Intelligent, self-optimising entrance sensors
May 2005
Sensors & Transducers
The new compact PA01 system from Telco is designed to fit into the doorframe of automatic doors, elevators, garages, gates (up to eight metres across) - as well as the entrances to escalators and walkways. The system is based on a newly developed STF 'Signal Tracking Feature'. What this does is enable the system to automatically adjust to another position when it encounters noise or interference from another photoelectric system. This slows more systems to work near each other without interrupting each other. If the noise present on the sensor line exceeds acceptable levels, an alarm is triggered. The microprocessor-based design automatically adjusts for each application.
Features include IP67 sealing of all sensors, the smallest physical sensors, quick, snap-in mounting, STF (signal tracking feature), Range - 5 m, 8 m, microprocessor controlled for automatic adjustment - manual reset adjustment and relay or NPN/PNP output.
A single pushbutton provides the optimum gain setting, automatically compensating for dirt build-up. The system automatically re-adjusts on power up - and the system will keep on making adjustments to maintain the optimum performance.

PDS implementation on mines
Sensors & Transducers
Level 9 vehicle intervention for collision avoidance has been mandatory on South African mines since 2022, yet the effective roll-out of proximity detection systems remains slower than expected. This is not due to the technical limitations of integration but to operational readiness on site.
