Product Details

Coherent PowerMax-RS LM-45 Laser Power Sensor Description：

Datasheet User's Manual

This PowerMax-RS LM-45 sensor is terminated in an RS232 cable that interfaces directly to a PC or industrial controller. A DB25 model (PN 1098320) is available.

These unique position sensing thermopiles display the position of the incident beam on the sensor disk, in addition to measuring power. This information allows the user to safely and precisely align the sensor and the beam being measured. This is particularly useful for non-visible beams.

SMA fiber adapter (PN 1098589) and FC/PC fiber adapter (PN 1098339) accessories are available when used with 1.035-40M Adapter Ring (PN 33-9432-000).
