Contrinex Standard photoelectric sensors
Contrinex Standard photoelectric sensors are ideal for general position- and presence-detection in almost any industry. Available in diffuse, reflex, through-beam and background-suppression (C23, M18) variants, their exceptional accuracy, reliability and affordability make them ideal for general position- and presence-sensing in almost any industry.
The Standard range offers an excellent choice of cubic sizes: 0507 (5 × 7 × 40 mm), C12 (13 × 21 × 7 mm), C23 (20 × 30 × 10 mm), 3030 (30 × 30 × 15 mm), 4040 (40 × 40 × 19 mm), 4050 (40 × 50 × 15 mm) and C55 (50 × 50 × 23 mm). Metric-threaded cylindrical sensors are also available in M12 and M18 variants, including some M18 types with ABS housings adapted for right-angle detection.
Standard C23 and metric-threaded cylindrical photoelectric sensors are compact IO-Link-enabled devices, ideal for smart factory applications. Equipped with tough ABS housings (C23, M18P) or robust metal bodies (M12M, M18M), they feature Contrinex’s exclusive ASIC technology, offering best-in-class sensing distances at highly competitive prices. Ecolab-approved versions are already a popular choice for process engineers in the food and beverage sector.
TECHNOLOGY
Diffuse
A diffuse-mode, or energetic-diffuse, photoelectric sensor is a reflective sensor, containing a transmitter and a receiver in a single housing. The sensor emits a focused light beam toward a distant target that acts as a reflector, returning part of the transmitted light to the sensor. The receiver detects the amount of light reflected by the target, triggering the sensor when the light intensity reaches a threshold value.
- Ideal for short sensing ranges and relatively easy targets
- Easy installation and alignment
- No separate reflector or receiver
Background-Suppression
Diffuse-mode photoelectric sensors with background suppression emit a focused light beam toward a distant target. Part of the beam is reflected from the target and returns to the sensor, striking a position-sensitive receiver. The receiver distinguishes between reflections from the target and reflections from background objects, only triggering the sensor when the signal reaches a value that corresponds to the preset target distance.
- Target size, color, shape and surface finish have little influence on sensing range
- Suitable for difficult targets (small, fast-moving, light background)
- No separate reflector or receiver
Reflex
A reflex, or reflective, photoelectric sensor contains a transmitter and a receiver in a single housing, and emits a pulsed, focused light beam through a polarization filter toward a distant reflector. Reflected light returns to the sensor, passing through a second filter before arriving at the receiver. When a target object interrupts the light beam, the receiver detects the reduced light intensity and triggers the sensor. Autocollimation of the light beam allows blind-zone suppression.
- Ideal for moderate sensing ranges
- Wiring required for just one emitter/receiver unit
- Separately mounted reflector
Through-beam
Contrinex through-beam photoelectric sensors are ideal for industrial applications where sensing components must be mounted some distance from the target area. Through-beam sensors utilize infrared, visible and laser light sources to detect targets, reliably and repeatably, at extended distances.
- Ideal for long sensing ranges
- Suitable for contaminated environments or highly reflective targets
- Separately mounted and wired receiver
Contrinex Miniature photoelectric sensors
The Contrinex Miniature range packs exceptional position- and presence-sensing performance into the smallest self-contained photoelectric sensors on the market. Designers have the choice of through-beam or diffuse sensors in ø4 and M5 cylindrical metal housings that offer multiple mounting methods and beam orientation. For fully embedded applications, sensors produce focused, cylindrical light beams. An IO-Link interface is also available for communication in PNP NO versions.
Types with a 5 mm x 7 mm stainless-steel housing and a narrowly focused, cylindrical light beam are suitable for vertical or horizontal mounting directly on the supporting surface. Best-in-class sensing distances of up to 90 mm allow them to be positioned at a safe distance from the target.
The C12 Series (13.5 mm x 21.8 mm x 7.7 mm) with small visible light spot thanks to red pinpoint LED offers long sensing ranges up to 2000 mm in a through-beam type and 3000 mm in a polarized reflex type. Two background suppression types are available with fixed sensing ranges up to 15 mm or 30 mm. A third type with 3-turn potentiometer (13.5 mm x 27.5 mm x 7.7 mm) reliably detects objects up to 120 mm.
