SICK Background Suppression Photoelectric Sensor, Block Sensor, 20 mm → 950 mm, Relay, IP67

Sick G10 Series Photoelectric Sensor, IP67, 10ms Response Time - GTB10-R3812

This photoelectric sensor detects objects using background suppression and is intended for industrial automation tasks where reliable presence or absence detection is required. It operates with visible red LED illumination and is supplied with a mounting bracket, making it suitable for panel installation in electrical and mechanical systems that require isolated relay switching.

Features & Benefits

• 24V to 240V AC/DC supply accommodates varied plant voltages
  Relay SPDT output allows electrically isolated switching up to 3A
  Response time 10ms supports moderate-speed detection cycles
  IP67 protection permits use in dust-tight and water-exposed zones
  Potentiometer adjustment with five turns enables precise range setting
  LED indicators provide status of power and received light beam

Applications

• Suitable for material handling presence detection on conveyor lines
  Ideal for pick-and-place systems requiring background suppression
  Used for door or gate monitoring where isolated relay switching is needed
  Can be used for object counting on packaging machinery with variable reflectance
  Suitable for panel-mounted sensing in OEM control cabinets

What cable connection is provided for installation?

The unit is fitted with a 2m, five-core PVC cable terminated for direct wiring to control circuits.

How does the sensor perform with different surface reflectances?

The sensing range varies by reflectance
maximum reach is 950mm on 90% reflective targets with a defined light spot profile.

What environmental temperatures can the device withstand during operation?

It operates between −30°C and +60°C and may be stored between −40°C and +70°C.

Which materials are used for the housing and what benefit do they offer?

The enclosure combines ABS, polymethyl methacrylate and PVC components to balance optical clarity, durability and electrical insulation.

What switching endurance can be expected under rated load?

The relay is specified for a minimum of 100,000 switching cycles at 3A load.
