Configured for high-frequency non-contact RFID tag communication in deterministic networks, the Omron V680-HS52-W (V680-HS52 Cylindrical Antenna) provides direct physical/electrical execution.

Model Nomenclature & Configuration

The V680-HS52-W designation identifies specific mechanical and electrical features within the V680 RFID platform.

• V680: Base high-frequency industrial RFID series operating at 13.56 MHz.
• HS: Head system antenna unit designed for read/write module integration.
• 52: M22 thread diameter form factor with standard sensing distance limits.
• W: Standard cable configuration featuring an integrated waterproof connector body.

Physical & Electrical Performance

Deterministic Network & Bus Integrity

The antenna assembly operates in tandem with V680 ID controllers to achieve deterministic network scan times across EtherNet/IP and Profinet architectures. Signal execution relies on stable backplane processing speed to maintain synchronization during high-speed tag pass-by operations. Noise immunity performance prevents firmware flash compatibility mismatches when routing raw RF data to upper-level PLC processors.

Supplied Components List

• 1x V680-HS52-W cylindrical antenna unit with attached standard waterproof cable
• 2x Brass mounting jam nuts for M22 threaded body securing
• 1x Standard mounting washer set

Mounting & Wiring Procedures

• Maintain a metal-free zone around the sensing head to prevent attenuation of the 13.56 MHz electromagnetic field.
• Torque the M22 mounting nuts to a maximum limit of 20 N m to prevent mechanical deformation of the outer housing.
• Ground the cable shield terminal at the controller side to avoid ground loops and low-frequency noise coupling.
• Secure the waterproof connector firmly without exceeding the minimal bending radius of the standard cable during execution.

Engineering Questions & Answers

• What is the primary purpose of the waterproof connector on the V680-HS52-W?

  It protects signal integrity at the terminal coupling from moisture ingress and fluid splash in wet processing areas.

• Does the antenna housing require grounding through the panel?

  No, internal shielding routes through the cable connector, but insulation must exceed 20 MOhm at 500 VDC from the case.

• How does external metal affect the M22 cylindrical body installation?

  Surrounding metals alter the inductance, which decreases read/write communication range if metal-free zones are ignored.

• Can the antenna cable be cut or spliced directly in the field?

  Splicing is prohibited because altering cable length disrupts impedance matching required for 13.56 MHz RF execution.

• What causes communication retries during high-speed tag reads?

  Extreme vibration or improper backplane synchronization timings between controller and PLC network modules cause retries.

• How does temperature affect the insulation performance?

  Operating outside -10 deg C to 60 deg C causes thermal stress, degrading insulation below the 20 MOhm threshold.

• What mechanical force limits apply to the antenna face?

  Impacts must not exceed 500 m/s2 in X, Y, or Z axes to prevent cracking the internal ferrite and coil structure.

• Is this antenna compatible with non-V680 series tag controllers?

  No, impedance matching and signal modulation limits restrict execution exclusively to Omron V680 controller channels.
