The SP 2000 series consists of a self-contained transmitter SPT and receiver SPR, which are to be used in through-beam mode, an SPP for diffuse proximity, SPRR for retro-reflective, SPPR for polarised retroreflective and SPBS for background suppression. All are offered with sensitivity adjustment via integral potentiometer with either cable or rotatable plug connection.
The complete series is available either as a 4 wire, NPN/PNP transistor output with 10-30 VDC supply voltage or as a 5 wire, relay output with a 12-240 VAC/DC supply voltage, both offering switch selectable light or dark function and potentiometer adjustable 0-10 sec on/off time delay.
The test input in the 10-30 VDC, SPT is intended to be used for disabling or enabling the transmitter power temporarily for test purposes or for multiplexing applications. The DC series is protected against reverse polarity of power supplies, test input and output signals. The output is protected against short circuit and inductive loads.
