The Omron D4B-2A15N Limit Switch uses a roller lever with a stainless-steel roller, a 2NC contact form, and slow-action operation. The conduit specification is G1/2 (PF1/2). Its operating speed is 1 mm/s to 0.5 m/s. Operation frequency is specified as 120 operations/minute mechanical and 30 operations/minute electrical. Electrical characteristics include 600 V rated insulation voltage, 50/60 Hz frequency, 25 mΩ max. contact resistance, and 100 MΩ min. insulation resistance. The stainless-steel roller is part of the actuator description and should be read together with the slow-action mechanism and 2NC contacts. The 2NC contact arrangement and stainless-steel roller lever are paired with slow-action operation in this exact configuration.
The D4B-2A15N is rated IP67 and is specified for -40 to 80°C operation with no icing and humidity of 95% max. Malfunction vibration is 10 to 55 Hz at 0.75 mm single amplitude. Shock specifications are 1,000 m/s² min. for destruction and 300 m/s² min. for malfunction. These specifications describe the model through actuator, 2NC contact form, slow-action mechanism, G1/2 conduit, operating speed, operation frequency, resistance, voltage, temperature, humidity, vibration, shock, and IP67 protection. For a D4B-N Series model with an adjustable roller lever, 1NC/1NO contacts, and snap-action operation, see the D4B-2116N.
