The Telco SpaceMaster series offers self-contained, compact high-powered, photoelectric sensors. These rugged, long-range sensors can be used in harsh environments, such as timber/forestry applications, car washes, and many other industrial applications.
See below for the technical specs of the Telco SpaceMaster 7000, 8000, and 9000 series. For additional information please contact us.

SpaceMaster™ 7000
- Operation mode and max sensing range:
- Thru-beam: 0 – 100′
- Diffuse proximity: 0 – 39″
- Retro-reflective: 0 – 10′
- Fiber: Dependent on fiber optic cable
- 18mm threaded barrel
- Stainless steel or Polycarbonate
- Cable or quick-disconnect plug connection
- Sensitivity adjustment via potentiometer
- Switch-selectable light or dark operated
- 10-30 V dc or 20-250 V ac
- 4-wire, NPN/PNP transistor output or 2-wire SCR output
The SpaceMaster™ 7000 series consist of a self-contained transmitter SMT, and a receiver SMR which are to be used in thru-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 SpaceMaster™ 7000 series is available either as 4 wire, NPN, PNP transistor output; or 4 wire ambivalent PNP/PNP output with a 10-30 V dc supply voltage, both offering switch selectable light or dark function. The SMR is available with either a 0.5 ms response time and a 7 metre range or with a 2 ms response time and a 20 metre range. The control input in the SMT is intended to be used for disabling or enabling the transmitting power temporarily for test purposes or for multiplexing applications.
The complete series is protected against reverse polarity of power supplies, control input and output signals. Output is protected against short circuit and inductive loads.
All products include a 3-year worldwide warranty.

All are offered with sensitivity adjustment via integral potentiometer with either cable or plug connection.
The complete SpaceMaster™ 8000 series is available either as 3 wire, NPN or PNP transistor output with a 10-30 V dc supply voltage; or as 2 wire, SCR output with a 20-250 V ac supply voltage both offering switch selectable light or dark function. The control input in the 10-30 V dc SMT is intended to be used for disabling or enabling the transmitting power temporarily for test purposes or for multiplexing applications.
The dc series is protected against reverse polarity of power supplies, control input and output signals. Output is protected against short circuit and inductive loads.
All products include a 3-year worldwide warranty.

SpaceMaster™ 9000
- Operation mode and max sensing range:
- Thru-beam: 0 – 230′
- 18mm threaded barrel
- Stainless steel or Polycarbonate
- Cable or quick-disconnect plug connection
- Sensitivity adjustment via control input
- Power and output indicators
- 10-30 V dc
- 5-wire, NPN or PNP transistor output, or solid-state relay
- Up to 4 unique frequencies to avoid cross-talk — wire-selectable
- UL Class II Division 2 HazLoc models available
The SpaceMaster™ 9000 series consists of a high-power self-contained transmitter SMT, and receiver SMR, which are to be used in thru-beam mode. The complete series is available in stainless steel or plastic housing with either cable or plug connection.
The complete series is available with a 10-30 V dc supply voltage with a 5-wire, NPN or PNP transistor output with a choice between light or dark function. The control input in the SMT may be used for either disabling or enabling the transmitting power temporarily for test purposes, multiplexing applications or as gradual regulation of the transmitting power level.
The Space Master™ 9000 series features cross talk elimination which enables up to 4 individual sensor pairs to operate independently, configurable with the use of a 2-wire channel selection in the SMT and SMR, ensuring that optical cross talk interference between the channels is prevented.
Both the transmitter and receiver are protected against reverse polarity of power supplies, control input and output signals. Output is also protected against short circuit and inductive loads.
