RHEINTACHO Messtechnik GmbH (Freiburg, Germany) introduced the FQ series of plastic sensors for detecting rotational speed and direction. The sensors feature an IP69K protection class rating, which means they can withstand powerful, high-temperature water jets. The sensors offer different cable lengths, connectors, cable outlet directions, detection distances, and EMC. Standard insertion depths are 30, 35, and 45 mm. The sensors have a frequency range of 0.1 Hz to 20 kHz, and an operating temperature range of –40 to +140 °C.
