Required Overcurrent Protection

WARNING: Electrical connections must be made by

qualified personnel in accordance with local and

national electrical codes and regulations.

Overcurrent protection is required to be provided by end product application per

the supplied table.

Overcurrent protection may be provided with external fusing or via Current Limiting,

Class 2 Power Supply.

Supply wiring leads < 24 AWG shall not be spliced.

Construction

Aluminum housing, die cast zinc with black e-coat painted endcaps,

acrylic lens window

Environmental Rating

Meets IEC IP65

Connections

2 meter (6.5 ft) 5-conductor (with drain) pvc-jacketed attached cable or

5-pin Euro-style 150 mm (6 in) QD pigtail, depending on model

Operating Conditions

Temperature: −20 °C to +70 °C (−4 °F to +158 °F)

90% at +50 °C maximum relative humidity (non-condensing)

Application Notes

1. The best sensing resolution occurs within the center 80% of

the sensing range (Figure 1 on page 2).

2. Low-profile packages can be reliably detected.

3. Outputs are active while the light screen is interrupted.

4. For reliable detection, successive parts must be spaced up to

the total of ON-time plus OFF-time apart. (that is, 12

milliseconds for the LX12)
