B12B-ZR-SM4-TF – 12-Position 1.50mm Pitch ZH Series Header – JST

This JST ZH series surface-mount header enables reliable board-to-wire connections in space-constrained electronics. Featuring a compact 1.50mm pitch and secure detent locking, it ensures stable signal transmission for industrial and consumer applications. PCX supplies this active-status connector with guaranteed stock and fast shipping.

Key Features

• 12-position male pin header with all contacts loaded
• Ultra-fine 1.50mm pitch for high-density PCB designs
• Surface mount (SMT) termination with solder retention feature
• 1A current / 50V voltage rating (Tin-plated brass contacts)
• Shrouded 4-wall design for mating protection
• UL94 V-0 flammability rating (-25°C to 85°C operating range)

Technical Specifications

This single-row connector features circular male pins in a glass-filled polyamide housing (natural color). With a 5.00mm insulation height and 6.4mm mated stacking height, it maintains signal integrity in vibration-prone environments. The solder termination ensures robust PCB attachment, while the detent lock provides audible mating confirmation.

Typical Applications

• Industrial control systems
• Medical monitoring devices
• Consumer electronics internal wiring
• IoT sensors and modules
• Robotics and automation interfaces

About JST

JST (Japan Solderless Terminal) Manufacturing Co. is a global leader in connector technology with over 60 years of innovation. Their ZH series exemplifies precision engineering for miniature applications, meeting rigorous international standards for performance and safety.

Renowned for reliability in harsh environments, JST connectors undergo extensive validation testing. This commitment to quality ensures consistent mating cycles and electrical performance, making them the preferred choice for mission-critical electronics worldwide.

About Rectangular Headers

Rectangular pin headers form essential interconnects between PCBs and cables/wires, transmitting power and signals across electronic subsystems. Their standardized footprints enable modular design flexibility while reducing assembly complexity compared to custom solutions.

Selecting the correct pitch and current rating is critical for signal integrity and thermal management. Fine-pitch headers like JST’s ZH series address modern miniaturization demands without compromising durability, especially in automated manufacturing environments where SMT compatibility streamlines production.

Frequently Asked Questions

Q: What wire gauge pairs with this connector?
A: Designed for 28-32 AWG wires with compatible JST ZH crimp terminals.

Q: Is the housing resistant to soldering heat?
A: Yes, the glass-filled polyamide withstands standard SMT reflow profiles up to 260°C.

Q: Can I mate this with existing ZH receptacles?
A: Absolutely, it’s fully compatible with JST ZH female connectors sharing the 1.50mm pitch.

Q: Does the shrouding prevent reverse insertion?
A: The 4-wall design provides polarization but always verify orientation markings during assembly.

Q: What’s the mating cycle durability?
A: Rated for 30+ mating cycles when used within specifications.

Q: Are samples available before volume orders?
A: PCX offers small-quantity purchases for evaluation – contact our support team for options.
