The DS18 sensor line was originally developed for the material handling industry. The DS18 family provides a base mounting option, a large output indicator, and no user adjustments; resulting in a simple, reliable, and rugged sensor with a low level of complexity for the customer. Features Sensing Modes The DS18 offers three mounting options: side mount, M18 front barrel, and M18 base mount. It has a large amber output indicator. LO / DO varies by sensing mode A new patented Wide Angle Polarized Retro (LPW) mode makes it even easier to align the sensor to the retro-reflector. Opposed mode (20 m) – E/R Fixed Field (50 and 100 mm) – FF Polarized Retro (3.5m) – LP Wide Angle Polarized Retro (3 m) – LPW Outputs: Complementary NPN / PNP, Light Operate / Dark Operate by model DC power: 10-30 V DC
