The HSM14F Hall-effect single-turn encoder from MEGATRON has an extremely compact design, with a housing depth of just 6.2 mm.

Other outstanding features of the encoder include its high resolution and long bearing life. With the optional redundant electronics, the encoder is also suitable for use in applications with increased requirements for operational reliability.

The HSM14F has a very small housing depth and diameter of just 14 mm. Its compact dimensions make it the ideal angle sensor for all applications with limited installation space. The HSM14F offers a resolution of 12 bits (4096 steps) and an electrically effective angle of rotation of 360°. Angles of 90°, 180° and 270° as well as customized values are also possible.

The HSM14F Hall-effect encoder is flange-mounted. With a wide operating temperature range of -40 to +105 °C and IP65 protection, the encoder is suitable for applications with increased environmental requirements. The integral sleeve bearing has a life of 100 million revolutions and the maximum operating speed is 400 rpm.

MEGATRON also modifies the HSM14F for series production according to customer requirements. For example, PWM outputs, customized output signals, different shaft geometries, shaft flattening or cable assemblies are possible.

MEGATRON also recently released the SPF and SPFH optical incremental encoders, which offer a wide range of resolutions while requiring the smallest possible installation space. Available in solid or hollow shaft versions, the encoders’ extremely compact design makes them the ideal solution for demanding applications. The ball-bearing versions of the SPF offer a very long service life, while the sleeve-bearing models are ideal for manual control applications.

The micro-optical encoders have a housing diameter of only 16 mm and a housing depth of only 9.83 mm (SPF) for solid shaft or 8.92 mm (SPFH) for hollow shaft. This makes the encoders, with resolutions from 250 to 4096 pulses per revolution, ideal for use in medical, metrology, instrumentation, and robotics applications where space is often at a premium.

With a solid shaft, the SPF can be fitted with ball bearings for maximum service life or sleeve bearings, depending on the application. The latter offers a choice of shaft torques that provide a pleasant tactile feel when used for manual operation. The wide choice of shaft diameters — 3.175 mm, 6 mm and 6.35 mm — also allows the SPF to be used in applications often reserved for potentiometers.

The hollow shaft SPFH uses the shaft of the application and allows a maximum operating speed of 48,000 rpm depending on the number of pulses. It is supplied as a kit encoder and uses an innovative clip-on encoder disc that can accommodate shaft diameters of 1.5 mm or 2 mm.

Both encoders are electrically connected to the application via a 5-pin connector with 0.8 mm pitch. They provide a reliable TTL signal in the form of A, B and Z (index) signals.
