Idle Current Io
The sensor electronic of 3 and 4 wired sensors demands a minimum current flow to ensure a proper internal function, also if no load is connected to the sensor.
PULSOTRONIC Inclination Sensors measure angles in all 3 axis: X - Y- Z.
The inclination value in degree (°) describes the angel from zero degree (0° to earth gravity field) in only ONE direction. Our sensors detect this angle in booth directions, p.e. 90° means angle from -90° to +90°.
Inductive Proximity Switch
The principle of function is based on the interaction of metallic objects with the electro magnetic field of the sensor. In the metallic damping material, eddy currents are induced which take energy out of the field and therefore reduce the height of the oscillation amplitude. This reaction is analysed within the sensor.
Infrared LightIR stands for ”infrared”. This electromagnetic radiation (approx. 780 - 15000 nm) has a longer wavelength range than visible light (approx. 380 - 780 nm). It is also possible to use diodes in other wavelength ranges (red, green light) but usually, this reduces the sensing distances which can be achieved. As a result of the high absorption, IR light cannot be used for plastic fibre light conductors where red light is used instead. Because of the fact that common polarising filters cannot be used in the IR range, red light is used for reflecting light barriers, too.
For inductive loads that are working with AC voltage (like contactors etc.) the initial power consumption (initial load) of the magnetic coil is essentially higher than the power consumption while holding (continuous load). For small contactors with continuous load of several VA, the ratio between initial and continuous load is ca. 2 to 4, for bigger contactors with continuous loads of 100 VA, the ratio is ca. 20. If contactors are connected with AC sensors, the maximum permissible initial load for the sensor is determined out of the values of the rated operating voltage and the information "short-time current" of the data sheet.
Initial torques are indicated in Newton metre (Nm). 1 Nm means: on a hand gear of 1m works a force of 1 Nm. The value of the initial torque describes the maximum force that should be used for tightening the fixing elements against the sensor housing. If the maximum defined torque is exceeded through forcible overwind of the fixing nuts, the housing of the sensor can suffer irreparable damage up to tearing of the housing.
