1. Mfiri anohyeto switch

Mpɛn pii no, wɔde saa switch yi di dwuma de siw gyinabea anaa stroke a mfiri no kankan no ano hye, sɛnea ɛbɛyɛ a mfiri a ɛretu no betumi agyina ne ho, asan akɔ akyi, ahoɔhare a ɛsakra a ɛkɔ so anaasɛ automatic reciprocating movement sɛnea gyinabea anaa stroke pɔtee bi te. Ɛyɛ adwumayɛ ti, nkitahodi nhyehyɛe ne dan. Wɔakyekyɛ mu ayɛ no tẽẽ-adeyɛ (button), rolling (rotary), micro-adeyɛ ne nkabom.

Direct-acting limit switch: adeyɛ nnyinasosɛm no te sɛ nea ɛwɔ button no mu, nsonsonoe no ne sɛ biako yɛ nsaanodwuma, na biako nso ne bamper a ɛwɔ ɔfã a ɛrekɔ no bɔ. Sɛ impact block a ɛwɔ abɔnten fã a ɛretu no so no mia bɔtn no so ma contact no tu a, sɛ ɔfã a ɛretu no fi hɔ a, contact no ankasa san sesa wɔ spring no adeyɛ ase.

Rolling limit switch: Sɛ wɔmia stop iron (collision block) a ɛwɔ afiri a ɛretu no so wɔ roller a ɛwɔ limit switch no so a, transmission poma no ne shaft a ɛkyinkyini no di akɔneaba, ma enti cam no pia impact block no, na sɛ impact block no bɔ beae pɔtee bi a, ɛpia micro movement no Switch no yɛ adwuma ntɛmntɛm. Sɛ woyi dade a wɔde gyina roller no so no fi hɔ a, spring a ɛsan ba no san de akwantuo switch no si hɔ. Eyi yɛ ntwahonan biako automatic recovery anohyeto switch. Na akwantu switch a ɛwɔ ntwahonan abien a ɛkyinkyini no ntumi nsan nnya bio, na sɛ ɛde ne ho to afiri a ɛretu no so sɛ ɛbɛkɔ ɔkwan a ɛne no bɔ abira so a, dade a wɔde siw ano no bɔ rola foforo mu ma ɛsan de ba.

Micro switch yɛ snap switch a nhyɛso na ɛyɛ adwuma. Ne nnyinasosɛm a ɛyɛ adwuma ne sɛ abɔnten mfiri tumi no nam ade a ɛde nkrasɛm no so yɛ adwuma wɔ adeyɛ demmire no so (mia pin, bɔtn, lever, roller, ne nea ɛkeka ho), na bere a wɔaboaboa ahoɔden no ano akɔ beae a ɛho hia no akyi no, adeyɛ bi a ɛba ntɛm ara ba, sɛnea ɛbɛyɛ a nkitahodi a ɛkɔ so wɔ adeyɛ demmire no awiei no bɛka asɛm no ne nkitahodi a ɛyɛ pintinn no mu ntɛmntɛm anaasɛ wɔatwa mu. Sɛ woyi tumi a ɛwɔ ade a ɛde nkrasɛm no so no fi hɔ a, adeyɛ demmire no ma tumi a ɛdannan kɔ akyi ba, na sɛ ade a ɛde nkrasɛm no akyi a ɛbɔ no du baabi a ɛho hia a demmire no yɛ ade no a, wɔwie adeyɛ a ɛdannan no ntɛm ara. Micro switch no contact distance sua, action stroke no yɛ tiaa, pressing force no sua, na on-off no yɛ ntɛmntɛm. Ahoɔhare a ne contact a ɛrekɔ no yɛ adwuma no ne ahoɔhare a ɛwɔ transmission element no mu no nni hwee yɛ. Mfitiaseɛ type of micro switch ne push pin type, a wobetumi anya afi button tiawa stroke type, button kɛse stroke type, button extra kɛse stroke type, roller button type, reed roller type, lever roller type, tiawa abasa type, tenten abasa type etc.

Mfiridwuma valve anohyeto switch no taa gye micro switch a passive contact no tom, na wobetumi akyekyɛ switch form no mu ayɛ no: dua biako a wɔtow mmɔho abien SPDT, dua biako a wɔtow biako SPST, dua abien a wɔtow DPDT.

