Sensors & Transducers
The 8000 series consists of a self-contained transmitter (SMT) and a receiver (SMR) which are to be used in through-beam mode, an SMP for diffuse proximity, SMRR for retro reflective and an SMPF for use with fibre-optic cables. All are offered with sensitivity adjustment via integral potentiometer with either cable or plug connection.
The complete series is availble either as 3 wire, NPN or PNP transistor output with a 10-30 V d.c. supply voltage, or as 2 wire, SCR with a 20-250 V a.c. supply voltage, both offering switch selectable light or dark function. The control input in the 10-30 V d.c. SMT is intended to be used for disabling or enabling the transmitting power temporarily for test purpose or for multiplexing applications.
The DC series is protected against reverse polarity of power supplies, control input and output signals. The output is protected against short circuit and inductive loads.

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.
