SMI30 Series receivers have a red LED alignment indicator that lights whenever the receiver "sees" its modulated light source. Emitters

have a red LED to indicate "power on". All LED indicators are mounted internally to preserve the waterproof integrity of the sensor

housing, and are visible from both the side and front of the sensor through the sensor's quad-ring sealed acrylic lens.

The innovative circuitry used in SMI30 Series emitters and receivers provides the best noise immunity of any self-contained opposed

mode sensor pair. For applications where optical crosstalk between sensors might be a problem, SMI30 Series emitters and receivers

are available with a choice of three modulation frequencies (frequency "A", frequency "B", or frequency "C"). This makes it possible to

use high-powered sensor pairs of different frequencies in close proximity to each other without crosstalk. (NOTE: frequency "A" is

standard; frequencies "B" and "C" are available by special order. An emitter and its receiver must be of the same modulation

frequency.) See the models table for a summary of models.

Each unit is supplied with two hexagonal jam nuts. A 30 mm clearance hole is required for mounting, and mounting bracket models

SMB30MM, SMB30S, and SMB30C are available. All models have a built-in standard quick-disconnect ("QD") connector. "QD" models

mate with 12-foot long model SMICC-312 or 30-foot long model SMICC-330 mini-type QD cable (sold separately from sensor).
