1 AREA SENSOR SERIES mm Beam Pitch NA1-5 NA2 SF1-F NA40 SF1-N SF1-A Slim Body Fail-safe esign For General Use Supreme Fail-safe esign The system always check there is no internal circuit, no cable breakage, nor incident ambient light. If any error insists, the system turns the output relay OFF to force a machine to stop. Whatever malfunction occurs, the perfect fail-safe design forces the output into the same state as when the beam is interrupted. 1Emitting element 2Emitting circuit STOP Cable broken Much smaller objects can be detected.

It saves you space. Hazardous area point Conventional model 40mm beam pitch area sensor point Hazardous area mm beam pitch area sensor The sefety distance can be shorten because of the narrow beam pitch. Automatic Sensitivity Compensation series constantly maintains the optimum sensitivity according to your setting distance and the sensing condition. The sensitivity is automatically gained if the incident beam intensity decreases by dirt, dust, mist or oil on the sensing face. It also makes the sensor insusceptible to any ambient beam such as the other sensor s beam, or the glare of welding. Long Range : 7m Its sensing range is 7m long at mm beam pitch. Wide Variation There are eight types of sensors in height from 140mm ( beam ) to 1,20mm (4 beam ). The spatter-protection model is also available in each height that protects the sensing face against welding spatters by the hood. height 1,20mm 4 beam 5 beam The longest in the series contains 4 beam at 1,20mm high. 4 beam 40 beam 32 beam 24 beam 1 beam beam 140mm 334

Their lights may affect the detectability. The lockout output can be used for the monitoring purpose only. o not use it to control the machine operation directly instead of the sensing output (relay contacts). If the lockout output does not retreat into ON by power-up, the C might be out of order such as by the output relay contact welded, or the internal circuit. Replace the controller with the new C. The set of the sensor is incorporated with the automatic sensitivity compensation function. While the beam alignment is carried out, the indication and the output may delay to respend to movement of either or both sensors. From selection to installation of sensor 1etermine the hazardous area, in height and length. 2etermine the protection area with the sensor.
