ODP-A Fiber optic displacement sensor

Multi-purpose fiber optic displacement sensor

Opsens’ ODP-A fiber optic displacement sensor is designed to offer high precision in the most demanding environments. Combined with Opsens’ WLPI signal conditioning technology (patent #7.259.862) and with the inherent advantages of fiber optics, the ODP A delivers unprecedented repeatability, resolution and reliability in the most adverse conditions such as high level of EM, RF, MR and microwave fields environments.

The standard model comes with 25 mm linear stroke length with one micron resolution. The ODP-A is mounted in a water splash-proof aluminium housing and a dielectric composite housing is offered in option. A convenient wall-mount attachment and a shaft spring return allow easy installation of the sensor.

The ODP-A is compatible with all Opsens’ WLPI signal conditioners. This precise and robust sensor, available with different optical cables length is customizable according to customer specific applications or for OEM-type applications.
