- Solid-state bipolar outputs, 150 mA maximum (continuous); sinking or sourcing hookup (usable simultaneously) 

- Totally encapsulated circuitry in a rugged, molded, plastic housing, rated NEMA 6P (IEC IP67) 

## WARNING: 

- Do not use this device for personnel protection 

- Using this device for personnel protection could result in serious injury or death. 

- • This device does not include the self-checking redundant circuitry necessary to allow its use in personnel safety applications. A device failure or malfunction can cause either an energized (on) or de-energized (off) output condition.

## Overview 

These rugged, powerful VALU-BEAM[®] opposed mode emitter/receiver pairs are designed to function in difficult environments. Excess gain is conservatively rated at 100x at an emitter-to-receiver separation distance of 3 meters (10 ft). 

Receivers will not false-trigger when pointed directly into a light source of 120,000 lux. Even under these conditions, a receiver will respond only to the light signal from its modulated emitter. Receivers are also immune to false triggering by sunlight reflected from water droplets. 

Receivers are immune to interference from flashing strobe lights as are typically found on plant lift trucks. Sensors are also immune to interference from a 5 Watt handheld transceiver, operating on specified frequencies, held 6 inches away from the sensor. 

Emitters and receivers that are to be used together must carry the same modulation code designation (A, B, or C). Sensor pairs of one code may be used alongside sensor pairs of another code, without interference or crosstalk. 

These sensors are ruggedly constructed in reinforced, molded, PBT polyester housings with replaceable acrylic lenses. Electronics are fully epoxyencapsulated. Sensors are constructed to NEMA 6P (IEC IP67) standards. These sensors will withstand temporary submersion. Operating temperature range is –20 °C to +70 °C (–4 °F to +158 °F). 

The sensors operate from 10 to 30 V dc (reverse polarity and short-circuit protected). Receivers have one solid-state light-operate PNP (sourcing) output and one solid-state light-operate NPN (sinking) output with a continuous load capability of 150 mA maximum (each output). A green indicator LED on each emitter lights whenever the infrared sensing beam is being emitted. Receivers have Banner's patented AID[™] (Alignment Indicating Device) system2, which lights a red LED whenever the output is conducting and pulses the LED at a rate proportional to the strength of the received light signal. 

## Sensor Codes and Response Times 

Emitters and receivers that are to be used together must carry the same code letter. Sensors of one code may be used side-by-side with sensors of another code, without interference or crosstalk. Sensor pairs carrying the same code must be separated by a minimum side-to-side distance of 22 inches (assuming an emitter/receiver separation distance of 10 feet; see beam pattern) to avoid crosstalk. 

The codes A, B, and C are used to designate different sensing pulse modulation frequencies and different intervals between sets of pulses. These design differences are necessary to enable differently coded sensor pairs to operate in close proximity without interfering with each other. 

These internal timing differences result in differing response times to light and dark signals in the differently-coded sensor pairs. See Table 1 on p. 2 for the response times when each sensor pair is operated alone, outside the field of view of another sensor pair. 

> 1 To order the 30 meter attached cable models, add a "W/30" to the standard cabled model number. For example, SM91EAN W/30.

|Response to light signal|20 ms|17 ms|28 ms|



Differently-coded sensor pairs in a common field of view may not perform as described in Table 1 on p. 2. To prevent unwanted response, a receiver operating under worst-case conditions may require some additional time to verify that the signal it sees is actually coming from its own companion emitter. These worst-case response times are given in Table 2 on p. 2.

Sensor Beam Opposed mode Modulated infrared, 880 nm 

Range 100x excess gain at 3 m (10 ft) emitter-receiver separation distance (see excess gain curve) 

Effective Beam Diameter 

- Response Time 12 to 28 ms, depending upon code 

- Output Confguration 

Bipolar solid-state dc PNP sourcing and NPN sinking outputs, light operate only (outputs conduct when the receiver sees the modulated light from its emitter) Output Rating 

   - 150 mA maximum (continuous, each output) 

   - OFF-state leakage current: 100 µA, maximum 

   - ON-state saturation voltage: < 1 V at 10 mA and < 2 V at 150 mA (PNP); < 200 mV at 10 mA and < 1 V at 150 mA (NPN) 

- 25 mm (1 in) 

- Sunlight Immunity 

Receivers may be pointed into a light source of 120,000 lux without false-triggering, and will still respond only to the infrared beam from their modulated emitters. Receivers will not respond to sunlight reflected from water spray droplets. 

Construction 

Reinforced black PBT polyester housing, electronics are epoxy-encapsulated Lenses: Molded, replaceable acrylic 

Connection 

- 2 m (6.5 ft) or 9 m (30 ft) attached PVC-jacketed cable; or integral mini-style quick disconnect (QD) fitting. QD connector housing and pins are isolated to 2500 V. 

- Indicators Top-mounted LED indicator. 

- Red LED on (receiver): Output is conducting Red LED flashing (receiver): Pulses at a rate proportional to the strength of the received light signal. Green LED on (emitter): Infrared sensing beam is "on" 

Operating Temperature Range –20 °C to +70 °C (–4 °F to +158 °F) 

- Environmental Rating NEMA 6P; IEC IP67 

## Water Immersion 

Emitters and receivers are rated NEMA 6P (IEC IP67). Sensors continue to operate during and after being submerged in water at a depth of 6 feet for a period of 48 hours. Immersion greatly reduces the efficiency of the lens, which results in greatly diminished sensing range. 

Strobe Light Immunity 

Receivers are immune to one Federal Signal Corp. "Fireball" model FB2PST strobe. EMI-RFI Immunity 

- Emitters and receivers will not respond to transmissions from a 5 Watt output handheld transceiver on the test frequencies of 464.500 and 151.625 MHz when the transceiver's antenna is held 6 inches or more away from the sensor.
