The Omron EE-SX1350 brings the range of surface mount transmissive PMS from Omron to four sizes, with 2mm, 3mm, 4mm and now 5mm slot width. The PMS has a high resolution, with a 0.5mm detector aperture.
All these devices can be re-flow soldered – allowing them to be assembled to the board in a single step along with other standard components. The surface mounting EE-SX1350 is also 65% smaller than the existing terminal style with overall dimensions of just 8.8mm × 4mm × 9mm.
The EE-SX1350 is offered with a choice of photo-transistor outputs. Omron is planning to release a 5mm slot width PMS with photo-IC outputs, known as the EE-SX3350.
In photo-IC form, the device gives a sharply defined and stable ON / OFF output, with impressive levels of accuracy and repeatability. The output is also much less affected by noise especially on the input channel. It gives the highest output current, so that it can be directly interfaced with relays and PLCs as well as fast operation, with switching speeds of micro-seconds. The photo-transistor version is lower cost.
Omron is now able to offer a range of 40 transmissive PMS devices, with connector, terminal and wire terminations as well as the SMD styles.
