JST ZH Connector 1.5mm Pitch Connector

  • The 1.5mm JST ZH Connector is compact, low profile connector commonly used in many servos, speed controllers and micro size receivers from consumer electronics to automotive, medical equipment and common household appliances.
  • Scondar offers 1.5mm JST ZH connectors with circuits varying from 2 to 17, on which the wire ends may be pre-stripped and tinned ready for soldering.
  • Enclosing this connector is a crimp style lock designed by Scondar and a special configuration which prevents users from inverted insertion.
  • Delivers up to a current rating of 1.0 A per contact and 50V for American Wire Gage (AWG) #28, #29,#30, #31 and #32

Offers Design Flexibility in a Variety of Configurations

Scondar offers a variety of 1.5 Pitch connectors with different models and in various dimensions, with top or side entry configurations which might suit your specific needs. Top entry configuration consumes a minimum of 3.5mm x 5.6 mm mounting height and depth, respectively; while side entry configuration consumes a minimum of 3.7 mm x 7.1 mm mounting height and depth, respectively.

A Variety of models to choose from

In addition to the above flexibility in configurations of the 1.5 mm pitch connector, Scondar also offers this connector with different number of circuits ranging from 2 to 17 which would suit your specific needs.

An Added Layer of Product Durability and Connector Reliability

No alloy was used in fastening the wires to the board, but through the use a crimping method, which makes if more flexible and mechanically stronger. The crimps are well engineered to be air-tight, preventing oxygen and moisture from reaching the metals, causing corrosion. Thus, the connector can be easily removed from the head without holding the wires. Furthermore, it prevents the cables from being easily disconnected due to entangled routing, heavy loads or vibration

Robust and Ruggedized Terminal Enhancements

Reliable electrical connection, even under conditions of low current and low voltage, is guaranteed with its two point contact design.

Compatibility with other displacement connectors

The ZH 1.5mm connector is completely compatible with ZR insulation displacement connector.

Surface Mount Option with Strong Solder Tabs

The two solder tabs assure that retention of header to PCB connection and act as a strain relief for the SMT solder tails minimizing the chance of solder joints breakage.

Optimized Safety Feature for Electrical Shock Hazard

With its improved product enhancement, the connector has the capability of withstanding voltage of 500 V AC per minute, which means to say that the insulation is sufficient to protect the user from electrical shock, overheating and fire.

Savvy Material and Finish

The header contact is made up of copper alloy, tin plated over a phosphor bronze material.

The housing is made of Nylon66 UL94V-0 natural ivory. These housings are available with or without protrusions.

The wafer is made up of Nylon66/46 UL94V-0.

The solder tabs are made up of brass, copper undercoated or tin-plated. These two solder tabs assure that retention of header to PCB connection and act as a strain relief for the SMT solder tails minimizing the chance of solder joints breakage.

Vast Temperature Range with Relatively Low Insulation and Contact resistance

There’s a dimple at the center of the contact which ensures positive contact and low contact resistance at all times. Insulation resistance and contact resistance are of 100 M Omega per minute minimum and 20M Omega maximum, respectively.

The temperature range for this connector is -25 degrees centigrade to +85 degrees centigrade. This range is based on the rise of temperature with increasing current.

Applicable in Chassis Wiring and Power Transmission Wiring

The 1.5 mm Pitch Connector can be used for AC and DC operations with a rated current of 1.0 amperes and 50 Volts. It is applicable in both chassis wiring and power transmission wiring.

Fine wires are usable

The connector can be used with the wires of AWG within the range of #28 to #32. This applies to wire diameters as small as 0.2mm to 0.32mm. Fine wires such as these can help the routing job.

Fully Shrouded Header

The pin header of the connector is wrapped with a thin plastic guide box around it good for preventing cable connection mishaps and it also provides good guidance for the mating connector.

Twin U-slot section

Twin U-slot section or twinaxial cable has a pair of insulated conductors where the conductors are run parallel with one another. This is commonly used in high speed balanced-mode multiplexed transmission in large computer systems, in which the signals are carried by both conductors in a U-shaped configuration. This ensures reliable connection and provides greater noise immunity.

Item Packaging

The housing and wafer package are available as 1000 Pcs per bag.

For terminal purpose the available package offers 15,000 pcs per bag.

For wire harness, you can ask for custom materials with 1000 Pcs/bag.

Fits Microelectronics Systems

1.5 mm pitch serves as the best choice for densely crowded electronics systems for its small, square-edged configuration, ruggedized and shock resistant feature.

Caters Power, Signal and Grounding Contact Needs

The 1.5 mm Pitch connector can either stand as power contacts, signal contacts or both as power and signal contacts or a signal and grounding contact. The wiring harness interconnects the PCB to various components that sends signals and power to other electronic devices.

Safe and Reliable

1.5mm pitch connectors ensures safety, system protection and performance with its bonded metallic conduits and multiple grounding points preventing fire hazards, component damage, overheating and possible electrocution.

The product does not contain restricted chemicals in concentrations not complying with ROHS standards. Thus, for its components, the products can be worked upon at high temperatures required by lead-free soldering.

Small Scale Robotics

1.5mm pitch connectors find its popularity in Robot construction kit parts, robot sensor systems, micro controllers and power systems often found in educational institutions and laboratories. Even for hobbyists and enthusiasts, this is an important connector that is a must have.

Popularity in Battery Connections

1.5mm pitch connectors is also popular in batteries such as in rechargeable battery packs, battery balancers, battery eliminator circuits. Battery connections rely on the ability of the current to pass reliable and solid current. This prevents overheating in the circuit and voltage drop.
