another connector format when the listing specifies both ends.
Important Specifications to Compare
- Contact pitch: verify 1.25mm center-to-center spacing.
- Circuit count: match the exact number of positions required by the board or device.
- Mating interface: compare housing outline, latch, keying, polarization and contact location.
- Header orientation: identify top-entry, side-entry, straight or right-angle routing.
- Mounting method: distinguish through-hole and surface-mount PCB designs where applicable.
- Cable details: confirm wire gauge, length, conductor order, insulation and termination at both ends.
- Package contents: check whether the product includes housings, terminals, wires, headers or a complete assembly.
- Application ratings: use the electrical, temperature and material data shown on the individual product page.
Typical Uses for 1.25mm-Pitch Connectors
These compact connectors are considered for embedded controllers, sensor modules, small displays, battery-powered devices, robotics, drones, camera equipment, communication modules, portable instruments, consumer electronics and repair harnesses. A 1.25mm pitch offers a middle ground between ultra-fine 1.0mm connectors and larger 2.0mm or 2.54mm formats, but suitability depends on the complete mechanical and electrical design.
MX1.25mm vs. SH 1.0mm, ZH 1.5mm and PH 2.0mm
The defining difference is contact spacing: MX1.25 products use a nominal 1.25mm pitch, while SH-style connectors are commonly associated with 1.0mm, ZH-style products with 1.5mm and PH-style products with 2.0mm. A larger pitch generally produces a larger connector body, but pitch alone does not determine current capacity, durability or compatibility. Always compare the exact product specifications and dimensions.
How to Identify the Correct 1.25mm Connector
- Measure the distance across several contacts and divide by the number of spaces to confirm pitch accurately.
- Count the positions and inspect whether the contacts are arranged in one row or another configuration.
- Compare the housing shape, latch location, keying and mating direction.
- For PCB headers, verify pad layout, mounting method, entry direction and component height.
- For cables, verify wire order, length, gauge and termination on both ends.
- Check dimensional drawings or measurements before treating two 1.25mm products as substitutes.
Frequently Asked Questions
What does MX1.25mm mean?
On this store, MX1.25mm identifies a group of compact connector products with a nominal 1.25mm contact pitch. The term helps organize related cables, housings, contacts and headers, but each listing remains a product-specific mechanical interface.
Is MX1.25 the same as Molex PicoBlade?
Not automatically. Some products may be described with commonly searched industry references, but interchangeability must be established from the housing, terminal and header dimensions. Do not rely on pitch or a marketplace naming convention alone.
Is a 1.25mm connector compatible with JST GH?
Not necessarily. Two families can share a 1.25mm pitch while using different latch geometry, polarization, contact construction or PCB footprints. Compatibility should be confirmed for the exact mating pair.
Should I choose a complete cable or loose housing and terminals?
A complete cable is useful when its length, wire size and pin sequence already match the design. Loose components are better for custom harness lengths, nonstandard wiring orders, repairs or controlled production assembly.
What should procurement teams specify?
Specify pitch, positions, mating direction, housing and terminal style, PCB mounting method, wire gauge, cable length, pin sequence, quantity and required electrical or environmental ratings. A reference photo alone is not enough for reliable sourcing.
Technical Selection Guidance from Yoeruyo
Yoeruyo organizes 1.25mm connector products so engineers, technicians, makers and purchasing teams can compare relevant forms within one technical category. Use this page to narrow the format, then rely on the individual product listing for dimensions, ratings, included quantities and application-specific details.
