OEM Controller for Fiber Optic Emergency Stop and Signaling Sensors

The OEM Controller contains a stable transmitter and a sensitive optical receiver, which operate over a Duplex LC multimode fiber optic link. The transmitter sends a constant light level via the transmit fiber which is interrupted when the fiber optic switch activates or the sensor beam is broken. The system is compatible with either OM1 (62.5µm/125µm) or OM2/OM3 (50µm/125µm) multimode fiber, to distances up to 1.5 km. The Controller operates over a wide 5-24 VDC range and provides a Digital Logic as well as Open-Collector Output for activating external relays.

The MR380 ZapFREE Signaling Sensor System outperform electromechanical and electronics-based switches and sensors, specifically where EMI immunity, high voltage isolation, inherent safety, MRI compatibility or operation over long distance is required. Applications include medical and MRI; transportation; oil, gas, and mines; petrochemical plants; high voltage transformer and switch gear; fire suppression systems; and process industries and instrumentation.

For ATEX applications and hazardous locations, the Signaling Sensors are classified simple mechanical devices and can be installed in any manner of explosive atmosphere – mines, gas and dust. The Controller outputs inherently safe, optical radiation and is approved for EPL Mb/Gb/Gc/Db/Dc applications.

For Functional Safety applications, depending on sensor type, the controller defaults to the emergency state when: (1) the optical path is blocked, (2) in case of a broken fiber, (3) a fiber is disconnected, or (4) loss of power to the controller link.

In small quantities, the MR380-0 OEM Controller is $250 and MR38X Sensors can range $350-$495, with typical lead time of stock to 2 weeks. Discounts are available for OEM applications. Special engineered versions are available for MRI applications, radiation and vacuum environments.
