Linear Encoder, LE

Solartron Metrology linear encoders are highly accurage optical gauges designed for use in applications where consistent sub-micron measurement is required. Accuracy is maintained along the entire measurement range. The Linear Encoders are available with both the iBox for TTL output and Orbit3 Compatibility.

A choice of 12mm or 25mm measurement ranges
Spring, free, pneumatic, cable release
Choice of IP65 or IP50 (probe only)
Up to 0.4µm accuracy
Up to 0.00125µm resolution
CE approved
Verification/calibration traceable to NPL (National Physical Laboratory)

Finger Lifter

The Finger Lifter is used for manual operation of spring push Linear Encoders and prevents heat being transferred to the shaft. Part Number 206678

Replacement Gaiters

replacement gaiters

Gaiters can be replaced when damaged. Only pneumatic push probes require gaiter rings.

Part Numbers:

Spring Push		Part Number	Pneumatic Push		Part Number
	LE/12/S	209562		LE/12/P	805098
	LE/25/S	205906		LE/25/P	804241

Clamping Collet

For use with all 8 mm clamping shaft sensors. The clamping collet distributes the clamping forces evenly around the shaft. Using the supplied grub screw, the probe can be loosened while holding the collet in place.

Imperial Adapter Sleeves

Adapter Sleeves can be used to increase the body diameter of 8 mm sensors to 9.512 (3/8"). Available in lengths A from 12 to 127 mm.
