The APEM Panel Switches IMR7Z4B2UL are robust autoswitches designed for demanding industrial environments. These switches feature IP67 sealing, high current/voltage ratings up to 3A 28VDC, and a snap-action mechanism with tactile feedback. They offer exceptional reliability with 1,000,000 cycles and operate across extreme temperatures from -40°C to +85°C.
The APEM Panel Switches IMR7Z4B2UL represent a high-performance autoswitch solution engineered for industrial applications requiring durability and precision. With an IP67 rating ensuring protection against dust, water, and harsh environmental conditions, these switches deliver reliable operation in extreme settings. Their snap-action mechanism provides immediate tactile feedback and audible clicks, while maintaining a high current/voltage rating of 3A at 28VDC. The switches are designed to withstand rigorous conditions, including shock resistance of 50g over 11ms and salt spray testing, ensuring long-term performance in challenging environments.
The IMR7Z4B2UL switches support electrical functions including NC/NO contacts with a maximum current rating of 3A at 28VDC for resistive loads. Initial contact resistance is 100 mΩ max, and dielectric strength reaches 500 Vrms between terminals. Electrical life at full load is 25,000 cycles.
Engineered for extreme conditions, these switches maintain performance across a storage temperature range of -40°C to +85°C. They withstand shock resistance of 50g over 11ms and salt spray testing per IEC 512-6, test 11f, ensuring reliability in harsh industrial settings.
With a total travel of 1.7mm ±0.3mm and a long travel option of 2mm, the switches feature a snap-action mechanism that provides immediate tactile feedback and audible clicks. The switches are rated for 1,000,000 cycles and can handle torque up to 1Nm with metal nuts or 1.5Nm with plastic nuts.
Available in rectangular rocker-action caps with three sizes (10.1 x 12.5 mm, 18.65 mm, and 25.0 mm), the IMR7Z4B2UL series supports customization into custom keyboards. The flat round actuator allows for optional NO+NC marking, enhancing user interface flexibility.
