How to Use JST SH1 x3 Female: Examples, Pinouts, and Specs

The JST SH1 x3 Female is a compact and reliable connector designed for use in electronic circuits. It features three female terminals, making it ideal for applications requiring secure and space-efficient wire connections. This connector is widely used in robotics, drones, IoT devices, and other compact electronic systems where size and reliability are critical.

• Connecting sensors, actuators, or modules in compact electronic devices
• Power and signal transmission in drones and robotics
• Interfacing with small PCBs or breakout boards
• Use in wearable electronics and IoT devices

The following table outlines the key technical details of the JST SH1 x3 Female connector:

The JST SH1 x3 Female connector has three terminals, typically used for power, ground, and signal connections. The pinout is as follows:

1. Wire Preparation: Strip the insulation from the wires to expose approximately 1-2 mm of the conductor. Ensure the wire gauge is within the supported range (32 AWG to 28 AWG).
2. Crimping: Use a compatible crimping tool to attach the crimp terminals to the wires. Ensure a secure and reliable connection.
3. Insertion: Insert the crimped terminals into the connector housing until they click into place.
4. Mating: Connect the JST SH1 x3 Female to its corresponding male connector. Ensure proper alignment to avoid damage.

• Wire Gauge: Use wires within the specified gauge range to ensure proper crimping and electrical performance.
• Current and Voltage Limits: Do not exceed the maximum current (1.0 A) or voltage (50 V) ratings to prevent overheating or damage.
• Secure Connections: Double-check that the terminals are fully inserted into the housing and that the connector is properly mated.
• Environmental Conditions: Avoid exposing the connector to temperatures or environments outside its operating range (-25°C to +85°C).

The JST SH1 x3 Female can be used to connect a sensor to an Arduino UNO. Below is an example of wiring and code for reading data from a sensor:

• Pin 1 (VCC): Connect to the Arduino's 5V pin.
• Pin 2 (GND): Connect to the Arduino's GND pin.
• Pin 3 (Signal): Connect to an analog input pin (e.g., A0) on the Arduino.

// Example code for reading an analog sensor connected via JST SH1 x3 Female
const int sensorPin = A0; // Signal pin connected to Arduino analog pin A0
int sensorValue = 0;      // Variable to store the sensor reading

void setup() {
  Serial.begin(9600); // Initialize serial communication at 9600 baud
}

void loop() {
  sensorValue = analogRead(sensorPin); // Read the sensor value
  Serial.print("Sensor Value: ");      // Print the sensor value to the serial monitor
  Serial.println(sensorValue);
  delay(500); // Wait for 500 milliseconds before the next reading
}

1. Loose Connections:

   • Issue: The connector feels loose or the circuit is intermittent.
   • Solution: Ensure the crimp terminals are securely attached to the wires and fully inserted into the housing.

2. Incorrect Pinout:

   • Issue: The circuit does not work as expected.
   • Solution: Double-check the pinout and ensure the connections match the intended design.

3. Overheating:

   • Issue: The connector or wires become hot during operation.
   • Solution: Verify that the current and voltage do not exceed the specified ratings.

4. Damaged Terminals:

   • Issue: The terminals are bent or do not make proper contact.
   • Solution: Replace the damaged terminals and ensure proper crimping.

• Q: Can I use this connector for high-power applications?

  • A: No, the JST SH1 x3 Female is designed for low-power applications with a maximum current rating of 1.0 A.

• Q: What crimping tool should I use?

  • A: Use a crimping tool compatible with JST SH1 terminals to ensure proper crimping.

• Q: Can I solder wires directly to the connector?

  • A: While possible, soldering is not recommended as it may damage the housing or reduce reliability.

• Q: Is this connector compatible with other JST series?

  • A: No, the JST SH1 x3 Female is specifically designed for the SH1 series and may not be compatible with other JST series due to differences in pitch and design.
