Quick cross-shop: E3SLS3PWM5J03M
Same series, same PNP output and 1 ms response, but the XB4 carries IP67 and reaches 100 mm; the 5J03M is IP40 and maxes at 60 mm. The XB4 supports both Light ON and Dark ON modes, while the 5J03M is Light-ON only. The XB4 body is larger (50 mm width vs 19.3 mm) — check cutout clearance before dropping it in.
