User manual

 Complementary light and dark operate outputs (selectable light or dark operate on background
suppression models).
 Two LED indicators provide status of power, output, unstable operation and short-circuit protection.
 Improved 1 ms response time on most models.
 Extended range high-speed models with a 0.5 ms response time.
 Patented ASIC design offers linear sensitivity adjustment, stabilty
indication and excellent noise immunity.
 Flat lens reduces dust collection and improves ease of cleaning.
 Visible red LED light source on polarized retroreflective models.
 Input to disable light source on transmitted beam emitter for testing and scanning purposes.

 Suffix -D4 denotes 4-pin DC micro connection type. For 2 m cable without QD replace suffix -D4 with -A2 (e.g.
42CA-P2MPB-A2). All models shown in selection table above are PNP output versions. Replace the eighth digit
(P) with N for NPN (example: 42CA-U2MNB-D4 is NPN).
