fast response speed, and high precision sensing. Through-beam Polarized Retroreflective Background Suppression (BGS) Detects fast-moving Fast objects 250 µs The 250 µs response speed is the fastest in its class. Closely-spaced objects on a fast-moving conveyor can be detected reliably. Small red laser beam Because the visible red laser is easy to see in both short (20...

SA1E-L Miniature Laser Photoelectric Switches (Built-in Amplifier) Class 1 laser. Fastest response in its class. Reliably detects fast-moving objects. • L ight source is a red laser (Class 1 by IEC 60825-1, 2007). Background Suppression (BGS) • L aser beams with high degree of straightness achieve a long sensing Through-beam range (30 m maximum).
SA9Z-K03. • The through-beam type requires two mounting brackets, one each for the projec tor and the receiver. • The SA9Z-K02 cannot be used for the connector models. • Contact IDEC about mounting brackets for the connector models. Slits (for through-beam) Package Item Slit Size Part No.
