Product Description:
The EK1960-2600 EK EtherCAT Coupler is manufactured by Beckhoff, which provides precise switching control with durable contact design and full compliance with industry standards. The relay coil of this coupler operates at 24 VDC nominal voltage to make it fully compatible with most control systems and power interfaces used in industrial setups.
This EK1960-2600 EK EtherCAT Coupler has a double-contact relay system with 1 normally open (NO) and 1 normally closed (NC) contact and facilitates both activation and feedback functions. The make contact (NO) of this coupler comprises AgNi material with 0.2 µm gold plating, which enhances the electrical conductivity, reduces arcing, and ensures stable operation in high-frequency switching. Similarly, the feedback contact (NC) uses AgNi with 5 µm gold plating, which provides longer contact life, better oxidation resistance, and improved signal reliability under prolonged use. The minimum switchable current provided to this coupler is 10 mA to allow precise operation with the lowest signal currents. According to IEC/EN 60947-5-1 standards, this coupler is capable of switching, rated DC13 at 24 VDC / 2 A for reliable functionality under various conditions.
The EK1960-2600 coupler has a maximum switching frequency of 20 switching cycles per second, which provides instant actuation in dynamic automation systems. This coupler functions successfully between -25 °C to +55 °C to operate under extreme and varying thermal conditions. This coupler functions at air pressures ranging from 750 hPa to 1100 hPa to provide installation convenience across different altitudes. This coupler also contains an IP20 protection level under IEC 60529, and resists air humidity of 5% to 95%, non-condensing, to ensure its long-term stability under varying industrial conditions. The shock resistance of this coupler is according to EN 60068-2-27 for shielding it from mechanical shocks.
Frequently Asked Questions about EK1960-2600:
Q: Why is gold plating used on both NO and NC contacts?
A: Gold plating enhances electrical conductivity and prevents oxidation, which is crucial for reliable signal transfer in low-current switching applications.
Q: How does the 24 VDC coil voltage improve system compatibility?
A: A 24 VDC coil matches standard control voltages in most automation systems, ensuring seamless integration without the need for voltage converters.
Q: How does the 5 µm gold plating on the NC contact benefit EK1960-2600?
A: It increases resistance to wear and corrosion, allowing the NC contact to maintain consistent performance over extended use.
Q: Why is the IP20 rating important in the EK1960-2600?
A: IP20 protects internal components from solid objects like fingers or tools, which is sufficient for installations inside control cabinets.
Q: How does the switching frequency of 20 cycles/s help in applications?
A: It supports fast relay actuation, making the EK1960-2600 ideal for systems that require rapid response times and high-frequency signal processing.
