Detailed LRF0609C Specifications

The technical material below is retained for this model only. Do not transfer a range, pulse, interface, mechanical or safety value from another 1535 nm product.

Specifications

LRF0609C is a 1535 nm pulsed distance-measurement module. Its assigned laser source is ER200; receiver-component data below come from the supplied APD-A13B001 R01 document. The three specification levels describe different assemblies and measurement conditions.

Source clarifications

The current PDF has an entry labelled “Range resolution ≤38 m” without defining that term. It is reported as a source entry, not reinterpreted as display increment, range accuracy or a proven multiple-return separation.

Pulse energy	200 µJ (source value; no minimum/maximum qualifier)
Optical pulse width	5 ns (FWHM)
Drive pulse width	<2.4 ms
Repetition rate	10 Hz (source operating point, not a stated range)
Pulse-energy stability	10% (definition/statistical method not stated)
Raw beam diameter	0.3 mm
Initial beam divergence	8 mrad (source value; no ≤ qualifier)
Transverse mode	TEM00
Operating / storage temperature	−40 to +65 �C / −55 to +85 �C
Package dimensions / mass	21 × 8 × 6.8 mm / 7 g
Component electrical entry	2 V, 10 A
Shock / vibration entries	1500 G, 0.5 ms / 20–2000 Hz, 20 G
Stated service life	>1 million shots; test conditions not supplied

The electrical entries describe the component drive, not the module supply input. Drive conditions and pulse-width definitions must follow the component document and the individual factory record. An optical pulse-width value is not a pump-drive duration.
