Photoelectronic Sensors
Photoelectronic Sensors in Hygienic Housing
- Hygienic design without corners and edges for easy cleaning and optimal dirt and cleaning agent drainage
- Food-safe materials with FDA compliance
- Resistant to high-pressure cleaning with IP69K degree of protection
- Hermetically sealed stainless steel 316L housing with touch teach-in for absolute leak-tightness
- Laser-welded housing with captive optics
- Gap-free installation option for the highest hygiene requirements
Photoelectronic sensors can detect or count objects contactlessly using light. The high-quality hygienic housing in stainless steel 316L (1.4404/V4A) is characterized by its special round shape without dirt edges and hermetic seal. The hygiene series is available as an energetic reflex sensor, reflex sensor with background suppression, through-beam sensor and retro-reflex sensor for transparent objects. Different types of light, such as red light, infrared light or red laser light are available depending on the intended use.
Hygienically Designed Sensors in Use – Clean Outside, Intelligent Inside
Yogurt Pot Presence Check
In the production of yogurt, it is important to ensure that there is a pot in each recess of the indexing belt before applying the lids. After each production, the indexing belts are cleaned via high-pressure jets and CIP cleaning. The FDA-compliant sensors meet these hygiene requirements – thanks to their special stainless steel 316L design, all water drops run off and the lenses do not fog up.

Food Tray Detection
When portioning meat, trays must be reliably detected on conveyors with a width of just 150 mm. The belts are cleaned at regular intervals with high-pressure jets and CIP cleaning. The FDA-compliant sensors are waterproof (IP68/IP69K) and resistant to cleaning agents, so they can withstand the high hygiene requirements.

Hygienic Protective Housings for Sensor and Image Processing Solutions
- Hygienic design for easy cleaning and safe drainage of dirt and cleaning agents
- Food-safe materials with FDA compliance
- Resistant to high-pressure cleaning with IP69K degree of protection
- Corrosion-free stainless steel 316L
- Captive optics
- Hygienic design for mounting different types of sensors
The protective housings in stainless steel 316L enable hygienically designed integration of a wide range of sensors and image processing products in cleaning-intensive environments. The integrated sensors in M or P format, vision sensors,Smart Cameras and 1D/2D and barcode scanners are optimally protected against cleaning agents and high-pressure cleaning in a protective housing with IP69K degree of protection. Variants with PMMA optics for the food industry or glass optics for the pharmaceutical industry are available depending on the field of application.
The protective housing is supplemented by extensive system components for hygienically designed mounting.

Ultrasonic Sensors
采用卫生设计的超声波传感器
采用卫生设计，清洁简便，对清洁剂具有最大的耐抗性（ECOLAB）
使用符合 FDA 规范的食品级材料
由于防护等级为 IP69K，耐高压清洗机清洗
采用密封不锈钢外壳，确保绝对密封
无缝安装，满足最高卫生要求
超声波传感器能够分析被物体反射的声波。超声波传感器几乎可以识别任何物体，不受材料、聚合状态、颜色或透明度的影响，特别适用于液体液位和散料料位的检查或透明物体的识别。
由于高品质不锈钢外壳（1.4404）采用卫生型设计，该传感器适用于 要求苛刻的卫生区域。为此，传感器既可用作漫反射传感器，也可用作超声波对射传感器。
全金属超声波传感器 – 耐抗性强，用途广泛
检测输送带上的食品
绞肉机物位的测量
绞肉机用于肉末的工业加工和分份。为了能够连续灌装，必须监测粉碎的碎肉物位。为此，在进料容器上方安装一个采用不锈钢外壳的超声波测距传感器（防护等级为 IP69K）。由于采用卫生型设计，传感器本身可以耐抗高压、高达 80 °C 的高温和侵蚀性清洗剂的强力清洗。
