Rotary sensors from TT Electronics work in harsh, critical environments
Three rotary sensors from TT Electronics are designed for critical applications, where repair costs would be high in the case of failure.
The three PHS series of hollow shaft, single turn rotary position sensors, the PHS04, PHS07 and PHS11, are precise, robust and reliable, claims TT Electronics.
The PHS04, PHS07 and PHS11 convert angular mechanical position, or the motion of a shaft, or axle to an analogue, or digital electrical signal, and are designed for applications that require adjustments to control variable outputs such as position, speed or volume, says TT Electronics.
Characteristics shared by the three series are their dust proof construction and stable output characteristics in harsh environments. The rotational angle is 360 degrees and operating temperature ranges of up to -40 to +120 degree C are tolerated, in the case of the PHS11.
The TT Electronics’ PHS rotational sensors can be hand- or wave-soldered and feature characteristics of greater than a million cycles, or at least 300,000 in the case of the PHS04 with a 500,000 cycles option available. They are small; the PHS11 boasts a thin height of 2.2mm and the PHS04 measures 4.0 x 5.0mm.
Responding to customers’ requests and applications, TT Electronics is able to customise the sensors’ shaft hole diameters, for the PH07 and PHS11 ranges. Rotor types can also be customised from D to H types, together with electrical output angles and linearity tolerances.
Applications for the PHS series are the industrial, medical and transportation markets, for example in robot joint angle control, game controllers, motor drive units, 3D printers, intelligent surveillance camera positioning, rotary angle sensors, electric motor-driven bicycles, heating, ventilation and air conditioning (HAVC) sensors, patient monitoring systems, medical diagnostic devices, dental chair positions, car audio and shift-by-wire gearshift systems.
TT Electronics’ PHS04 and PHS07 are supplied in trays or boxes and it slim PHS11 sensors are supplied in tape and reel form.
