Takex America (Pulnix) PB-IN100AT "Anticrawl" Quad Photolectric Beam 300 T/R with Form C
Custom orders usually ship in 1-2 weeks.
The PB-IN-I00AT "Anticrawl" Photoelectric Beam was designed for high security applications where attempts to crawl through a portion of the photobeam create an alarm event instead of no alarm. Transmitters project double modulated beams that differ in pulse pattern from upper and lower parts.
Through CPU processing, the upper receiver selects the beam from the upper transmitter and the lower receiver selects the beam from the lower transmitter, allowing for an AND-gated or an OR-gated system.FOUR FREQUENCY SELECTION
4 separate choices of frequency avoids cross-talk in stacked or long linear installations. DUAL RESPONSE TIME SYSTEM
Two individual response times are provided for separate adjustment of AND/OR gates. This enables detection of intruders, but minimizes false alarms. BEAM TRANSMISSION STRENGTH SELECTION
2 levels of beam transmission strength which can be set to suit the protection distance. AUTO-GAIN LOCK
Optimal sensitivity gain is automatically set at any coverage distance up to the maximum protection distance. Auto-Gain lock is easily confirmed by sound check. EASY BEAM ALIGNMENT
An alignment tone enables quick set-up. The tone becomes maximum at peak of beam level. With the beam selector, the upper and lower beam alignment can be adjusted without using a shading plate. PROTECTION AGAINST FROST/DEW
A special hood is attached on sensor cover, so that beam protection continues without interruption
