Wide switching voltage range: 250 VAC / 220 VDC max

Fast operate and release times: 10 ms / 5 ms

Broad temperature range: -40°C to +70°C

Panasonic DS series reliability

Key Advantages

Latching design saves energy by holding position without coil power

4PDT reduces relay count and board space for complex signal paths

Sealed body improves durability in harsh and high-humidity environments

Stable performance for low-level signal integrity and repeatable switching

Simple assembly and serviceability with through-hole pins

Backed by Panasonic quality and Y-IC’s dependable distribution and support

Packaging

Type: Tube for safe handling and automated loading

Material: Molded plastic housing, fully sealed construction; tin-plated PC pins

Size: Compact, DIP-style footprint optimized for dense layouts; refer to the datasheet for exact dimensions, pad layout, and drilling patterns

Pin configuration: 4PDT contact matrix with PC pin terminations; dual-coil latching pins; standard DS series pinout; consult the datasheet for precise pin numbering and coil polarity

Thermal characteristics: Operating -40°C to +70°C; sealed case resists flux and wash; follow Panasonic soldering temperature profiles to avoid thermal stress

Electrical properties: 48 VDC coil, 7.5 mA coil current, 6.4 kΩ coil resistance, 33.6 VDC must operate voltage; 2 A contact rating; 250 VAC / 220 VDC max switching; 10 ms operate, 5 ms release; Ag/Au contact materials

Lifecycle

Status: Active and in production based on current industry data; not nearing discontinuation
