Performance
   Spanning Distance       The spanning distance is how far the transmitter and receiver can be separated and properly function.  The transmitter and receiver must be able to function reliably within this minimum to maximum range of separation. Using mirrors reduces the operating range up to 25% per mirror. (Example: 6 inches to18 feet.) 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
   Protection Height       The dimension of the active sensing field (correlates to the number of beams required). 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Sensitivity or Resolution       The smallest sized object that will be positively detected by the light curtain. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Response Time       Maximum time between actuation of sensing function and the output relays. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Operating Temperature       This is the full required range of ambient operating temperature. 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
   Basic Object Detection Size      Finger and Hand detection is necessary when the operator is a short distance away from the hazardous zone. Body (or arm detection) is suitable for perimeter guarding.
   Your choices are...         
   Finger       Detect objects the size of a finger. 
   Hand       Detect objects the size of a hand. 
   Body       Detect objects the size of a body. 
   Search Logic:      Products with the selected attribute will be returned as matches. Leaving or selecting "No Preference" will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Safety Category Type       
   Your choices are...         
   Type 2       Runs a self-check when it is turned on or reset. The safety function shall be checked at machine start up and periodically by the machine control system. If a fault is detected, safe status shall be initiated or if that is not possible, a warning shall be given. The occurrence of a fault between checking functions can lead to a loss of the safety function between checking intervals. 
   Type 3       More than one component must fail before it loses functionality. A single fault in any of the system parts does not lead to a loss of the safety function. Some but not all faults will be detected. An accumulation of undetected faults can lead to a loss of the safety function. 
   Type 4       Continuously self-check and will detect any loss of function immediately. A single fault does not lead to a loss of the safety function. The faults will be detected in time to prevent the loss of the safety function. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Physical Specifications
   Controller       
   Your choices are...         
   Integral       Most light curtains require an external controller for programming and status. This type would not need one because it the controller is integral with the transmitter and receiver. 
   External       Most light curtains require an external controller for programming and status. This type comes with the required external controller. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Multi-tasking Controller       Controller monitors and controls more than one pair of light curtains. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Mounting       
   Your choices are...         
   Brackets         
   DIN Rail         
   Floor         
   Other         
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Features       
   Your choices are...         
   Blanking or Banking       Disables one or more fixed locations within the sensing field. The safety light curtain can be programmed so that a variable number of light beams are 'blanked' or 'masked' to allow an object to extend through the field without affecting the machinery's operation. 
   Explosion Proof Enclosure         
   Floating Beam       Allows the disabling of beams at any location in the sensing field. The safety light curtain can be programmed to produce an intentionally disabled light beam that can move up and down ("float") in order to allow the feeding of an object through the curtain without causing a trip or latch condition. 
   Integral Fault or Equipment Status LCD       Transmitter or Receiver has Integral LCD for fault or equipment status. 
   Integral Alignment Status LEDs       Transmitter or Receiver has Integral LED's for light beam alignment status during initial equipment setup. 
   Latching Safety Relays (Guard Mode)       Once the sensing field of the curtain has been penetrated and a stop signal sent to the guarded machine, light curtain will not remove the stop signal until the controls are manually reset outside the protected area. Causes a Lockout Condition. This requires a manual reset after each penetration into the guarded zone. 
   Multiple Openings Protection       Light curtain can be configured to protect more than one opening (whole cell protection). Light curtain used for guarding machinery with access to the hazardous zone from more than one side or for perimeter guarding. 
   Muting       Muting is the temporary, automatically controlled, deactivation of a safeguarding device during the non-hazardous portion of the machine cycle. Allows complete bypass or disabling of the sensing filed or stop signal to the machine during the non-hazardous portion of the cycle. 
   Self-checking Circuitry         
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
