2. Multiple surge absorbing loop, effectively prevent surge damage.

3. High brightness, low consumption current, light receiving crystal, modulation emission, induction distance is very long, strong resistance to external turbulence.

4. High capacity relay output 3A/250VAC.

5. Rugged structure IP-67(selection) suitable for various environments.

6. Polaroid reflector type (A3G-4MRE) is more convenient for detection of bright objects.
