Ultrasonic Proximity Sensor & Module (HG -P40 Series)
Ultrasonic Proximity Sensor & Module Model : HG-P40 Series ▣ Features • Multi functional transceiver model • Two types of transmit modes (Free Run / External Trigger) • Power Supply (Low : 5V / High : 6~16V) • 4 different output signals (simultaneously) − Real time received and amplified ultrasonic wave HG-P40C (Conventional) Approx.
Ultrasonic Proximity Sensor & Module Model : HG-P40 Series ▣ Description • Using only a single transceiver sensor unit for transmit and receive signals. • Convenient for distance measuring and object detection. • Two types of transmit mode for convenience.
Ultrasonic Proximity Sensor & Module Model : HG-P40 Series ▣ Part Name 4 5 1 6 2 7 8 10 3 9 ① Ultrasonic sensor unit : Ø16 Open type sensor has conventional directivities(appox. 65~75˚). ② Power selection PAD(J2) : Low(5V) – with soldering, High(6~16V) – without soldering(at this condition, more than 6.5V is recommanded).
Ultrasonic Proximity Sensor & Module Model : HG-P40 Series ▣ Timing Chart ① 3~5 V ② 5~15 V • Trigger Pulse : generated internally or externally • Range measuring : 10~30 per second is recommended • Normal use : 10 per second is recommended • Ultrasonic burst signal from Trigger Pulse • The vibration and amplified waveform according to transmitting and receiving of ultrasonic signal. ③ 5V ④ • Masking signal(Internal) to remove the first received internal crosstalk signal.
Ultrasonic Proximity Sensor & Module Model : HG-P40 Series ▣ The principle of perceiving proximal object within 40cm range. ※ There will be no quantitative distance value. This is only for determining the object existence and non-existence Echo3 Housing OBJECT ※ Surface of the housing may cause different result. Echo1 5V ① Echo1 ② Masked (Removed) Echo2 Echo2 • Masking signal(Internal) to remove the first received interrupt signal.
Ultrasonic Proximity Sensor & Module Model : HG-P40 Series ▣ Input / Output Terminal Configuration Output Terminal Input Terminal e a f b g c d ▣ Terminal Configuration ⓐ Output signal within the preset(distance) range (#⑩ wave from the Timing Chart(Page 5)) (Yellow) ⓑ External Trigger / Monitor Terminal (Orange) − Signal input terminal for External Trigger Mode (0.5~1mS TTL recommended) − Monitor terminal for Free Run Mode to confirm the Trigger Timing. Internal trigger is generated.
