Telco’s range of optical sensors are designed, developed and manufactured in Denmark and exported worldwide. The Spacepak SP 2000 series of photoelectric sensors consists of a self-contained SPT transmitter and SPR receiver which are used in through-beam mode; the SPP for diffuse proximity mode; the SPRR for retro-reflective mode; the SPPR for polarised retro-reflective mode; and the SPBS for background suppression. All are offered with sensitivity adjustment via an integral potentiometer with either cable or 1800 rotatable plug connection.
The complete series is available either as a 4 wire, NPN or PNP transistor output with 10-30 VDC supply voltage or as a 5 wire, relay output with a 12-240 V AC/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 used for disabling or enabling the transmitter power temporarily for test purposes or for multiuplexing 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. All products include a 3-year worldwide warranty.
