OMRON V680-HAM91/HAM81 — RFID Systems
Omron V680-HAM91/HAM81: amplifier-integrated RFID ID Flag Sensor; NPN (HAM91) or PNP (HAM81) output, 24 V DC, 3.5 W, DIN track, 90 × 30 × 65 mm.
Status: In production
Brand: Omron
Product: Amplifier-integrated RFID controller (ID Flag Sensor), NPN/PNP output
Output: HAM91: NPN open collector; HAM81: PNP open collector; 30 V DC, 20 mA max.
Power supply: 24 V DC, 3.5 W (150 mA max.)
Dimensions: 90 × 30 × 65 mm
Degree of protection: IP40
The V680-HAM91 and V680-HAM81 are ID Flag Sensors with a built-in amplifier; V680-HS-series antennas connect directly without a separate amplifier; the host is connected through transistor inputs and open-collector outputs. The HAM91 has NPN open-collector and the HAM81 PNP open-collector outputs; outputs are rated 30 V DC and 20 mA max., with a residual voltage of 2 V max. On the inputs, OFF voltage is 15–30 V DC, ON voltage 0–5 V DC and input impedance 8.2 kΩ. The unit is powered from 24 V DC and consumes 3.5 W (150 mA max.) excluding external I/O line current.
Connection is made with the V680-A60 interface cable; normally 2 cables are required per unit, and 1 cable is sufficient if writing, address shift or the noise check function is not used. The cable can be extended to 10 m max.; connectors are not waterproof, so mount the unit in a control box if water may splash onto it. The unit measures 90 × 30 × 65 mm, weighs approx. 130 g, mounts on a DIN track and has IP40 protection. With a V680-D1KP66T, read range is 5.0–47.0 mm with a V680-HS65 antenna. Operating temperature is −10 to 55 °C.
