SA1E series – sub-miniature photo-electric sensor

Designed to function consistently over time and tolerate harsh industrial environments, SA1E photoelectric sensors are assembled using precise robotic technology to produce a reliable, accurate and durable product. Available in seven different optical functions, there’s an SA1E sensor for every application.

Competitively priced, these sensors are also easy to install and incorporate numerous features in a compact housing. A choice of NPN or PNP outputs are available, as well as Dark ON or Light ON operation modes, and all SA1E sensors are IP67 rated, UL/c-UL listed and CE marked.

Laser models
The New SA1E-L Class 1 laser models utilise a visible, red laser perfect for:
• Detection of fast moving objects
• Detection of tiny objects
• Detection through narrow or limited space
• Detection at a long distance


  • Seven optical functions: background suppression, through-beam, polarised retro-reflective, diffuse-reflective, small-beam reflective, convergent reflective and accurate and reliable detection of transparent objects
  • Fast response time
  • Miniature housing design with cable or M8 connector options
  • Class 1 Laser models available in through-beam, polarized retro-reflective and background suppression
  • 24VDC
  • IP67waterproof protection

SA1U series – Heavy Duty, universal photo-electric sensor

When your application requires a sensor with reliable long distance sensing in unforgiving environments, look no further than the heavy duty SA1U photoelectric sensors from IDEC. These high-quality photoelectric sensors are offered in four sensing modes: through-beam, background suppression, diffuse and polarised retro reflective. Long distance sensing ranges as far as 50 meters with through-beam models and as close as 1 meter with diffuse models. They also support 12-240V DC and 24-240V AC, a much wider range of power at a great low price compared to most competitor sensors.

SA1U sensors utilise a spring up screw terminal making wiring easy. You can use almost any conductors and no special cables or connectors (M8 or M12) are required. These switches are assembled in a fully automated robotic process and are UL/c-UL listed, CE marked and IP67 rated, making them ideal for use in wet environments such as bottling and food processing industries. SA1U is also perfect for direct sunlight applications.


  • Four optical functions: background suppression, through-beam, polarised retro-reflective, diffuse- reflective
  • Universal voltage – Supports 12-240VDC and 24-240VAC
  • Long sensing distance (up to 50m for through-beam)
  • Time delay functions (One shot, ON, OFF delay)
  • 3 amp Relay Contacts (NO/NC)
  • Spring up screw terminal for easy wiring
  • IP67 waterproof protection
