1. Product Introduction
300V 80ºC 7-Pin DIN Male to RJ45 Cable is an industrial-grade signal transmission cable designed for medium and low power signal and power mixed transmission. It uses a 7-pin DIN male connector (180° or 270° layout) to RJ45 (8P8C) interface, supports 300V voltage, and can work stably in a high temperature environment of 80ºC. Suitable for scenarios such as industrial control, professional audio, and medical equipment.
2. Product Advantages
High voltage support: 300V specification, suitable for mixed transmission of signal + low voltage power supply.
High temperature resistance: 80ºC temperature-resistant outer skin (PVC or silicone), suitable for industrial high temperature environment.
Anti-interference design: optional shielding layer (aluminum foil/braided mesh) to reduce electromagnetic interference (EMI).
High compatibility: 7-pin DIN interface is compatible with a variety of old equipment, and the RJ45 end can customize the line sequence.
Industrial-grade durability: gold-plated/nickel-plated contacts are anti-oxidation, and the wear-resistant outer skin prolongs the service life.
3. Application scenarios
Industrial automation (PLC control, sensor signal + power transmission)
Professional audio equipment (special interface connection of old synthesizers and mixing consoles)
Medical/laboratory instruments (resistant to high temperature disinfection environment, such as some monitoring equipment)
Aviation electronics (signal and low-voltage power transmission of airborne equipment)
Customized electronic projects (DIY hardware development, such as robot control)

1. Purchase suggestions
Confirm the DIN interface type: 180° (full circle) or 270° (semicircular) layout, which needs to match the equipment.
Select shielding type:
Unshielded (UTP): ordinary signal transmission.
Single shield (STP): aluminum foil layer to prevent general interference.
Double shield (FTP+braided mesh): high anti-interference, suitable for industrial environment.
Wire length and wire gauge:
Recommended length: 0.5m~10m (too long may cause signal attenuation).
Wire gauge: 22AWG~26AWG (the thicker the current carrying capacity, the stronger it is).
Special needs:
Customized pin definition is required (such as power supply + signal mixing for specific pins).
Oil-resistant/chemical-resistant outer skin (such as silicone material).
2. Precautions for safe use
Avoid high-frequency and high-voltage interference: Non-professional designs are not recommended to be laid in parallel with high-voltage cables.
Regularly check interface oxidation: Gold-plated contacts are more corrosion-resistant, but require regular maintenance.
Match device voltage: Confirm whether the device requires 300V withstand voltage (usually signal transmission ≤30V).
3. FAQ (Frequently Asked Questions)
Q1: Does it support data transmission (such as RS-232/485)?
A: The line sequence needs to be customized, and some 7-pin DINs contain serial communication pins.
Q2: What is the lifespan in high temperature environments?
A: 80ºC is a continuous operating temperature, and it can withstand 100ºC in a short period of time, but long-term high temperatures may accelerate aging.
Q3: How to distinguish signal lines from power lines?
A: The pin definition of the device needs to be provided (such as Pin 1-2 is +12V, Pin 3-4 is GND).
4. Summary
300V 80ºC 7-Pin DIN to RJ45 Cable is a multifunctional connection solution for industrial and professional fields, taking into account both signal transmission and low-voltage power supply requirements. Its high temperature resistance and anti-interference characteristics are suitable for harsh environments, but it must strictly match the device pin definition. When purchasing, pay attention to shielding requirements, wire gauge and outer sheath material, and customized scenarios.
Humanity Design
High-quality flame-retardant materials: polymer materials have the advantages of flame retardancy and high temperature resistance; phosphor bronze gold-plated/tin-plated, with the advantages of wear resistance and corrosion resistance. High-tech anti-oxidation technology: improve the anti-oxidation and anti-corrosion capabilities, and maintain the characteristics of the metal surface.
Using thickened oxygen free copper wire core effectively reduces resistance and makes the circuit less prone to overheating. Simultaneously coated with a fireproof layer, it remains safe and durable even in high-temperature and dry environments. Bold thread body, sturdy and resistant to bending, will not break after long-term use.
