Joral LZ

Absolute Non-Contact Linear Transducer.

The Joral LP/LZ series non-contact linear sensors are IP69K wire-less boom extension/ linear position devices that eliminate the common faults which occur with conventional string pot/wire reel measurement devices.

Using a sealed magnetic track and a hall effect array the LP/LZ non-contact linear position devices detect linear extension in 1/4″ to 1″ resolutions. Made to replace the typical wire-reel found on booms and outriggers, the CAN J1939 linear sensors are IP69k and perform in the harshest environments.

The Joral magnetic non-contact linear sensor eliminates the need for wire reel devices that are prone to freeze, snap, or disconnect recoil. String pot mechanical extension devices can cost hours in wasted service time, but the Joral LP/LZ series are designed modular for simple installation and service.

The Joral LP30 is the compact incremental solution, while the LZBM and LZXS provide an absolute J1939 solution. The absolute LZ sensors are able to detect motion while powered down and upon restart reports absolute change from defined homed position.
