Omron D5B-1535 Limit Switch
Omron D5B-1535 is an M10 mechanical touch switch with a long spring wobble stick actuator for detecting light or indirect contact in compact automation equipment. The extended spring provides greater reach where the target cannot make rigid contact with a conventional plunger, while slow-action switching supports low-current control circuits. A 5 m oil-resistant cable simplifies wiring between the detection point and control system, and IP67 protection supports industrial environments exposed to moisture or oil. The D5B-1535 belongs to the D5B Series within the sensitive machine detection switch range from Omron industrial switches for compact position and contact sensing.

The Omron D5B-1535 Limit Switch uses a long spring wobble stick actuator for flexible mechanical contact detection in compact machinery. The M10 metal body supports threaded mounting, while the long spring can receive light or indirect contact from moving parts without requiring a rigid plunger-style approach. Its slow-action switching is specified for resistive microloads from 1 mA at 5 VDC to 30 mA at 30 VDC. The switch operates across a target speed range of 5 to 500 mm/s and is supplied with a 5 m oil-resistant cable, helping route the connection from the detection point to a remote control location.
Industrial protection is supported by an IP67 enclosure and an operating temperature range of -10 to 70°C with up to 95% operating humidity. Insulation resistance is 100 MΩ minimum at 250 VDC between each terminal and ground, while contact resistance is 3.1 Ω maximum. Mechanical shock resistance is specified at 1,000 m/s² minimum, with malfunction shock resistance of 300 m/s² minimum. The switch also withstands malfunction vibration from 10 to 55 Hz at 1.5 mm double amplitude. These characteristics suit sensitive contact detection around conveyors, mechanisms, and compact automated equipment.
