112-1-A-5-2D Pickering Electronics, 112-1-A-5-2D Datasheet - Page 2

• Manufacturer Part Number: 112-1-A-5-2D
• Description: Single-in-line Reed Relays
• Manufacturer: Pickering Electronics

Series 112 switch ratings
The contact ratings for each switch type are shown below:
Switch number 2 is suitable for low level or "cold" switching applications. It is
also a good general purpose "hot" switch as long as the maximum switching
current specifi cation is observed. There is no Switch number 1 available in this
range at present.
When an internal diode is required, the suffi x D is added to the part number as
shown in the table. If a diode is not required, the D suffi x should be omitted.

(initial)
The Following actual size example illustrates the relative packing densities of
standard 0.2 x 0.8 inch SIL relays compared with Pickering Series 108, 109,
and 112 reed relays when packed into an area of 1.2 x 2.4 inches.
Important: Pickering SIL relays feature mu-metal magnetic screens,
unscreened relays are unsuitable for dense packing in this way.
