Retro-reflective with M.S.R. function, Sensing distance When using the E39-R1: 100 mm to 6 m, Light-ON/Dark-ON selectable, Relay output (SPDT), Pre-wired models (2 m), Red LED (624 nm)
Improved visibility:
• A red LED that makes the spot visible.
• Large indicators that can be seen even from a distance.
• Improved operability.
(Enlarged sensitivity adjuster and operation selector)
• Freely selectable power supply input (24 to 240 VDC, 24 to 240 VAC).
(Additional types added to the DC type lineup.)
• Models with infrared LEDs are also available.
