Acceleration sensors detect vibrations, seismic activities, inclinations in static systems and linear acceleration at machines, buildings and moveable goods. On the basis of micro-electronic systems (MEMS), the product range covers sensors with analogue power or voltage output, direct BUS-connection or adjustable switching shafts.
Acoustic sensors detect defined interference and switching noises on machines, tools and systems. With a temperatur range of up to 85°C, a degree of protection IP67 and an adjustable switching threshold the sensor is also qualified for industrial outdoor applications.
The housing area by which alternating field, light beam, sound and ultrasonic sound enters in the air , is called active surface. This area is essentially defined through the corresponding geometry of the used active elements like pot cores, electrodes, sound converters or optical components.
The active switching zone is the area above the active surface where the sensor reacts to the approximation of damping material. This means that it changes its switching status.
Alternating light is the light with a periodically changing radiated power. Therefore it is necessary to have information about the light frequency and the waveform if applicable (for example infrared, pulsing).
Alternating light operation is the operation where the proportion of the alternating light of the light flow within the light receiver is evaluated.
(also: Extraneous Light) The ambient light is the light that strikes the receiver of an optical sensor which does NOT come from the transmitter. Pulsotronic achieves the compensation of ambient light through the use of corresponding filter modules. The degree of insensitivity against ambient or extraneous light is an important quality characteristic for optical sensors.
(also: Operating Temperature Ta) The proximity switch does work properly within this temperature range.
Sensors that have an analogue output, generate a linear output signal (power and/or voltage). This signal changes proportionally to the distance of the measuring object. There are available analogue outputs with downward characteristic curve (highest initial value at longest distance) as well as analogue outputs with increasing characteristic curve (lowest initial value at longest distance). The aim of the use of analogue sensors is, to measure distances and processes of motion.
Sensors with non-equivalent output (antivalent / changeover) are offering normally open (NO) as well as normally closed (NC) switching functions at the corresponding connections. To use them, you need 4-wired connection cables or clamps.

Apertures are mechanic parts that limit the beam space.
Side by side assembly of several standard sensors leads to a mutual influence of the alternating fields. Because of this, the operator has to take care of installation conditions and minimum distances (see also: Flush mounting/ Non-flush mounting). For specific applications, Pulsotronic offers sensors which can be assembled parallel. In these cases, the mutual influence is eleminated by special adjustment of the alternating fields.
The assured switching distance Sa indicates the scope in which a proximity switch can be used properly within a defined voltage and temperature range: 0 ≤ Sa ≤ 0,81 Sn
Reflection principle where the light beam that strikes the reflector is reflected in parallel to itself (internal).
At axial damping, the standard calibrating plate is conducted to the axis of the active surface of the sensor. Additionally, at radial damping the situation of the switching point is influenced through the radial offset of the standard calibrating plate.