2. Proximity anohyeto switch

Proximity switch, a wɔsan frɛ no non-contact akwantu switch, ntumi nsi akwantu switch ananmu nko ne contact to wie akwantuo control na anohyeto ahobanbɔ, na mmom nso de di dwuma ma high counting, ahoɔhare susuw, nsu level control, ɔfã kɛse detection, automatic nkitahodi a processing akwan twɛn. Esiane sɛ ɛwɔ su ahorow a ɛnyɛ nkitahodi trigger, ntɛmntɛm adeyɛ ahoɔhare, adeyɛ wɔ detection akwansin ahorow mu, stable ne pulse-free sɛnkyerɛnne, stable na ahotoso adwuma, nkwa tenten, high repeat positioning pɛpɛɛpɛ ne adaptability to hard work environments, ne nea ɛkeka ho, enti Wɔde di dwuma kɛse wɔ mfiridwuma mu nneɛma te sɛ mfiri nnwinnade, ntama, tintim, ne plastics.

Wɔakyekyɛ proximity switches mu sɛnea adwuma nnyinasosɛm no te: titiriw no high-frequency oscillation type, Hall type, ultrasonic type, capacitive type, differential coil type, daa magnet type, ne nea ɛkeka ho Permanent magnet type: Ɛde suction tumi a ɛwɔ daa magnet no mu di dwuma de ka reed switch no ma ɛde sɛnkyerɛnne no fi adi.

Differential coil type: Ɛde eddy current ne nsakrae a ɛba magnetic field a ɛba bere a ade a wɔahu no bɛn no di dwuma, na ɛnam nsonsonoe a ɛda detection coil ne comparison coil no ntam so na ɛyɛ adwuma. Capacitive proximity switch: Ɛyɛ capacitive oscillator ne ɛlɛtrɔnik circuit titiriw. Ne capacitance no wɔ sensing interface no so. Sɛ ade bi bɛn a, ɛbɛwosow esiane ne coupling capacitance bo a ɛsakra nti, ɛnam so ma wosow anaasɛ ɛbɛma wosow no agyae ma ayɛ output signal. nsakrae kɛse rekɔ so.

Sɛ magnetic pole S no hwɛ proximity switch no a, proximity switch no output no wɔ positive jump, na output no kɔ soro. Sɛ magnetic pole N no hwɛ proximity switch no a, nea efi mu ba no sua. tipɛn.

Ultrasonic proximity switch: Ɛyɛ titiriw ne piezoelectric ceramic sensors, ɛlɛtrɔnik mfiri a wɔde fa ultrasonic asorɔkye na wogye asorɔkye a ɛdannan, ne program-controlled bridge switches a wɔde sesa detection range. Ɛfata sɛ wohu nneɛma a wontumi nka anaasɛ wontumi nka ho. Nneɛma te sɛ nnyigyei, anyinam ahoɔden, ne hann nhaw ne tumidi dwumadi. Detection botae no betumi ayɛ ade a ɛwɔ solid, nsu anaa powder tebea mu, bere tenten a ebetumi ada ultrasonic asorɔkye adi.

High-frequency oscillation proximity switch: Ɛyɛ dadeɛ na ɛkanyan, titire no ɛyɛ afã mmiɛnsa: high-frequency oscillator, integrated circuit anaa transistor amplifier ne output device. N’adwuma nnyinasosɛm ne sɛ: coil a oscillator no ma magnetic field a ɛsesa wɔ active surface of the switch , sɛ dade ade bi bɛn active surface no a, eddy current a ɛba wɔ dade ade no mu no bɛtwe oscillator no ahoɔden, na ama oscillator no agyae wosow. Wɔdan nsɛnkyerɛnne abien a ɛkyerɛ sɛ wosow ne wosow gyina oscillator no mu no ma ɛbɛyɛ binary switching signals bere a wɔayɛ no sɛnea wɔayɛ no na wɔama ayɛ kɛse akyi, na switching control signals no fi adi.

Magnetic induction valve anohyeto switch no taa gye electromagnetic induction proximity switch a passive contact no tom, na wobetumi akyekyɛ switch kwan no mu ayɛ no: dua biako a wɔtow mmɔho abien SPDT, dua biako a wɔtow biako SPSr, nanso DPDT a ɛtow abien abien nni hɔ. Wɔtaa kyekyɛ magnetic induction no mu ayɛ no 2-wire a ɛtaa bue anaasɛ ɛtaa to mu, na 3-wire no te sɛ single-pole double-throw SPDT, a ɛntaa bue na ɛtaa to mu.
