How to Use JST SH1 x8 Female: Examples, Pinouts, and Specs

The JST SH1 x8 Female is a compact, 8-pin connector designed for secure and reliable wire connections in electronic circuits. Its small form factor makes it ideal for applications where space is limited, such as drones, robotics, and compact consumer electronics. This connector is part of the JST SH series, known for its precision and durability.

• Connecting sensors, actuators, and modules in compact devices
• Interfacing with microcontrollers and development boards
• Use in drones, wearables, and other space-constrained electronics
• Reliable connections in prototyping and production-grade circuits

The JST SH1 x8 Female connector is designed to meet the needs of modern electronics with the following specifications:

The JST SH1 x8 Female connector has 8 pins arranged in a single row with a 1.0 mm pitch. Below is the pin configuration:

Note: Pin assignments may vary depending on the specific application. Always refer to the datasheet or circuit design for proper pin usage.

1. Wire Preparation: Strip the insulation from the wires to expose 1-2 mm of the conductor. Ensure the wire gauge is compatible (32 AWG to 28 AWG).
2. Crimping: Use a compatible crimping tool to attach crimp terminals to the wires. Ensure a secure and reliable crimp for each wire.
3. Insertion: Insert the crimped wires into the connector housing until they click into place. Verify that all wires are securely locked.
4. Mating: Align the JST SH1 x8 Female connector with its corresponding male counterpart and gently push them together until they snap into place.

• Avoid Overcurrent: Do not exceed the 0.5 A current rating per pin to prevent overheating or damage.
• Secure Connections: Ensure the connector is fully mated to avoid intermittent connections.
• Environmental Conditions: Operate within the specified temperature range (-25°C to +85°C) for optimal performance.
• Wire Compatibility: Use wires within the specified gauge range (32 AWG to 28 AWG) for proper crimping and insertion.

The JST SH1 x8 Female connector can be used to interface sensors or modules with an Arduino UNO. Below is an example of connecting a sensor with a JST SH1 x8 connector to the Arduino:

• Pin 1 (VCC) connects to the Arduino's 5V pin.
• Pin 2 (GND) connects to the Arduino's GND pin.
• Pin 3 (Signal) connects to an Arduino digital input pin (e.g., D2).

// Example code for reading a digital signal from a sensor connected via
// a JST SH1 x8 Female connector to an Arduino UNO.

const int sensorPin = 2; // Pin connected to the sensor's signal line
const int ledPin = 13;   // Built-in LED for status indication

void setup() {
  pinMode(sensorPin, INPUT); // Set sensor pin as input
  pinMode(ledPin, OUTPUT);   // Set LED pin as output
  Serial.begin(9600);        // Initialize serial communication
}

void loop() {
  int sensorValue = digitalRead(sensorPin); // Read the sensor's signal
  if (sensorValue == HIGH) {
    digitalWrite(ledPin, HIGH); // Turn on LED if signal is HIGH
    Serial.println("Sensor activated!");
  } else {
    digitalWrite(ledPin, LOW);  // Turn off LED if signal is LOW
    Serial.println("Sensor inactive.");
  }
  delay(500); // Wait for 500 ms before the next reading
}

1. Loose Connections: If the connector is not securely mated, it may cause intermittent signals or power loss.
   • Solution: Ensure the connector is fully inserted and locked into place.
2. Crimping Problems: Poorly crimped wires can result in unreliable connections.
   • Solution: Use a high-quality crimping tool and verify each crimp before insertion.
3. Overcurrent Damage: Exceeding the current rating can damage the connector or wires.
   • Solution: Verify the current requirements of your circuit and ensure they are within the connector's specifications.
4. Pin Misalignment: Incorrect pin connections can lead to circuit malfunction.
   • Solution: Double-check the pin configuration and wiring before powering the circuit.

Q: Can I use this connector for high-power applications?
A: No, the JST SH1 x8 Female connector is rated for a maximum of 0.5 A per pin and is not suitable for high-power applications.

Q: What crimping tool should I use?
A: Use a crimping tool designed for JST SH series connectors to ensure proper crimping and secure connections.

Q: Can I solder wires directly to the connector?
A: While possible, soldering is not recommended as it may damage the connector housing and compromise reliability. Crimping is the preferred method.

Q: Is this connector compatible with other JST series?
A: The JST SH1 x8 Female connector is specifically designed for the SH series and may not be compatible with other JST series due to differences in pitch and design. Always verify compatibility before use.
