Model : HG-P40 Series

Ultrasonic Proximity Sensor & Module

▣ Part Name

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).

③ Proximity detection LED : When object enters the preset range, red light is on

and 10mA output signal is generated

④ Output Terminal : three different output is generated simultaneously.(Refer to

Page 2 and 6)

⑤ Receiver sensitivity adjusting

VR : Adjusting gain value of pre-amplifier from

range of 0 to 4,000x.(Default factory option: 2,000X)

⑥ ASIC Chip : 48pin Chip with many functions. (Hagisonic Product)

⑦ Distance range adjusting VR : 0.5 to 4.5m range.

⑧ Ultrasonic frequency adjusting : Factory tuned for unit for the best

performance(Do not adjust this!)

⑨ Input Terminal : Power, External Trigger input and proximity output signal(10mA

current) terminal(Refer to Page 2 and 6)

⑩ Transmit Mode selection PAD(J1) :

− Free Run Mode : With soldering; approx. 10 to 15 Burst per second is generated.

(factory option : Soldered)

− External Trigger Mode : Without soldering; External TTL level Pulse is needed for

transmit.(1~100 per second available, but 10~30 per second

recommanded) (Pulse width : 0.5~1mS recommended)
